If you are interested in electronics, history, or simple amazing stories, you will enjoy this podcast interview with our Moore’s Lobby host, Daniel Bogdanoff. Mike Engelhardt has been developing simulation tools since 1975. He is best known for creating LTspice, which is believed to be the most widely distributed and used SPICE analog electronic circuit simulator in the world.
Recently, he realized that he could take advantage of the massive improvements in both hardware and software to develop a radically improved circuit simulation engine; thus, QSPICE was born. Engelhardt explains how he created a better SPICE tool that could dramatically increase simulation speed while simultaneously improving functionality, accuracy, and reliability.
As you will hear, Mike’s amazing career includes developing simulation tools for applications as diverse as scanning electron microscopes and locating underground petroleum deposits. Here are a few more teasers about what you will hear in this far-ranging discussion with Engelhardt:
-The biggest early roadblock to simulation adoption in the EE world.
-Why simulations are more important than hardware to an engineer.
-The importance of time-domain simulation.
-Insights into QSPICE for power simulation of wide bandgap semiconductors like GaN and SiC.

Ananth Avva is “a big believer that if you give human beings the right type of information and you contextualize it, they will make the right decision ultimately for the organization.” In his current role at Altium as the Senior Vice President and General Manager of Cloud Platform, he is leading efforts to improve and accelerate collaboration because “collaboration trumps everything else” as it drives speed to market, lower costs, and more efficient development.
He has seen companies attempt to transition engineering teams to software-as-a-service (SaaS). In his experience, “that usually goes sideways pretty fast.” With Altium 365, Avva and his team are trying to seamlessly bring SaaS into engineering.
Their goals are to enable what they call shifting left and shifting right. When shifting left, they aim to take decisions that were traditionally late in the product life cycle and move those requirements earlier in the design process. This can allow the procurement, operations, compliance, and manufacturing teams to provide vital context for better design decisions. Similarly, shifting right passes design information downstream more quickly to avoid costly delays or respins.
If your organization is developing electronic products, you will benefit from this Moore’s Lobby podcast discussion hosted by Daniel Bogdanoff. Avva explains that companies consistently overestimate the cost of change and underestimate the benefits. They may also have the wrong “whys” behind why not to change. He goes on to explain that these can be “a bit of a phantom menace.” In his opinion, these are changes all companies will need to make to remain competitive in the market:
Let's say you don't do it. The world is headed that way anyway, so what happens? Let's fast-forward five years, you're gonna have to do it.

Thomas Keller is the Director of Platforms and Core Technology at u-blox. He learned early in his career that technology development does not always progress in a perfectly straight line. During his PhD studies, he worked on Orthogonal Frequency-Division Multiplexing (OFDM) as a candidate technology for 3G cellular network deployment. OFDM lost that initial tech battle to Code-Division Multiple Access (CDMA) but later returned in LTE cellular systems.
In this fascinating conversation, Keller discusses the challenges facing the industry today as low-power, low-bandwidth, low-cost IoT devices attempt to connect to a 5G network focused on high-power, high-bandwidth, low-latency applications. Interestingly, much of our current 5G networks are still relying upon an LTE backend. What happens when LTE goes away?
In this Moore’s Lobby podcast with our host, Daniel Bogdanoff, Keller offers his thoughts on what should come next and guidance for developers who need to navigate the phase-out of LTE worldwide. This interesting topic deserves thoughtful consideration and impacts system designers and companies across a wide range of industries.

If you enjoy hearing passionate people talk about jobs they love and technology that fascinates them, you are in for a treat. Noah Gedrimas grew up with a love of vehicles—cars, tractors, construction equipment, and snowmobiles.
In college, he built a one-fifth-scale car and then programmed it to self-park, which led him to a “newfound respect for mechatronics” and its ability to support really complex maneuvers. In this interview, Gedrimas reflects with enthusiasm on his time at Continental Automotive, working on everything from autonomous valet parking to electric shuttles and semi-trucks.
Now, Gedrimas is applying that passion to ground-positioning radar technology at GPR. They are using ground-penetrating radar to capture unique, sub-surface data for positioning. Inclement weather compromised line of sight, roads with poor or no lane marking, weak GPS signals, and road terrain no longer affect the uptime and availability of autonomous navigation.
You will want to join our host, Daniel Bogdanoff, as he chats with Gedrimas about:
-Cadavers in cars.
-The feature-rich information that lies below the ground.
-The compute requirements when compared to cameras or lidar.
-Early adopters of GPR technology.
And much more that you will not want to miss.

After beginning his career with Hewlett-Packard, David Su met a friend for lunch to learn about a new startup called Atheros. He was so excited by the vision to develop world-changing products that Su “went for lunch and never left.” At Atheros, Su had a “front-row seat” developing wireless WAN technology that transitioned from novelty to necessity while Atheros grew from a startup to a billion-dollar behemoth. That little startup was eventually acquired by another company you may have heard of: Qualcomm.
And what led Su to get involved with another startup? Well, lunch, of course. Su and his friends recognized that they could use their design experience to help fix a problem that was partially of their own making: battery consumption for wireless RF products. This was the genesis of Atmosic.
With his decades of design experience, Su admits that he stands on the shoulders of giants when creating new low-power products. The company has recently expanded its RF IC offerings from Bluetooth to Zigbee and Matter over Thread.
When asked how an IC design team knows when they have become either too structured or too unstructured, Su thoughtfully answered that if you never create anything innovative or your chips don’t work, you have probably fallen into one of those two ditches.
You will want to join our host, Daniel Bogdanoff, as he discusses CMOS RF, energy harvesting, and the importance of teams with Su. They touch on many other interesting topics including:
-What he remembers most fondly from his days at Atheros.
-A development failure for one technology that led to success for another.
-The balance of circuits, system, and software design necessary to optimize product performance.

Steve Klinger, Vice President of Product, joins the Moore’s Lobby podcast to discuss how LightMatter is using silicon photonics to improve speed and reduce power consumption in AI data centers. With two previous $1B+ startups under his belt, Klinger knows a thing or two about identifying successful technology solutions to current industry challenges. While compute performance continues to grow rapidly, interconnect has not been able to keep pace. In this episode, Klinger explains how LightMatter’s flagship product, Passage, creates a programmable optical fabric for the efficient interconnect of chiplets and other silicon ICs.
Klinger explains that they are trying to solve the problem of efficiently accessing all of the bandwidth on one chip and sharing it with another chip. If they can improve the interconnect bandwidth density, it will allow performance scaling to continue increasing at the workload level. Klinger emphasizes, “There are data centers with hundreds of millions of dollars of GPUs sitting idle, waiting for the network topology or the interconnects to catch up.”
So, join our host, Daniel Bogdanoff, in this deep dive into silicon photonics with Klinger. In this discussion, they address many fascinating topics, including:
- What makes silicon photonics unique from traditional photonics?
- The common traits shared by Klinger’s previous $1B+ startups.
- The many job openings available at LightMatter.

While leading the system design of new head-word displays for fighter pilots, Tomide Adesanmi was most excited when he got a chance to innovate. However, like most electronics design engineers, he found that the majority of his time was spent searching distributor sites for components, drawing symbols, and working with spreadsheets.
Engineers can also relate to the anxiety he felt, worrying that he might have made a silly mistake by missing a tiny detail on “page 243 of the datasheet” for a microcontroller. So, he quit his job to try to tackle the mundane problems of design using “good software, good algorithms, and electronics.” A few months later, Circuit Mind was founded.
Adesanmi and the Circuit Mind team aim to allow designers to quickly optimize designs with variable weighting on size, power, cost, parts availability, and more. Our Moore’s Lobby audience of electronics engineers will definitely want to listen in as our host, Daniel Bogdanoff, and Adesanmi chat about the possible future of circuit design. You will hear:
-Why it is important that Circuit Mind uses deterministic algorithms as opposed to machine learning.
-Defining the team and roles necessary to build these new tools.
-What company makes the best datasheets?
Contact Circuit Mind to schedule an appointment to learn more, get a demo, receive a quote, or even run a trial of your design on the ACE platform.

Over the course of his fascinating career, Mark Himelstein has worked on several significant computing technologies at historic companies like MIPS and Sun Microsystems. He has also worked as a consultant in various roles that include architect, VP of engineering, and advisor. However, RISC-V may have a greater impact on the computing field and our world than any of those previous efforts.
Himelstein gives us an insiders view on the open standard process that is often “cooperation and competition, simultaneously.”
“The thing that keeps us as a community is the effort in the software ecosystem. Nobody wants to really go off and go on their own. They just don't want to do it. It's just too costly. I don't care if you're the biggest company in the world or the tiniest.”
Listen in on this episode of the Moore’s Lobby podcast as Daniel Bogdanoff and Himelstein chat about a wide range of interesting topics that include:
-How Himelstein encourages people to get involved with RISC-V by telling them to not just complain about something, but join in to help make it better.
-The significance of vector operations for computing and how those advantages may soon be extended to matrix operations within the ISA.
-Three major things RISC-V is currently working on for future release.

Daniel Cooley started his career in RF chip design at Silicon Labs and now leads technology and product development at “the number one wireless supplier” for the Internet of Things. In this thoughtful interview, Cooley explains why adding wireless connectivity is only the first step to completely rethinking product designs and features. He noted that “the home run cases aren't where wireless is the feature; it's where wireless made that product better.”
Cooley explains that Silicon Labs’ primary goal is to help companies get started with their preferred wireless protocol quickly and efficiently so they can focus on their applications instead of trying to debug the wireless links. Silicon Labs’ experience was forged on having “cut our teeth selling more than a billion wireless chips over many, many years.”
Our Moore’s Lobby host, Daniel Bogdanoff, chats with Cooley about a range of fascinating topics that include:
-Building wireless products for “metal benders.”
-The surprising economic benefits of adding wireless connectivity to shelf labels.
-An explanation of the Matter protocol and why it is important.
-The Silicon Labs partnership with Arduino.
-Why the sky is falling…or at least the cloud is coming down.
-Reflection on a major project and when Cooley “realized none of it was going to work.”
-Why Cooley believes we will see a rethinking of the Internet infrastructure around non-human electronic devices.

While Moore’s Law scaling has driven incredible advancements in computing, AI, and smartphones, many applications don’t need or benefit from the most advanced semiconductor nodes. From its inception, Pragmatic Semiconductor’s goal has been to take a…well, pragmatic…approach to develop an ultra low-cost, fast cycle time alternative to traditional silicon processing. Oh, and did we mention that the resulting chips and wafers are also flexible?
You will definitely want to check out this Moore’s Lobby conversation between White and our host, Daniel Bogdanoff, as they dive into:
-The technology and manufacturing of thin-film silicon
-Europe’s largest-ever VC funding for a semiconductor company
-The potential advantages of flexible silicon for building a more robust supply chain
-White’s top priorities for improving the flexible silicon ecosystem

A decade after demonstrating the first entanglement of semiconducting spin quantum bits, or qubits, Oliver Dial and IBM Quantum are developing the ICs, cryogenic systems, error mitigation techniques, and software tools that will identify solutions to problems beyond the scope of classical computers. Recently, the IBM Quantum team announced the Heron 133-qubit and Condor 1,121-qubit quantum processors, and Dial joins us to talk about a subject that he loves.
The highlights of this conversation between Dial and our Moore’s Lobby host, Daniel Bogdanoff, include:
A comparison of quantum and classic Turing computing systems. Temperatures down to 0.1 kelvin (brrr!) to noise temperatures of 30,000 kelvin (hotter than the sun, but not really). An audio symphony of quantum circuits running computations from around the world. Qubits are probably much bigger than you would expect. Why packaging engineers are the unsung heroes of the semiconductor and quantum industries. Semiconductor engineers telling quantum engineers, “you guys are doing these all wrong.” The technology advance in the newer Heron processor that Dial is most excited about. -
Optimizing energy generation and consumption requires accurately measuring currents and voltages. In addition, to maximize overall efficiency, that data must be shared in real-time or near real-time.
The highlights of this conversation between Henrik Mannesson of Texas Instruments and host Daniel Bogdanoff include discussing:
-The differences between power management in the home or small factory and power management at the grid.
-The evolution from smart metering to energy management.
-The importance of accuracy in power measurement and how to achieve it.
-The benefits of staying with a single company for many years.

Silicon transistors naturally get most of the attention. However, delicate silicon microelectromechanical systems (MEMS) with movements that are often measured in angstroms are making some noise of their own (metaphorically, because you won’t be able to hear those tiny vibrations!).
By focusing in parallel on the MEMS device and the silicon processing required to build them, SiTime has been able to improve MEMS resonator performance “close to 100,000” times, says Fari Assaderaghi, EVP of Technology and Engineering at SiTime.
Assaderaghi went on to state:
“Timing is like an unsung hero that is behind the scenes, but its performance actually limits or enables certain performance characteristics that you see at the end systems.”
Over his career, Fari learned many important lessons that he shares during this thoughtful interview. One of these is to “always go back to first principles.” He expounds on this by stating, “If you don't understand something, don't paper over it. Keep on digging.” He concludes with the warning, “There is no shortcut, and if the fundamental doesn't support it, eventually it's going to come and get you.”
Assaderaghi also learned to focus on your ultimate goal rather than what you think is possible. “If you start with what you want to achieve...you would be surprised that eventually what you thought was not possible, actually it is possible.”
Our Moore’s Lobby host, Daniel Bogndanoff, also discusses with Assaderaghi his fascinating personal journey. Over his career, Assaderaghi has had the pleasure of working alongside luminaries like Chenming Hu, the father of Finfets; Robert Dennard, the inventor of single-transistor DRAM; and Lisa Su, CEO of AMD.
Other highlights from this interview include:
-The unique SiTime culture that Fari credits to the CEO, Rajesh Vashist.
-The importance of failure
-The tuning of silicon’s mechanical properties, not just electricalThat’s a wrap on Season 6 of Moore’s Lobby. We hope you have enjoyed hearing from these amazing guests as much as we have. Please tell us what you think in the comments or share your suggestions and requests for guests and topics for Season 7.

It all began with a love of mathematics. Adil Kidwai loved mathematics. That initially led him to a career focused on analog and RF design. After many years working on RF technology leading efforts in cellular communication, Wi-Fi, and Bluetooth, Adil had a chance to move into the AI field.
When he started digging into AI, Kidwai had an epiphany. “I realized that AI borrowed a lot of concepts from information theory which were developed 50 years ago.” The mathematics of RF communication and artificial intelligence were basically identical: convolutions, matrix multiplication, nonlinear operations, and more.
It was during this time that Kidwai met EdgeQ CEO and founder Vinay Ravuri for lunch, and it “just clicked”. Kidwai recalls that they were thinking exactly the same things about the relationships between AI and 5G. So, Kidwai joined EdgeQ, where they have developed an integrated circuit that leverages the customization capabilities of RISC-V to enable and optimize both AI and 5G.
They believe that their “software-defined base station-on-a-chip” allows AI to complement 5G in some applications and 5G to complement AI in others. As Kidwai notes, “these two technologies support each other in the world that we are living in.” And, they already have their eye on 6G.
In this Moore’s Lobby interview with our host Daniel Bogdanoff, Kidwai shares how different it was when moving from a behemoth like Intel to a startup. “You have to move like 100 mph on day one!…because it’s a question of existence all of a sudden.”
Here are a few other highlights from this interview with Kidwai:
-Think your master’s thesis was difficult? Wait until you hear what Kidwai had to accomplish at UCLA.
-His reflections on spending several years in Munich working on Intel’s acquisition of Infineon’s wireless group. He even has some recommendations for people considering moving abroad.
-The surprising changes in the wireless world Kidwai has seen in his decades working in the industry.
There is much more, so go listen for yourself! Please tell us what you think in the comments. We would also love to hear your recommendations for the companies and people you would like to hear from in future episodes of Moore’s Lobby.

Imagine 1500 laptops strapped to a 120 foot (36 m) wide sprayer being pulled behind a tractor. That gives you a rough understanding of the compute power inside the John Deere See & SprayTM that targets herbicide to the weeds, not the crops. These might be “the smartest agricultural machines in the world,” says Chris Padwick, Director of Computer Vision and Machine Learning at Blue River Technology, a wholly owned subsidiary of John Deere.
Padwick was not looking to return to his agricultural roots, but in a “shields down” moment” he was approached by a startup, Blue River Technology. He recalls being “completely blown away” by what they were doing in computer vision.
After initially developing a product for lettuce thinning, Blue River pivoted to the problem of row crop weeding. In the US alone, the agricultural industry uses over 20 million gallons of herbicide annually, almost all of it through broadcast spreading across the entire field. Blue River set to work on changing the paradigm to only spray the weeds. According to Padwick, this “dot matrix printer for weeds” has the potential to “save 15 million gallons of herbicide” and “about a billion dollars.”
In this episode of the Moore’s Lobby podcast, Padwick takes us behind the scenes to discuss the challenges of data collection in the fields, image classification, the compute technology that drives these real-time systems, and much more. On this business side, he reflects on the 2017 acquisition by John Deere and how important that was in their development of products at scale that can operate in rugged environments for two decades.
“I feel like we're going to look back on farming in five or ten years and we're just going to be amazed…Precision spot spraying is going to be the way that people treat their crops going forward because it's going to allow them to save so much more chemical. And the sustainability in the environment is kind of unparalleled. So I really feel we're kind of at that inflection point for agriculture.”
So, listen in on this fun interview as Padwick describes:
- His graduate research into Big Bang cosmology and background radiation
- Why he left engineering as an undergrad—seriously, universities we have to fix this outdated solution to engineering education!
- Blue River’s global operations to collect crop and weed images to drive continuous improvement

In this unique episode of the Moore’s Lobby podcast, we get to hear from not only the technologists and executives behind the company but the investor who is helping them make their dreams a reality.
As an electrical engineer, Chrissy Meyer had spent years working in product design on large projects at Apple, including the Apple iPod Nano and Touch. She is all too familiar with the outdated methods of hardware collaboration and design reviews—printed schematics, highlighters, and engineers huddled around a conference room table.
According to Kyle Dumont, a first-time entrepreneur as Allspice CTO, their goal is centered “around making it easy to build a workflow and collaboration process for electronics designs.” In his earlier career working in hardware at both large and small companies, he also “became pretty frustrated with how difficult it was to collaborate on our electronics designs.”
Valentina Ratner, CEO of Allspice, goes on to explain that the industry is “trying to build colonies in Mars, and I don't think we're going to get there with Google Sheets and PDFs and screenshots.”
In her current role as a partner at Root Ventures investing in early-seed tech startups, the engineer inside Meyer had a “visceral” reaction when Ratner and Dumont explained their vision to bring Git-style collaboration software to the hardware world. Meyer explains that “there was never a doubt in my mind that this problem that they were describing was very real. Because the truth is I had lived it for 15 years.”
Meyer said, “I had to take off my engineering hat for a quick second and say, okay, reign in the excitement. Yes, this is a fantastic product for an engineer. Is this a great investment?...the truth is, there are far fewer electrical engineers than there are software developers.”
With the backing of Root Ventures, Ratner and Dumont founded Allspice and quickly got to work. As a first-time entrepreneur and CEO, Ratner admits that she had to learn a lot quickly because “there are just so many unknowns.”
Reflecting on some early lessons, Ratner shares some interesting advice for fellow tech entrepreneurs:
“It's less about convincing anyone and more about finding the people that already believe in the version of the world that you're trying to build.”
Other highlights of this round-table discussion include:
-Meyers’ belief that “'there's this common misconception that in order to approach VCs, you need to have a fully polished pitch deck, and you need a financial model and forecasts and projections.”
-Insights on one of the favorite features of Allspice: the ability to run digital, asynchronous hardware design reviews
-Where Meyer thinks hardware and software companies are going to win in the future

Engineering careers, even very successful ones, don’t always progress in a nice orderly manner. In this episode of Moore’s Lobby, Peter Wawer, Division President of Green Industrial Power at Infineon Technologies, retraces a fascinating technical and business career that is still going strong.
As a second-generation electrical engineer, the industry still excites him. Wawer says that electrical engineering is “a fascinating topic” that allows you to “innovate and develop things to the greater good.” In his encouragement to the next generation of engineers, he states that “it's very rewarding tackling the issues and the challenges that we face” in society today.
Over the last decade, he has worked in power electronics at Infineon as they have invested and developed wide bandgap technology to serve important industries that are shaping our world: renewable energy, electrification, data centers, and more.
In addition to his extensive work on multiple leading-edge technologies, Wawer has been inside just about every corporate transition you can imagine. These have ranged from spinoffs and billion-dollar acquisitions to bankruptcy and government-rejected purchases.
When discussing major spinoffs like the creation of Infineon from Siemens, Wawer describes the “mixed” feelings within the company. Some view the larger company “as an advantage” by providing “more critical mass and more diversity.” While others see the benefits of a smaller company “being more focused.”
Wawer got started in the nascent silicon PV industry during his graduate studies and early career at Siemens. Then, after a number of years working on embedded Flash, he moved back into the solar industry; a time that he describes as “big fun” with the industry really beginning to take off.
In this Moore’s Lobby conversation with host Daniel Bogdanoff, Peter Wawer also discusses:
-The history and differences between thin-film and thick-film solar
-Why different semiconductor memory technologies—DRAM and Flash—are not fabricated in the same fabs
-Unique characteristics of trench and planar silicon carbide MOSFETs
-The performance and reliability challenges that impact power electronics beyond just the semiconductors
