Welcome to the third installment in my Analog Modeling blog series. In Part 1 I wrote about why equations are important for simulation. In Part 2 I suggested a process flow for turning device equations into a simulation model, and introduced the basic structure of a VHDL-AMS model. Now it’s time to begin the model definition process. As I outlined in Part 2, the first step is deciding what you want … Read More

As with all good inventions, you quickly wonder how on earth you could have done without them before. Relieving thermal bottlenecks reduce temperatures; it’s so blindingly obvious. Now that we have the ability to visualise with FloTHERM exactly where the thermal bottlenecks are in a design, the job of the (overworked/underpaid) thermal design engineer just got that more productive.
Electronic … Read More

Which vehicle offers the greatest number of safety features? By that I mean systems like adaptive cruise control, blind spot detection, or lane keeping. Safe to say it’s one that’s well beyond the reach of the average car buyer. But features like these are moving down-market rather quickly, so what moderately priced vehicle has the greatest number of safety features?
One candidate – and we’ll have … Read More

Do it right the first time – we all first heard this from our parents as kids, and throughout our lives. It’s no different now in our work as electronic design professionals. Do more up front planning, simulation and analysis, follow good design practices, etc. Are you really doing it though?
As electronic design professionals, we’re done when we get our product manufactured. At the end of … Read More

New technology is cool but… with most new processes there are risks to be managed.
Usually new technologies promises/offers higher design performance, lower product costs and or faster design turn around but, failing to manage the risks can cause all the benefits to go down the drain. Embedded Passives are no exception –on the contrary, there are many pitfalls that can result in bad boards –expensive … Read More

Some weeks ago, I published a posting from my colleague Richard Vlamynck, who was explaining the ideas behind System-C and modeling at different levels of abstraction. He promised to write more and I was very pleased to receive a new contribution …
It’s just me again, blogging about hardware models in general and System-C in particular.
Earlier, I’d mentioned the fact that System-C can be used … Read More

In Analog Modeling – Part 1 I reviewed the importance of equation selection in the analog modeling process. In a nutshell, the first step in getting good simulation results is choosing equations that best describe the behavior or device you want to analyze. Your analog equation set could be as simple as a single transfer function describing the relationship between the inputs and outputs of a … Read More

This geek is an all-around mil/aero enthusiast. Aircraft, spacecraft, ships, ground combat vehicles, unmanned vehicles, missiles—you name a mil/aero platform, and this geek’s interest is piqued. It’s not often that helicopters turn heads; however, Bell Helicopter has been successful in doing so over the past few months.
This geek previously discussed the Middle Eastern debut of the Bell Boeing V-22 … Read More

Infineon Technologies notes that higher performance power electronics components contribute to the primary automotive industry goals of better fuel efficiency and lower emissions. The firm suggests that power MOSFETs with current capability above 200A and R DS(on) below 1mΩ are needed to reduce conduction losses and improve overall efficiency, but it says that MOSFETs to fulfill these needs have not … Read More

As I spend a lot of my time talking about embedded software via a variety of media – conferences, articles, Web seminars, this blog are examples – I frequently get emails requesting copies of materials or posing questions. All of this communication is very welcome and I do my best to respond promptly and, where I can, usefully.
If I think a question might be of wider interest, it seems … Read More
