Analog Modeling - Part 3

Posted Feb 10, 2012, by Mike Jensen

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

Analog Modeling - Part 2

Posted Feb 2, 2012, by Mike Jensen

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

Analog Modeling - Part 1

Posted Jan 25, 2012, by Mike Jensen

I recently spent some time rummaging around my basement. I suppose my basement is not unlike many others — it’s kind of my family’s catch-all storage place for items too big to fit in a closet. Besides housing my HVAC and water heating systems, my basement is home to a variety of holiday decorations, lots of canned, bottled, and bulk food items, a small collection of mismatched folding tables … Read More

Connecting Tools and Processes

Posted Jan 13, 2012, by Mike Jensen

Searching the Internet is like having a giant, international reference library at your fingertips. If you know what you’re looking for and have a reasonable idea of where to look, with a little patience you can usual find some pretty interesting material related to your search topic – okay, you can also find a bunch of stuff you aren’t looking for, but as I often say, “That’s a topic for a different … Read More

Use vs. Experience

Posted Dec 10, 2011, by Mike Jensen

Whether your company creates airplanes, cars, widgets, or software, product planning is an essential part of the development process. And if your group is like mine, product planning meetings are seldom boring. I am privileged to work with some pretty sharp folks who are very capable engineers, and very passionate about what they do. Our planning discussions are always interesting, and often animated. … Read More

Analyzing the Big Picture

Posted Dec 2, 2011, by Mike Jensen

As engineers we often use “system” to describe different levels of design abstraction. Chip designers refer to integrated circuits as systems on chips. Audio designers refer to an amplifier as a system. Aircraft brake designers create systems for stopping aircraft. There truly are a variety of ways to define and implement a system. And most things we call a system are really just a subsystem … Read More

Simulating for Reliability

Posted Nov 21, 2011, by Mike Jensen

An important performance metric for any system is reliability — does the system do what it’s supposed to do, when it’s supposed to do it, time after time, without fault or failure. Obviously, system reliability doesn’t just happen; it’s not just dumb luck when a system delivers flawless performance, whether it’s your car, your cell phone, your garage door opener, or your … Read More

SystemVision 5.8

Posted Oct 21, 2011, by Mike Jensen

It’s software release time in the SystemVision® offices, and we are pleased to announce that SystemVision 5.8 is ready for immediate download. I say “pleased” for two reasons. First, users will no doubt find good value in the many new features and updates. And second, SystemVision Engineering can take a break from their keyboards, and maybe even take a well-deserved nap (getting a … Read More

VHDL-AMS Model Portability -- Fact or Fiction?

Posted Oct 12, 2011, by Mike Jensen

Once in awhile I work with customers who want to move VHDL-AMS models between multiple simulators. The ability to do so is one of the great promises of standard modeling languages and, at face value, should be an easy task. After all, if a language is an industry standard, and multiple simulation tools claim to support it, then moving models between tools should be a plug-and-play process, right? Well, … Read More
