Practical Aspects of Modeling Complex Analog Behavior in Modern Circuit Simulators

September 7, 2017 @ 4:00 pm

- Free

Analog simulators allow complex behavior to be modeled and are a critical part of Computer-Aided-Design (CAD) tools used by designers to predict circuit performance. Early generations of simulators were inseparable from the specific transistor models integrated in their program. Resource-limited commercial simulator vendors would pair off with university and industry groups to add select models to their simulators while designers were restricted to simulators that support the models that they needed. Custom simulator interfaces were never successful as these interfaces were often quite complex – and each vendor’s interface was unique so the effort had to be repeated for each. Model developers realized that hardware description languages (HDLs) such as Verilog with a few changes could provide a simple and portable way to implement complex model equations. This talk will describe how this standardized subset Verilog-A has changed the way “compact” transistor models are developed. We will illustrate how easy it is for anyone to create a model not just for electrical simulation but for any analog behavior. It is now possible – and has been demonstrated – for individual developers to invent models with as much influence on the industry as models coming from large university research groups.Speaker: Dr. Marek Mierzwinski Keysight Technologies
