For years, there have been rather distinct domains for the extraction of interconnect models from physical design data.

Chip designers commonly focused on RC parasitics for circuit/path delay calculations and dynamic I*R voltage drop analysis.  The annotation of extracted parasitics to a netlist model required the layout… Read More

While there’s a lot of cool technology in modern semiconductors, it’s important to raise our sights periodically to understand how well these chips will work in the systems for which they are designed. One area driving a lot of semiconductor growth is automobile electronics. We’ve had drive-train control forever it seems, but… Read More
