There is a disconnect in analog IC design. A separation between system level and implementation level design activities has crept up on us. The analog world seems to have evolved into two realms: equations and spreadsheets on one side; netlists, polygons and Spice on the other. It is like a split between the right brain and the left, leaving us struggling to combine technology with art.
From the circuit simulator point of view, the system level has been the poor relation – just think of all the highly optimized variants of SPICE that are out there. In particular, since system analysis is done at a high level of abstraction and runtimes are relatively short, runtime efficiency for analog system simulators is often neglected. Opportunities for deeper and more comprehensive analyzes are missed.
Dealing with these two issues – the separation of specification from implementation and the lack of
optimization in analog system tools – results in significant benefits to the whole analog design flow, from specification through implementation to silicon test.
As we show in this article, a small investment at the system level can result in huge overall benefits to Analog/Mixed-Signal/Radio Frequency (RF) projects.
