Verifying all of an SOC-analog circuitry included

In this paper SOC-analog circuitry design evolution was discussed. Just as digital design did 15 years ago, analog design has now reached a transition and being implemented to CMOS devices. This has made analog circuits more functionally complex, and that complexity has led naturally to the need for analog functional verification. Like digital verification, the changes was led by experts in design companies, and the consulting companies were formed to help those without expertise.
