The Luminary Stellaris MCUs also contain custom analog blocks such as oscillators, PLLs, and ADCs to support clocking and mixed-signal applications.

Designing and verifying these custom analog blocks impacts our time-to-market, and we constantly look for ways to speedup these tasks.

This article describes our use of the Analog FastSPICE circuit simulator (AFS) from Berkeley Design Automation for verifying the design of a crystal oscillator, transistor-level closed-loop PLL simulation, and characterizing a 10-bit, 8-channel ADC.
