My former co-worker, Kenneth Bakalar at Mentor Graphics is an expert in AMS modeling languages and UPF
methodology, so he recently teamed up with Eric Jeandeau to author an interesting white paper: Interpreting UPF for a Mixed-Signal Design Under Test
. This white paper is based on a presentation made at DVCon
earlier this year. The basic idea presented in this 16 page paper is that modern SoCs use lots of power-management techniques to power-down and power-up blocks in the quest to conserve power, and that you should be able to model the effects of this in a UPF-based simulation flow.
