Workstation spec for top-chip simulator

[Vanderpollator]

I am thinking for the workstation upgrade in the near future and we may purchase top-chip mixed-signal simulator, e.g., UltraSim. I am not sure our current server for 3 designers (eight 2GHz CPU cores, 32GB ram and 1.4TB SCSI disk) is good enough or not. Can anyone who has the experience of top-level simulation give me some advice? I understand you can control the accuracy level to affect the CPU time significantly but I just want to have rough idea that "Money aside, how powerful the workstation that I may need?" Thanks.

I simulate chips on a desktop PC with a couple of GB of RAM and only 2 cores, a few years ago I had a lot less power. It can still take a day or so to simulate a chip, but that's using spectre instead of Ultrasim (which should be faster for a whole chip). As far as I'm concerned (and there may be other viewpoints), it's simply a trade off between speed and cost(processing power)
