computer specifications for cadence applications

jimito13

Hi,

I want to create a new PC in order to run as fast as possible post-layout simulations for my circuits.At the moment i am using a system with 4 processors (Intel's Processor with 4 cores) and 6GB of RAM.The problem i face is that i need approx. 15 minutes for a dc & ac analysis (ac analysis from 100K to 1.5G with 1K steps logarithmic) and this is quite annoying especially when time for tape out is limited.I want to hear from an expert here a suggestion for the synthesis of a powerful PC configuration for the purposes i mentioned above,that is what is the best recommended solution for the processor and memory requirements?I should note that the computer is intended just for personal usage and will NOT be a workstation for more users or part of a company's network,i mention that in order to give you an idea for the amount of budget i can afford but in any case let's don't take this parameter into account!

If there are some more tricks that i can get the best out of my pc's power i want to here them (except turbo Mode in spectre,parasitic reduction that i am already aware of).

Thanks a lot in advance.

Best Regards,

Jimito13

  • I'd have to follow up with my colleague but for now let's assume his design is roughly the size of jimito13's, although I don't think its actually that big. I don't recall what the subversions are but I know he's using IC614, MMSIM72, ASSURA41, EXT91. We lag a bit behind because of our foundry PDK's supported versions, however I did encourage keeping both the foundry supported version and the latest version to make things easier when working with both the foundry and Cadence support engineers. I don't know if anything has been done to tweak the simulator settings, all I've been told is that it's 'slow'. I am waiting to get details on the circuit being simulated, the types and duration of simulations, etc., but I think the solution for jimito13 would be good in my colleague's case as well (even if it's beyond what he needs, optimizing cost is not a big deal for a single machine in his case).

    BTW you can learn more about APS here: http://www.cadence.com/Community/blogs/cic/archive/2009/02/18/video-demo-spice-2-0-the-abcs-of-aps.aspx
