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

  • How big is the circuit inventory? Have you tried the APS mode? Are you using the absolute latest MMSIM version - each MMSIM version (and even hotfixes of each) have had quite a lot of advances in simulation speed optimisation - so I'd first of all start by ensuring you're using the latest MMSIM10.1 hotfix version, and using APS. 

    If the circuit is sufficiently large - 8 or 16 CPUs will help even more.

    This is a bit of a difficult question to answer though - because it's definitely circuit dependent (especially the size of the circuit)

    Regards,
