Improving Virtuoso Speed

patschouly

Hi,

I'm unsure if this is a concern for the Support, but the setup we use with virtuoso (ICADVM18) is pretty slow. I need to wait a few seconds for every window to open, a time during which I can see small dialog windows popping up for a few milliseconds. Even more, this affects nearly every task: Scrolling in layout, starting simulations, opening simulation results etc. takes for ever.

I'm not sure what exactly is going on, I guess the PDK we're using is adding some stuff which needs some computation time, but the difference is tremendous (compared to a simpler PDK we use for our students).

Besides support, is there anything I can look for myself? Can I turn off some submodules I don't need? I'm not sure if this is a valid complain, but even a simple DC simulation without any loading of model files, only analogLib components takes 10 to 20 seconds, of which the actual simulation time is below one second.

Sorry, I'm aware that this is very broad and difficult to debug from remote, but perhaps there are some tips on how to improve general performance.

Kind regards,

Patrick

    same trouble here, is there a way to use some open source IDE to load the spectre simulator?

    I've absolutely no idea what this means, or what it has to do with the original question either. The original question would have been best served by contacting customer support so that an application engineer could help diagnose the performance problem.
