Light version of virtuoso

nrk1
nrk1 over 2 years ago

Long back, there were different executables icms(schematic/simulation only) and icfb(all tools). The former was lighter, I think. Is there a similar variant of virtuoso, or a command line argument that presents lesser load on the machine? Machines that are used by students in our courses tend to see a lot of virtuoso sessions from multiple students, but the circuits simulated are rather small, layout is not required most of the time. A lighter variant would help.

Thanks

    Nagendra,

    There is no light version, and no plans to do so. Typically the executable size is not the limiting factor (we see) but the memory consumption within the processes caused by (say) lots of simulation. We are doing some work to offload that into separate processes that maybe don't live as long, but in terms of reducing the executable size itself we've seen little benefit of doing that with modern machines (the increased testing needed, the risk of omission because of dependencies, and also the irritation of suddenly finding that you can't do something as a user without having to quit and restart a different executable rather outweigh that). We found, when we made this change over 15 years ago, that the vast majority of users just ran "icfb" anyway...

    Regards,

    Andrew
