Elaboration of entities that are generated take very long time

Hi all, I have a design where I generate a large number (496) of enities. They are note very big in logic, around 13 ALM's in a CycloneV SOC. My problem is, that the elaboration step for these enti...

    So I had the opportunity to move our build machine to a Intel Proessor machine which makes my synthesis step roughly 50% faster, the fitter step not 50% but still remarkably faster. If you guys stumble over this post with the same issue, please drop a line in this thread in order to show Intel this is an issue.
    I will however stop investigation here since I am happy with this workaround.
    @KhaiChein_Y_Intel I am not allowed to share this design since it is under NDA Agreement sorry.

Hi,


May I know if you have any updates?


Thanks.

    Hi KhaiY

    Yes and No... I haven't yet finished the tests with smaller arrays, so no I have no updates for the Moment regarding this. But I have interesting information from another end: I moved to another physical machine that is meant to be slower regarding the technical spec's. Surprisingly it is more than two times faster for this entity elaboration and about 1.5 times faster in the fitter step. I know I am not allowed to share detailed benchmark data (for whatever reason), but the VERY interessting fact is, that the Processor which takes so much longer in elaboration step is a Product from an Intel competitor. There are other messages in this forum and on other sites in the internet reporting the same observations. It would indeed be interesting to have an official statement from Intel regarding these difference.

    Also i discovered, that turning off hyperthreading makes Quartus faster... Another fact where it might be interesting to have official information from Intel.

    Best regards
