questasim schematic painfully slow

[erik_ski]

Hi everyone, 

me and my colleagues are having trouble using questasim's schematic view. It becomes extremely slow (~0.2 fps or 5 seconds per frame) , a bit faster with extremely simple designs like an adder, but still not usable. We have tested questa 21, 24 on ubuntu 22 , 24 and centOS stream 10. It looks like something too big for not seeing any similar questions on the internet, which I didn't, so I'm guessing there is something wrong with the configuration. 

We're using the free license.

Thank you in advance!

I would suggest using the Quartus RTL Viewer instead to check the schematic view.

We primarily use Questa Altera FPGA Edition for simulation purposes, but not much for viewing schematics.

Also, which Questa FPGA Edition are you currently using?

Regards,

Richard Tan

Thank you. I'm using FPGA Starter Edition 2024.3. It has surprised me that the compatible OSes are only redhat 8 https://www.intel.la/content/www/xl/es/support/programmable/support-resources/design-software/os-support.html

Do you think a different license could make a difference? 

Best regards,
