Questa - time precision

[Melchiors]

Hi guys!

It is possible to set the precision of the simulation in Questa to femtoseconds? (I'm using version Starter Edition 2021.2)

I didn't find how to do it. Please, if it's possible, let me know how I can do it?

Thank you very much.

You may use timescale to do it, https://www.intel.com/content/www/us/en/docs/programmable/683080/23-1/vcs-and-vcs-mx-guidelines.html

Try with this design example
