Reply To: Waveforms not generated correctly (GHDL)

I don’t advertise simulations with Vivado xSim
* very low speed (>10x) compare to commercial simulators or open-source simulators
* creates masses of output data (multiple GB where others write just a few MB)
* explicit VHDL features like range checks need to be activated by the user (if not, xSim doesn’t produce correct simulation results according to IEEE Std. 1076)
* limited VHDL-2008 support

Do you really need to mistrust your synthesis tool? What are you using?
If there is no real concern and proof of mistrust, don’t spend hundreds of ours in post synthesis simulations. It’s awful slow.

I didn’t get the point why you need breakpoints for post synthesis simulation. Breakpoints are for debugging and step-by-step investigations of designs.
