Accelerate Modelsim Simulation

Hello @ Everyone,

is there a way to simulate faster with Modelsim (10.1a)?

I discovered, when I remove fast changing signals like the system clock it gets faster.

As I use PLLs in the design I need to set my simulator resolution to 1 ps.

vsim -t 1ps work.Testbench

    Easiest way would be to try an avoid big models, like the PLL. It tends to be slow. Provide the clocks yourself.

    If its a system level test, probably not a lot you can do.

    Yes, it is the system level test. But your hint with my own clocks is good!

    yeah - you can usually rely on the altera IP to work. So why do you need to simualte it? modelling it is usually easier, and especally if you dont need the locked signal outputs.
