How to speed up simulation in Modelsim SE 10.4

Hi,

I use Modelsim SE 10.4 to simulate LDPC IP core generated by Quartus, but it runs too slowly. It uses 1 second to simulate 4 clock periods. How can I speed up the simulation?

Depending on your install, your simulator resolution may be picosecond by default. Check your modelsim.ini and look for the Resolution variable under the [vsim] header.

Alternatively, you can force the resolution on the command line. You are very close to your example. The syntax is vsim -t ns for nanosecond resolution.

Hi Sanket_Doshi:

The Resolution variable under the [vsim] header in my modelsim.ini had already been setted as  nanosecond. But my simulation on LDPC IP core runs very slowly. I want to know how to speed up the simulation. The modelsim's verison is ModelSim SE-64 10.4.

Thank you!
