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!
