How can I speed up the simulation time of the PCI Express Hard IP?

Description

You can set test_in[0] on the PCI Express® DUT model to “1” to accelerate the MegaCore® function initialization counters. Also, you must set the rp_test_in[0] on the BFM Root Complex to “1” if using the testbench and BFM Root Complex.

 

The simulation can also be speeded up by modifying the following testbench VHDL generics/Verilog HDL parameters:

 

a) set "FAST_COUNTERS" to "1" to make the timing counters in the PCIe® core operate faster.

b) set “PIPE_MODE_SIM” to "1" to enable PIPE as opposed to serial mode simulation in the testbench.
