How to speed up "10G/25G Ethernet Subsystem" simulation

Description

10G/25G Ethernet Subsystem logic simulation takes a long time to complete.

Is it possible to speed up the simulation?

Solution

The SIM_SPEED_UP option can be used to change the STARTUP_TIME and other timer settings, in order to speed up simulation.

Note: this change can be made only in simulation. For a design to work in hardware, do not define SIM_SPEED_UP.

VCS

Use the vlogan option +define+SIM_SPEED_UP

ModelSim

Use the vlog option +define+SIM_SPEED_UP

IES

Use the ncvlog option +define+SIM_SPEED_UP

Vivado Simulator:

Use the xvlog option -d SIM_SPEED_UP
