How do I speed up my Verilog HDL simulation time in the ModelSim® software?

Description

By default, the ModelSim software runs in a debug-optimized mode. To run the ModelSim software in speed-optimized mode, add the following two vlog command line switches:

vlog -fast -05

In this mode, module boundaries are flattened and loops are optimized. This eliminates levels of debugging hierarchy, which may result in faster simulation.

This switch is not supported in the ModelSim-Altera^® simulator.
