2.2.4. Increasing Simulation Speed in ModelSim and Questa Simulators

By default, the ModelSim and Questa simulators run in a debug-optimized mode.

To run the ModelSim and Questa simulators in speed-optimized mode, add the following two vlog command-line switches. In this mode, module boundaries are flattened and loops are optimized, which eliminates levels of debugging hierarchy and may result in faster simulation.

This switch is not supported in the Questa* Intel® FPGA Edition simulator.
