How to increase the speed of ISim based hardware co-simulation?

描述

Because of long simulation times, the ISE tools offer a Hardware Co-Simulation tool to increase the speed of critical logic by implementing that logic in hardware and using that logic as a simulation co-processor. Because simulation speed is the primary motivation for using HW-Cosim, are there any additional steps that can be taken to increase the simulation speed?

解决方案

In the 14.1 ISE Simulation Tool (ISim), a new switch has been added to increase the simulation speed. This switch is as follows:

"-hwcosim_no_combinational_path "

This switch allows for faster simulation times by disabling internal processing logic for combinatorial feed-through paths.

This switch is available only in the ISE 14.1 and later tool versions. For a solution to an earlier version of ISE tools, please contact Xilinx Technical Support for assistance.
