13.2 ISE Simulator: Hardware Cosim Fails to Implement Design if "-sd" Switch is Required in NGDbuild for NGC Inclusion


When running the ISE Simulator Hardware Co-Simulation, the following Xflow errors were observed in NGDBuild:

"ERROR:HWCoSim - Program 'xflow' reported the following errors:


ERROR:Xflow - Program ngdbuild returned error code 19. Aborting flow



ERROR:HWCoSim - Program 'xflow' returned a non-zero exit code 1. Please refer to log file '.....\xflow.log'

HDL wrapper and bitstream generation process failed."

It appears that the required NGC files were not being read into NGDbuild.


This is a known issue and a CR has been filed for a fix in a future release of the software.

For now, the workaround is to ensure that the NGC files required during NGDbuild are included in the run directory, so the need for the "-sd" switch in NGDbuild is removed. Alternatively, the NGC files can be explicitly added to the ISE project.
