Description
Due to a problem in the Quartus® II software version 12.0 SP1 and later, generated XAUI HDL files may be missing timescale options. This can result in the Cadence NC-Sim simulator generating the following error during elaboration.
ncelab: *F,CUMSTS: Timescale directive missing on one or more modules
Resolution
To work around this problem, modify the ncsim_setup.sh script to add the timescale
option to ncelab. For exampe:
ncelab -timescale 1ps/1ps <other options>.
This issue is fixed beginning with the Quartus II software version 12.1.
