12.x/13.x ChipScope IBERT GTH - "ERROR:sim - runPar : IBERT:par: Timing for this design was not met..."


When I generate an IBERT GTH Core with DATAWIDTH=32 and more than one GT quad selected, the following error occurs:

"ERROR:sim - runPar : IBERT:par: Timing for this design was not met. Reduce the number of GTs enabled, reduce your line rate, and/or choose a faster device.

ERROR:sim - IBERT:par Check report example_chipscope_ibert.par for more information."

How do I work around this issue?


When generating the core, select DATAWIDTH=40. This allows the core to generate without any implementation issues.
