9.2i CPLDFit - FATAL_ERROR:Cpld:Portability/export/Port_Main.h:127:1.127 when connecting BUFGTS to OBUFT

Description

Why do I receive a fatal error in Fit when I try to connect a BUFGTS to either an OBUFT or an OBUFE in 9.2isp3?

FATAL_ERROR:Cpld:Portability/export/Port_Main.h:127:1.127 - This application has

discovered an exceptional condition from which it cannot recover. Process

will terminate. For more information on this error, please consult the

Answers Database or open a WebCase with this project attached at

Solution

This is a bug in the tools that will be fixed in a future version of the tools. To work around the issue, add the -noopendrain switch to the Other CPLD Fitter Command Line Options in the Fit Properties.
