SPI-4.2 v9.1 - NCSim timing simulation does not work with SDF file

Description

NCSim timing simulation does not work correctly with an SDF file. There are data mismatches caused by data going to an unknown "X" state.

Solution

To work around this issue, run the simulation without bringing in an SDF file. This issue is scheduled to be fixed in ISE software 12.1.
