M1.4 Map - Optimization of OFDT symbol results in dangling tri-state control pin


In a case where OFDT has both data and tri-state control
pins grounded, map optimizes the OFDT down to a buffer
driven by GND. The tri-state control pin is incorrectly
left configured with no driver. This results in the following
drc error:

WARNING:x4kdr:82 - Blockcheck: The pin "T" on comp (mapped
physical logic cell)"SRAM1_ADD<16>" is configured to be used
but has no signal attached to it.


This issue is fixed by the latest M1.4 Core Tools patch
which is available in the XILINX Download Area:
