3.3i NGDAnno - NGDAnno may write out an incorrect SDF file for an X_MUXDDR component.

Description

Keywords: NGDAnno, SDF, MUXDDR, CE, X_MUXDDR

Urgency: Standard

General Description:
NGDAnno may incorrectly write out the delays for X_MUXDDR in the .sdf file:

(CELLTYPE "X_MUXDDR")
(INSTANCE QFDDRRSE\/OUTPUT\/OFF\/OFFDDR)
(DELAY
(ABSOLUTE
)
)

Because there are no PORT delays or IOPATH delays, simulators will error out due to an invalid SDF.

Solution

This problem is fixed in the latest 3.1i Service Pack available at:
http://support.xilinx.com/support/techsup/sw_updates. The first
service pack containing the fix is 3.1i Service Pack 7.
