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

描述

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.

service pack containing the fix is 3.1i Service Pack 7.
