Problem Title:
CONCEPT2XNF 5.0: Does not translate Slew_rate=fast attribute


Problem Description:
PLATFORM(s): Sun, HP

The SLEW_RATE=FAST attribute may not be translated by Concept2xnf 5.0.	This
will be evident when you look at the section in the .rpt file produced by
XMAKE documenting the slew rate setting of the outputs in your design.

A typographical error in the concept2xnf.prop file causes CONCEPT2XNF to
process this attribute incorrectly.



Solution 1:

Edit the concept2xnf.prop file in the install_dir/share/library/xilinx/data dire
ctory.

On the line that reads,

	SLEW_RATE

Add a ":" at the end of "SLEW_RATE":

	SLEW_RATE:

The property should be attached to the output buffer (properties are not
supported on Concept PADs).

Patches available on the Cadence FTP site and also on the Cadence Sourcelink
web site were supposed to fix this bug:

    xilNetlistEx05.00-s003sun4.t.Z,
and xilNetlistEx05.00-s004sun4.t.Z;

however, the patches were missing the correction described above.
