Problem Title:
X2VPREP/TIMENET/TIMENETX:  Error--Incompatible netlist version


Problem Description:
You may get an "Incompatible netlist version" error from X2VPREP or XCDSPREP
if you are processing a design in XACT 5.20 for Verilog simulation, AND:

1.  You use the 9502 or earlier version of the Verilog interface from Cadence
(TIMENET 5.5, which calls XCDSPREP),	OR

2.  You use the TIMENETX script from the ES-Verilog v5.1.1 interface from
Xilinx (TIMENETX calls X2VPREP).

TIMENET 9502 or TIMENETX 9502 will just issue an error about failing to
process the design.


Solution 1:

The problem is that in going from XACT 5.1 to 5.20, the XNF netlist version
changed from 5.0 to 6.0, requiring support for a new netlist reader in X2VPREP.

The interface versions named above do not support XNF 6.0.

The Cadence 9504/9601 release scheduled for end of 1Q96 will add this support.

Currently the ES-Verilog interface on the 5.20 XACT Core Tools CD for Sun and HP

workstations will also support XNF 6.0.  See Chapter 4 of the 5.20 XACT Core Too

Release Document for installation instructions and full documentation of this
interface.
