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


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.


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 Tools
Release Document for installation instructions and full documentation of this
