Answers Database X2VPREP/TIMENET/TIMENETX: Error--Incompatible netlist version Record #736 Product Family: Software Product Line: Cadence Product Part: x2vprep Product Version: 9502 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 Tools Release Document for installation instructions and full documentation of this interface. End of Record #736 - Last Modified: 01/14/97 13:31
