FPGA Express: Verilog keyword "tri" causes Express to crash (Cannot create chip in Synopsys project) (Abort at 470)


Record #6013

Product Family: Software

Product Line: Synopsys

Product Part: FPGA Express

Product Version: 3.1

Problem Title:
FPGA Express: Verilog keyword "tri" causes Express to crash (Cannot create chip in Synopsys project) (Abort at 470)



Problem Description:
Urgency: Standard

General Desciption: When analyzing a Verilog design in Foundation Express 2.1i, the following message may occur:

Pcm: Cannot analyze file in Synopsys project- Unknown error
Pcm: Cannot get file's status from Synopsys- Synopsys software caused unexpected exception Pcm: Cannot get information count- Synopsys software caused unexpected exception


A second error possibility is "Abort at 470".


Solution 1:

If the code contains the keyword "tri", replace each instance with "wire".
This replacement makes no difference in synthesis and does not cause the FPGA Express tools to crash.
