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".

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.
