Simulation and Verification

[prink]

Hi,

   I have a problem when I Generate Expected Simulation Results process  For the test bench waveform 

This is  the error  that appears every time,  

Running Fuse ...
ERROR:Simulator:418 - Compilation failed: vhpcomp: The system cannot find the file specified.. 

Can anyone suggest how can I solve this problem?? 

 Thanks :)

Can you elaborate your problem with more details? What ISE version?

What operation did you perform in GUI?

Any more information in fuse.log?

Hi thanka you for replying.

I am using ISE 8.1 version.

I have generated code for a communication transmitter in xilinx. I want to test

the module by simulation. So under behavioral simulation i created a testbench

waveform for the same. After assignin all the inputs I tried to generate the waveform

by I got the above error.

There is no other information available in fuse.log

Kindly help.

Well, 8.1 is a bit old and the waveform testbench is deprecated in the current ISE.

The .tbw will be first converted to an HDL testbench .tfw and used in fuse.

Select the .tbw and double click "View Generated Testbench as HDL". Normally it outputs a .tfw.

You can try renaming it to .v or .vhd and replacing the waveform with this testbench.

Hi,

Thanks for your reply.

As you have mentioned the .tbw file outputs a .tfw file when we select generate waveform. But I couldnt find .tfw file in my directory. There was one .vhw file. I think you mean the same file. I tried converting the file to .vhd file and use it to simulate the waveform. But still the same error persists. should I try upgrading my simulator to ISE 10.1.

Kindly reply

Upgrade the tools to the latest version (13.4, I think).

Forget about drawing waveforms and create a proper VHDL test bench.
