Run C/RTL co-simulation failed

[feng86]

Hi,

Run C simulation and C synthesis is OK. But when I run C/RTL co-simulation encountered with the following errors.

Generating cosim.tv.exe

Anyone know how to fix it? Please help me! Thanks! 

I've attached the protject files.

hi @feng86

your script / project includes the file main.c as source file for the files to synthesize; however it is your TB.

could that be the issue?

i tested your source files as-is with 2015.3 (not .4 yet .. i have a small harddrive ... ) the same cosim issue doesn't happen but it seems it gets stuck.

i cannot do more than that at the moment; EDIT : maybe you could try tp start the project from fresh as well?

Also i think you should put the "source" directory outside the VHLS project diretory in case it is reset or deleted

Thanks for your suggestion.

Maybe I found where is the problem. I have installed MinGW compiler and the file of MinGW compiler automatically added into "Includes" .When I recovery my computer to the status before install MinGW compiler, then the C/RTL co-simulation passed.

I just met the same problem with you. After trying your way and uninstalling minGW , I have solved this problem. Thank you!
