For my current project, I am using Modelsim 5.7c for simulation purposes. I am also using Xilinx ISE 5.2 as a design environment.
Yesterday I have compiled Xilinx's libararies (unisim_ver, xilinxcorelib_ver ...etc) and then mapped them. But when I simulate my code, after compilation and linking to the compiled libraries, Modelsim quits without any warning/errors.
Has any one got explanation or solution suggestions for this problem?
Check if the command you are giving is something like
vsim <top_module> glbl
If you dont simulate glbl while using xilinx core libraries, Modelsim sometimes closes without any errors
Which system are you using? I had this problem once in my WIN2000. Try this. Delete these 2 files in \WINNT directory "mti_ent" and "mti_ent2".
It worked for me.
