Hi,

Thanks for sharing the msim_setup.tcl. I notice that you have commented all the libraries compilation related lines in the msim_setup.tcl. Sorry for any confiusion, please try to comment out only the following lines as in one of my previous notes:

1. Change "QUARTUS_INSTALL_DIR" to your local Quartus installation folder at line 114

2. Comment out "if ![ string match "*ModelSim ALTERA*" [ vsim -version ] ] {" at line 145 and its corresponding "}" at line 178

3. Commen out "if ![ string match "*ModelSim ALTERA*" [ vsim -version ] ] {" at line 186 and its corresponding "}" at line 215

Only 5 lines 114, 145, 178, 186 and 215 are to be commented out.

Please let me know if there is any concern. Thank you.

Thank you.
