Hi,

Sorry for the delay. I have been out of office for the past week. Regarding your latest compilation error, it seems like the default built in library which suppose to be to available in the Modelsim Intel FPGA Edition could not be found during the compilation ie altera_mf.

I am not sure why your compilation is unable to locate these libraries but as a workaround, you can force compile all these libraries to your local folder. You can do the following in msim_setup.tcl:

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

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

Best regards,

Chee Pin
