Modelsim Error: file in read mode

file in read mode

The path is correct. I recreate the project and success to compile the file d. Thanks

Maybe your file (source code) didn't have any permission to read by the tool or the file doesn't exist? Maybe the path is wrong?

In the absence of more details of your problem, here is my guess: Your test bench is probably using a file to read and it cannot find file in the project directory. Either you should put the specified file in the project directory or specify its entire path in the testbench program.
