    Hi,


    Inside the testbench myProject_tb_1.v, make sure the module name also myProject_tb_1.

Hi,

From your hint I compared my successful test bench myProject_tb.v with myProject_tb_1.v and found following difference:

myProject_tb.v: module myProject_tb ;

myProject_tb_1.v: \module myProject_tb_1.v ;

After editing in myProject_tb_1.v: \module myProject_tb_1.v to module myProject_tb_1

and compiling again it works

It is essential that after changing the name of the test bench the design shall be compiled!

Nevertheless, I find it astonishing that modelsim generated a faulty myProject_tb_1.v. Well, now I will check every new test bench file.

Thank you very much. I appreciate your excellent support.

With best regards
