Bug report: Quartus will not load correct library in VHDL

Thank you replies.

> Is the --synthesis library directive per file or per module?

I have used the directive per module.

> Synthesis directives are not part of VHDL,...

I have thought that the directives should part of VHDL (like C), and not defined the synthesis directives in the IEEE's.

I have zipped the project and uploaded to the dropbox.

https://www.dropbox.com/s/q59tmjjrjj70img/vhdlproject.zip?dl=0

First Step, open the unzipped project, and compile (Ctrl+L).

Second, modify main.vhd s/my_lib/my_lib2/ at line 29, 30, and save (Ctrl+S).

Finally, re-compile (Ctrl+L).

Then, open it in RTL-Viewer, open calc:i0 node, you will see it contains additive module.

But mylib2::calc (in lib.vhd) uses multiply...

Next Step, Menu -> Project -> Clean Project... to clean-up the project, then, re-compile (Ctrl+L).

Now you will see calc:i0 contains a multiplicative module in RTL-Viewer.
