Quartus II 7.1 - SOPC Builder New Component

Hi

I had the same error and I fixed the problem:

When the sopc refreshes the components list it need to have also the vhd file (not only the tcl) in order to know the ports width.

so:

1. make sure the top level vhdl is in the directory of the project, or if you prefer, in other directory that you added to the project (global or local)

2. in the tcl, second row: "set_module" have to be the exact name of the vhdl entity.

enjoy.
