Error (12002): Port "X" does not exist in macrofunction "Y"

Question

I added i2c_opencores IP to Qsys like I did before.

The scl and sda are exported as conduits.

However, now I get this message in Quartus (similar for sda):

Error (12002): Port "i2c_opencores_0_export_scl_pad_io" does not exist in macrofunction "q_sys_inst"

The error is caused by this line in the Qsys instantiation in the Verlog file:

.i2c_opencores_0_export_scl_pad_io (PMODA_IO[2]),

I checked:

- Qsys instantiation template: .i2c_opencores_0_export_scl_pad_io is there

- bsf-file: no i2c_opencores_0_export_scl_pad_io there, while it was in

a previous version.

Any clues?

Thanks,

Jos

I will answer my own question. Because I used a previous project

as basis for the project in which the error occurred I got two

Qsys output folders with different names. This confused Quartus,

apparently. Removing the oldest folder solved the problem.
