Warnings on files generated by Platform Designer (QSys)

My (pretty much Cyclone5 SoC GHRD) project is producing almost 700 warnings. Majority of the warnings originates from files automatically generated by Platform Designer as a result of the integration...

    Hi,


    This is due to the different name connected to the top level file. For example,

    ...

    .hps_0_hps_io_hps_io_gpio_inst_GPIO44 (hps_gpio_GPIO44),

    ..

    In this case, you can either modify the sdc file to match the top level port name or modify the top level port name to match the name in the SDC file.


    Thanks

    Best regards,

    KhaiY

@KhaiChein_Y_Intel Thank you very much.
You are right the top level names were different. These were created meaningful like the "HPS_LED" below.

.hps_0_hps_io_hps_io_gpio_inst_GPIO53 ( HPS_LED )

I was on a wrong path chasing down the port names (hps_0_hps_io_hps_io_gpio_inst_GPIO53) since these were similar to the names in the SDC file.
That was - in part - due to the fact that these names have multiple times repeated prefix "hps_io_" and that seemed to be the difference - until I figured out that it is the "HPS"LED" what counts.

Still puzzled why:
- The auto-generated SDC uses different names than desired

- Platform Designer generates port names with numerous repetitive prefixes. Tried to see how to control this and didn't find it.

Thanks!
