4.6.1. Migrating Your ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, and ALTIOBUF IP Cores

To migrate your ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, and ALTIOBUF IP cores to the GPIO Intel® FPGA IP IP core, follow these steps:

  1. Open your ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, or ALTIOBUF IP core in the IP Parameter Editor.
  2. In the Currently selected device family, select Stratix 10.
  3. Click Finish to open the GPIO IP Parameter Editor.
    The IP Parameter Editor configures the GPIO IP core settings similar to the ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, or ALTIOBUF core settings.
  4. If there are any incompatible settings between the two, select new supported settings.
  5. Click Finish to regenerate the IP core.
  6. Replace your ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, or ALTIOBUF IP core instantiation in RTL with the GPIO IP core.
Note: The GPIO IP core port names may not match the ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, or ALTIOBUF IP core port names. Therefore, simply changing the IP core name in the instantiation may not be sufficient.
