1.6.1.1. Create the ALTDDIO_BIDIR IP Core
Follow these steps to create the ALTDDIO_BIDIR IP core.
- Unzip the ALTDDIO_DesignExample_ex2.zip file to any working directory on your PC.
- In the Intel® Quartus® Prime software, open the ex2.qar project .
- In the IP catalog, double-click ALTDDIO_BIDIR .
- Specify the IP variation file name and click OK.
- In the parameter editor pages, select or verify the configuration settings shown in the following table. Click Next to advance from one page to the next.
Parameter Editor Page Parameter Value 2a Which megafunction would you like to customize In the I/O folder, select ALTDDIO_BIDIR Which device family will you be using?
