6.1.3.1. Guideline: Swap datain_h and datain_l Ports in Migrated IP
When you migrate your GPIO IP from previous devices to the GPIO IP, you can turn on Use legacy top-level port names option in the GPIO IP parameter editor. However, the behavior of these ports in the GPIO IP is different than in the IP used for the Stratix® V, Arria® V, and Cyclone® V devices.
The GPIO IP drives these ports to the output registers on these clock edges:
- datain_h—on the falling edge of outclock
- datain_l—on the rising edge of outclock
If you migrated your GPIO IP from Stratix® V, Arria® V, and Cyclone® V devices, swap the datain_h and datain_l ports when you instantiate the IP generated by the GPIO IP.
