The Zynq 7Z010 device has 54 High Range I/O ports.
The IP example design has up to 56 I/O ports, depending on the IP configuration.
When implementing the SEM IP with the provided example design for a 7Z010 device, the following DRC error may arise:
ERROR: [Drc 23-20] Rule violation (IOCNT-2) Number of HP/HR IOs - The design contains 56 unplaced High Range-only I/O ports while the target device, xa7z010clg225-1Q, has 54 remaining
User will need to remove some of the IP's example ports from connecting I/O for the example design to fit in the target device. For this small device it is more reasonable to use post-crc functionality than SEM IP.
This is not an IP issue, but instead a limitation of the device with respect to I/O pin count.
