[Place 30-415] IO Placement failed due to overutilization. This design contains 46528 I/O ports
while the target device: 7z045 package: ffg900, contains only 492 available user I/O. The target device has 492 usable I/O pins of which 0 are already occupied by user-locked I/Os.
To rectify this issue:
1. Ensure you are targeting the correct device and package. Select a larger device or different package if necessary.
2. Check the top-level ports of the design to ensure the correct number of ports are specified.
3. Consider design changes to reduce the number of I/Os necessary.
