| CAUSE: | In a design file, the dedicated clock feeds the specified I/O pin, which in turn feeds other peripheral logic in both positive and negative polarities. However, this cannot be implemented in the current device. If the non-peripheral register is packed to an I/O cell, the specified I/O pin which is fed by a dedicated clock will feed the clock signals for other I/O cells clock signals with both true and complement polarity. |
| ACTION: | Make sure the dedicated clock signal feeds I/O cells in one polarity only. |
