Follow the timing guidelines and examples to ensure that the Timing Analyzer analyzes the I/O timing correctly.
- To perform proper timing analysis for the I/O interface paths, specify the system level constraints of the data pins against the system clock pin in the .sdc file.
- To perform proper timing analysis for the core interface paths, define these clock settings in the .sdc file:
- Clock to the core registers
- Clock to the I/O registers for the simple register and DDIO modes
