740 - Lattice ispLEVER: Timing Analysis: What is the I/O Timing Report?
Lattice ispLEVER: Timing Analysis: The I/O Timing Report (.ior) is a used to report the IO timing analysis of your design. Input Setup and Hold times (Tsu, Th) and Clock-to-Output times (Tco) are reported. The IO Timing Report sweeps across all the speed grades to determine the worst case values.
To generate the I/O Timing Report in Lattice Diamond software, right click the 'I/O Timing Analysis' box in the Process pane and select 'run'. Mark the Checkbox to run the report automatically each time PAR is run.
