Use the following combinations for min delay analysis:
- source clock (Slow_min), datapath (Slow_min), destination clock (Slow_max)
- source clock (Fast_min), datapath (Fast_min), destination clock (Fast_max)
Important:
- Delays from different corners are never mixed on the same path when calculating slack.
- Most setup or recovery violations occur with slow corner delays.
- Most hold or removal violations occur with fast corner delays. However, because this is not always true, especially for I/O timing, AMD recommends performing both max and min delay analyses on both corners.
