- Launch edge
- The active edge of the source (launch) clock that launches the data.
- Capture edge
- The active edge of the destination (capture) clock that captures the data.
- Source clock
- Also called the launch clock.
- Destination clock
- Also called the capture clock.
- Setup requirement
- The timing relationship between the launch edge and capture edge that defines the most restrictive setup constraint.
- Setup relationship
- The setup check verified by the timing analysis tool.
- Hold requirement
- The timing relationship between the launch edge and capture edge that defines the most restrictive hold constraint.
- Hold relationship
- The hold check verified by the timing analysis tool.
