Timing Path Definition
The timing path is defined as the path between the start point and the endpoint. All input ports or clock pins of a sequential element are considered valid start points. All output port or D pin of the sequential element is considered as Endpoint.
Ways to fix the Timing Path
- Use of macros. #
- Logic optimization.
- The pipeline can be enhanced.
- Placement of logic launch flip-flop.
- Use Low power trade-off techniques.
- Replicate drivers and split the number of receiving gates.
- Use one hot encoding register, that will increase the speed of operation.
- Divide large serial operations into multiple smaller-length parallel operations.
Is the term clock skew and global skew the same?
No, the links between the clock skew and the global skew are different. The global skew refers to the difference in skew between two flip-flops that cannot be related via fan-in or fan-out. Global skew is the skew between two independent flip-flops, whereas clock skew is the skew between two dependent flip-flops. #
What is Clock Latency?
when the clock arrives at the pin at a different time than the source. Source latency and network latency are further subdivided. Source latency describes the propagation time from the clock source to the clock port, whereas network latency assesses how quickly the network is operating. #
What is a false path in static timing analysis?
A path that doesn’t need to be optimized during time analysis is referred to as a false path. It implies that a task need not be launched and completed in the same clock cycle. It’s referred to as a mistaken path. The timing optimization tool does not optimize it. #
