EFFICIENT EXHAUSTIVE PATH-BASED STATIC TIMING ANALYSIS USING A FAST ESTIMATION TECHNIQUE |
摘要 |
Techniques and systems are described for performing efficient path-based static timing analysis (STA) in a circuit design. During operation, the system identifies a set of paths within the circuit design, wherein each path includes one or more segments. For a path in the set of paths, the system determines if at least one segment in the path is shared with a different path which was previously computed by performing a path-based STA, wherein the at least one segment in the different path is associated with previously computed path-based timing information. If so, the system then performs an estimation of a path-based delay for the path based at least on the path-based timing information associated with the shared segment in the different path. Otherwise, the system computes a path-based delay for the path by performing a path-based STA on the path. |
