Timing path:Timing paths in a design can be considered as a collection of paths. Each path has astartpointand anendpoint. In STA, the paths are timed based on validstartpointsand validendpoints. Validstartpointsare input ports and clock pins of synchronous devices, such as flip-f...
The evaluation and prediction of timing performance of a VLSI design is traditionally based on the identification and evaluation of the critical paths. The paper demonstrates that existing methodologies of identification of the critical paths are deficient because they do not take into consideration many...
What are the different Timing paths How to model clock skew and clock transition time How to constrain different timing paths Concept of virtual clock Concept of time budgeting How to constrain the input and output of a single clock design in different scenarios Input delay: Falling clock edge ...
Identify all the timing paths in a circuit Requirements No, But a basic knowledge in Digital Electronics will help! Description Want to become a chip design engineer? Then, STA is mandatory for you! Welcome to my course on ‘Static Timing Analysis on VLSI Circuits’ ...

STA breaks a design down into timing paths, calculates the signal propagation delay along each path, and checks for violations of timing constraints inside the design and at the input/output interface. timing path 存在 start and end point, 定义分别如下: ...
A High-Performance Timing Analysis Tool for VLSI Systems Why OpenTimer? OpenTimer is a newstatic timing analysis (STA)tool to help IC designers quickly verify the circuit timing. It is developed completely from the ground up usingC++17to efficiently support parallel and incremental timing. Key feat...
