Processing a circuit design includes stabilizing the circuit design by a design tool that performs one or more iterations of implementation, optimization assessment, optimization, and stability assessment until a threshold stability level is achieved. The design tool determines, in response to satisfaction of the threshold stability level, different strategies based on features of the circuit design and likelihood that use of the strategies would improve timing. Each strategy includes parameter settings for the design tool. The design tool executes multiple implementation flows using different sets of strategies to generate alternative implementations. One implementation of the alternative implementations nearest to satisfying a timing requirement is selected. The selected implementation is iteratively optimized to satisfy the timing requirement, while restricting changes to placement of cells and nets on a critical path of the one implementation to less than a threshold portion of cells and nets on the critical path.

Automated timing closure on circuit designs

Disclosed approaches for guiding actions in processing a circuit design include a design tool identifying first violations of design checks and determining severity levels of the first violations. The design tool determines for each violation, suggested actions associated with the violation and presents on a display, first data indicative of the suggested actions in order of the severity levels of the first violations. The first data include selectable objects, and each selectable object has an associated executable procedure. The design tool can execute the procedure associated with one of the selectable objects in response to selection and modify the circuit design in response to execution of the procedure.
