A method for reducing a timing violation in a negative slack path from an integrated circuit design, by identifying the negative slack path in the integrated circuit design with a processor, and then identifying positive slack paths by determining timing slack for the paths that are disposed before and after the negative slack path. A prediction is made as to whether margin can be obtained from the positive slack paths by performing additional timing optimization on the positive slack paths, and it is determined whether that margin is sufficient to reduce the timing violation to at least a desired level. If the margin is sufficient, then additional timing optimization is performed on the positive slack paths, and the margin is used to manipulate the clock skew and reduce the timing violation on the negative slack path.

Automated timing optimization

A tool for facilitating automatic test pin assignment for a programmable platform device including a process for collecting information related to the programmable platform device, a process for automatically initializing a test pin assignment for the programmable platform device, a process configured to receive user specifications for IOs and a process for performing dynamic test pin reassignment in response to the user specifications.

System for performing automatic test pin assignment for a programmable device

A method for generating a plurality of timing constraints for a circuit design is disclosed. The method generally includes the steps of (A) identifying a plurality of clock signals by analyzing the circuit design, (B) determining a plurality of relationships among the clock signals and (C) generating the timing constraints for the circuit design in response to the clock signals and the relationships.
