Abstract
A method for reaching signoff closure in an ECO (engineering change order) process involves the use of violation context data from the signoff tool as the basis for design layout modifications in an implementation tool. The violation context data includes violation information other than violation location/path information. Because the signoff tool, and more specifically, the signoff algorithm used by that tool is the most accurate model of actual IC behavior, the use of violation context data generated by the signoff tool to implement changes to the design layout will generally produce appropriate and effective results. By accessing this violation context data from the signoff tool, an implementation tool need not rely on its less accurate implementation analysis to determine the optimal design layout modifications for correcting violations detected by the signoff tool.
