Abstract
A system and method perform global routing during integrated circuit fabrication. The method includes performing a design change in a portion of an integrated circuit design using a processor, determining whether the design change requires rerouting, and requesting a global routing lock based on determining that the design change requires the rerouting. The method also includes a router providing control of the global routing lock to one of two or more of the threads that request the global routing lock, and performing global routing for all of the two or more of the threads in parallel. A physical implementation of the integrated circuit design is obtained.
