ABSTRACT:
The present invention is for a computerized standard cell library with inter alia standard cells having high metal layer intra cell signal wiring for use in designing ICs in accordance with a standard cell IC design methodology. High metal layer intra cell signal wiring in accordance with the present invention arises to wire segments in an IC's high interconnect metal layer exclusively reserved for horizontal wire segments being constrained to a limited number of horizontal routing tracks, thereby leaving the remaining horizontal routing tracks unimpeded for inter cell signal wiring purposes.
