SYSTEM AND METHOD FOR IMPLEMENTING AND VALIDATING STAR ROUTING FOR POWER CONNECTIONS AT CHIP LEVEL

摘要

A system, method, and computer program product for automating the design and routing of non-shared one-to-many conductive pathways between a common pad and circuit blocks in an integrated circuit. Such pathways are routinely required for power and signal distribution purposes. Automated scripts perform a star routing methodology and validate the routing results. The methodology processes input width and layer constraints and from-to's denoting start and end points for each route by invoking a star_route command in a router that implements interconnections as specified. Routing results are validated by checking for routing violations, including shared segments and width violations. Violations are marked for correction.

1. A processor-implemented method for automatically creating multiple non-shared one-to-many routed conductive pathways in a circuit design, the method comprising:
using a processor:
for each intended conductive pathway:
creating constraints for the widths and conductive layers allowed for each pathway portion;specifying a from-to denoting a start point and an end point;invoking a computer-operated star router tool to route the intended conductive pathways according to the constraints and the from-to's; andtangibly outputting the routed conductive pathways.
