  • System and method for implementing and validating star routing for power connections at chip level
    Patent number: 10210301
    Abstract: 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.
