  • Patent number: 11301614
    Abstract: An existing design of an integrated circuit includes existing cells that have already been placed and routed. An engineering change order (ECO) specifies additional new cells (ECO cells) to be inserted into the existing design. The ECO cells are also associated with target locations for their placement among the existing cells, but these target locations may violate design rules. The feasibility of “legalizing” the placement of the ECO cells within the existing design is assessed as follows. The ECO cells are clustered into clusters based on their target locations. Clusters are assessed by determining an ECO placement impact (EPI) index for individual clusters. The EPI index is a measure of the feasibility for legalizing the placement of the ECO cells in that cluster.

  • Patent number: 10878166
    Abstract: Techniques and systems for inserting repeaters in an integrated circuit (IC) design are described. Some embodiments can place a snapping region in the IC design, wherein the snapping region includes a predetermined arrangement of feasible grid regions and blocked grid regions, and wherein repeaters are allowed to be placed in feasible grid regions but not in blocked grid regions. Next, the embodiments can iteratively perform a set of operations, comprising: selecting a net from a set of nets; determining an initial location for inserting a repeater in the net; identifying an unoccupied feasible grid region in the first snapping region that is closest to the initial location; and inserting a repeater in the net in the unoccupied feasible grid region.
