Multi-threaded network routing for circuit design
A recently granted patent (Publication Number: US11928500B1) discloses a method and device for efficiently routing networks in a circuit design. The method involves accessing circuit design data, generating a tree data structure by partitioning and grouping networks, and routing the networks using multiple threads based on the tree structure. The process includes determining initial bounding boxes, partition lines, and moving networks between groups based on certain conditions. Additionally, the method iteratively partitions groups of networks based on thresholds and conditions, ensuring efficient routing of the networks.
The device described in the patent includes a hardware processor and memory storing instructions to generate the tree data structure and perform network routing. Similar to the method, the device iteratively partitions and groups networks, determines thresholds for grouping, and efficiently routes networks using multiple threads. The device's operations involve identifying groupings of networks, determining conditions for further partitioning, and moving networks between groups based on partition lines. By utilizing a tree data structure and multiple threads, the device ensures effective routing of networks in a circuit design, enhancing overall efficiency and performance in network routing processes.
