Top level hierarchy wiring via 1×N compiler |
摘要 |
Embodiments that route 1×N building blocks using higher-level wiring information for a 1×N compiler are disclosed. Some embodiments comprise determining higher-level coordinates for a blockage of a 1×N building block, determining intra-1×N coordinates for a shape of the blockage via the higher-level coordinates, and creating routes of intra-1×N wires of the 1×N building block that avoid the intra-1×N coordinates. Further embodiments comprise an apparatus having a higher-level wiring examiner to examine higher-level wiring of an area near a 1×N building block of a physical design representation. The apparatus may also have a blockage determiner to determine a blockage that affects intra-1×N wiring for the 1×N building block and a coordinate calculator to calculate coordinates of a shape of the blockage, wherein the calculated coordinates may enable a routing tool to avoid the shape when creating intra-1×N wiring for the 1×N building block.
