Parallel maze routing problem

WebDeterministic parallel maze routing Routing regions of nets are highly overlapped − Speedup of parallelization is limited Non-deterministic parallel maze routing − NCTU-gr 2.0[Liu+, TCAD’13], SPRoute [He+, ICCAD’19] − Threads route nets through the same region concurrently Bulk synchronous deterministic maze routing WebTo solve these problems, we propose a novel two-phase maze routing algorithm. This algorithm solves the livelock issue in the net-level parallelism and achieves an 11.0×speedup using 28 threads compared with a state-of-the-art single-threaded global router. • SPRoute 2.0 proposes a detailed-routability-driven technique and a de-terministic ...

WebIn net-level parallelization of maze routing, the livelock problem may result in redundant work and reduce the speedup of parallelization; in the worst case, it may even prevent maze routing from converging. To solve these problems, we propose a novel two-phase maze routing algorithm. WebMay 18, 2012 · Parallelization of VLSI routing algorithms is one of the challenging problems in VLSI physical design. This is due to a large number of nets as well as the shared routing resources that result in data dependency among concurrent tasks.
