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. In this paper, VLSI Maze routing using GPGPU has been proposed to enable runtime performance improvement. … thompson masonry nebraska

WebThe SIMD systems account for the intrinsic data parallelism in maze routing. The primary idea is to use an N x N array of identical processing elements that have a one-to-one correspondence with the N x grid plane and so achieve a linear runtime for finding a path. WebThe Routing-Tree Problem ․Problem: Given a set of pins of a net, interconnect the pins by a “routing tree.” ․Minimum Rectilinear Steiner Tree (MRST) Problem: Given n points in the plane, find a minimum-length tree of rectilinear edges which connects the points. ․MRST(P) = MST(P ∪S), where P and S are the sets of original WebNov 4, 2024 · Maze routing is usually the most time-consuming step in global routing or detailed routing. One possible way to accelerate it is to use parallel computing. Net … thompson masonry sealer
