Rectilinear Steiner Minimum Tree (RSMT) is the shortest way to interconnect a net’s n pins using rectilinear edges only. Constructing the optimal RSMT is NP-com

The rectilinear Steiner tree problem, minimum rectilinear Steiner tree problem (MRST), or rectilinear Steiner minimum tree problem (RSMT) is a variant of the geometric Steiner tree problem in the plane, in which the Euclidean distance is replaced with the rectilinear distance.

In this work, we analyze the approximation errors of HPWL model, and theoretically prove the effectiveness of the RSMT-based wirelength model. Moreover, we propose the first differentiable RSMT wirelength model based on the classic RSMT algorithm, which is integrated into the state-of-the-art analytical placer.

2011年2月28日 · I. Introduction FLUTE is a very fast and accurate technique for rectilinear Steiner minimal tree (RSMT) construction. There is a user-defined parameter to control the tradeoff between accuracy and runtime. FLUTE is optimal and extremely fast for nets up to degree 9. For higher degree nets, it is still very fast and accurate.
