Abstract : Transistor placement is the key step to dominate the quality of standard cell layouts because of the limited routing resource of cell layouts. A routability-aware transistor placement algorithm can then help generate high-quality transistor placements favoring cell routing to reduce potential rule violation and layout quality as well. In this paper we propose aroutability- aware dynamic programming (DP)–based transistor placement algorithm that can efficiently generate transistor placements favoring cell routing and considering diffusion shape constraints. Then, a LEGO-liked assembling method considers the issue of different folding styles to generate transistor placements of high-driving cells. Our results show that the proposed methods can have dramatic routability and runtime improvement compared to existing works. Indexterms - Standard cell, Transistor placement, Dynamic programming (DP), LEGO.
