Novel Grid-Based Power Routing Scheme for Regular Controllable-Polarity FET Arrangements

Polarity-controllable transistors have emerged in the last few years as an adequate successor of current CMOS FinFETs. Due to the additional polarity terminal, novel physical design techniques are required. We present a novel grid-based power routing scheme able to mitigate the polarity terminal impact. The logic cells are organized in regular arrangements and easily configured using the novel power routing scheme. The impact of the placement and routing techniques used is gauged in terms of routing metal distribution, speed and area performance. Benchmark circuits are synthesized, placed and routed using commercial tools and performances are extracted. Post place and route results show 28% faster circuits compared to 22nm FinFET regular layout-based designs.
