Rutenbar | 视频video | | 图书封面 |  | 描述 | Cell-based design methodologies have dominated layout generation of digital circuits. Unfortunately, the growing demands for transparent process portability, increased performance, and low-level device sizing for timing/power are poorly handled in a fixed cell library. .Direct Transistor-Level Layout For Digital Blocks. proposes a direct transistor-level layout approach for small blocks of custom digital logic as an alternative that better accommodates demands for device-level flexibility. This approach captures essential shape-level optimizations, yet scales easily to netlists with thousands of devices, and incorporates timing optimization during layout. The key idea is early identification of essential diffusion-merged MOS device groups, and their preservation in an uncommitted geometric form until the very end of detailed placement. Roughly speaking, essential groups are extracted early from the transistor-level netlist, placed globally, optimized locally, and then finally committed each to a specific shape-level form while concurrently optimizing for both density and routability. .The essential flaw in prior efforts is an over-reliance on geometric assumptions from large-scale | 出版日期 | Book 2004 | 关键词 | Computer-Aided Design (CAD); Layout; Transistor; algorithms; circuit design; logic; optimization | 版次 | 1 | doi | https://doi.org/10.1007/b117054 | isbn_softcover | 978-1-4757-7951-6 | isbn_ebook | 978-1-4020-8063-0 | copyright | Springer Science+Business Media New York 2004 |
