摘要
Abstract
As integrated circuit technology approaches its physical limits,carbon-based electronic devices,with their high carrier mobility,emerge as a crucial pathway for overcoming the bottlenecks of silicon-based technology.However,the existing PKUCNTFET process platform remains immature and exhibits significant differences in design rules compared to traditional silicon-based processes.Conse-quently,conventional silicon-based SRAM compilers cannot be directly adapted.Since SRAM is a critical component of processors,its development in laboratory settings currently relies solely on manual design,hindering the advancement and application of carbon-based processors and memory.This paper presents the first reconfigurable SRAM compiler specifically designed for carbon-based technology.It employs fully customized cell designs and a modular architecture(parameter parsing →circuit generation →layout output).Utilizing the Hanan grid algorithm for multilayer interconnect optimization,combined with A*search and via collision detection to reduce rou-ting latency,the compiler achieves fully automated design flow,resolving core challenges in carbon-based process adaptation and multi-mode configuration.The experimental results demonstrate that the generated SRAM arrays successfully pass LVS/DRC verification.The compiler supports three operating modes:single-port read/write(1RW),dual-port synchronous read/write(2R2W),and one-read-one-write(1R1W),and can generate SRAM arrays with configurable widths(8～256 bit)and depths(64～4 096 words).It also enables automated Liberty timing characterization across 27 PVT corners.This work provides a self-controllable domestic memory solu-tion for the laboratory development of carbon-based integrated circuits.关键词
