新的AI方法可更早预测电路时序错误,性能优于STA

研究人员开发了一种名为STEP-KD(Sequential Timing Evaluation via Progressive Knowledge Distillation)的新方法,用于改进集成电路设计中的早期时序预测。该方法利用中间设计阶段作为知识转移的垫脚石,逐步将后布线、后布局和后规划模型的信息蒸馏到一个后综合学生模型中。实验表明,与直接蒸馏、监督基线和行业标准静态时序分析(STA)工具相比,STEP-KD显著降低了时序预测误差,总负时序裕度(Total Negative Slack)预测误差率为19.78%,而STA的误差率为74.84%。这项进展旨在在设计过程的早期识别时序问题,从而避免代价高昂的后期重新设计。 AI

影响 通过在早期检测关键时序问题,该方法有望显著减少设计迭代次数,加速半导体行业的产品发布。
