1. **研究主题**:基于多智能体强化学习(MARL)的SoC多电源域去耦电容(Decap)布局优化算法,解决多电源域同时优化的挑战。 2. **核心方法**: - 每个SoC电源引脚作为独立智能体,采用无状态Q-learning优化Decap布局。 - 结合遗传算法(GA)优化Decap值与数量,并通过RL动态调整GA的变异概率(V3版本)。 3. **关键数据**: - 实际案例:36电源域(480引脚)、93个目标阻抗,30分钟内优化至87个Decap(0201/0402/0603封装)。 - 对比测试:GA V3版本仅用1小时完成100引脚优化,较传统GA(3小时)效率提升显著。 4. **工具集成**:支持输入.spd文件(Cadence Power SI),输出.xlsx或.spd文件,无缝嵌入现有设计流程。
