BLADE: Bi-Level Bayesian Optimization for Metal-Density-Constrained Multi-Layer Package Power/ground Plane Synthesis
DescriptionIn advanced packages, large power/ground (P/G) planes are essential for power integrity but prone to warpage. While a uniform metal-density constraint combats warpage, mandatory degassing holes complicate adherence and degrade IR-drop. We propose BLADE, the first P/G plane synthesis methodology that enforces this constraint while optimizing power integrity. BLADE expands P/G planes from skeletons under metal density control to ensure connectivity, naturally leaving holes for degassing. Guided by a fast IR-drop evaluator, our bi-level Bayesian optimization framework efficiently navigates the design space. Experiments on six SiP cases demonstrate that BLADE satisfies the metal-density constraint and achieves superior IR-drop performance.
