This is the original version of this post, first published on 21 April 2026 and kept unchanged below. The current version is Two-Stage Cascode Class-AB RF Power Amplifier: Placement & Routing.

Placement of GaN on SiC 2 stage RF AMP

original , fixed (hardcoded), SA 1, QP, QP+SA (MNA, Small WireLen, non 0 viol.), 

• QP+SA with adaptive cooling schedule (2.55 WireLen, usual. 0 viol.) 
• add congestion penalty in energy (track overflow significantly reduced,  Bench, Overflow Comp, viz, detail viz)

QP+ILP+PrePass (No A* or SA, viol.) comparison with ACS  detail

Slides fit of SA for RF PA Layout

RDP or not
