Macro Placement

Routing congestion in VLSI explained for physical design engineers: how global routers measure GCell capacity, demand and overflow, cell density vs pin density, global, local and layer congestion, floorplan, logic and placement causes, fixes with halos, partial blockages and cell padding, the timing impact, a debugging flowchart and interview Q&As.

Macro Placement Guidelines After pin placement, the next crucial step in physical design is macro placement. Proper macro placement ensures optimal routing, reduces congestion, and improves timing. Below are essential guidelines for macro placement that, if followed carefully, can help in handling complex blocks with ease. Formula for Macro Spacing Before placing macros, you can […]
