Title: GCD fill layer in 28nm technology
Post by vlsi_design on Jul 24^th, 2022, 6:55pm

Hi, In addition to active, poly and metal fill layers, do I need to do GCD fill layer for a typical 28nm cmos technology? The kit documents do not clearly explain it. What are the additional fill layers needed a typical 28nm cmos technology?

Can you clarify what is the GCD layer, please? Generally dummy fill rule deck will generate all necessary fill layers for a given design.
