Abstract

This paper describes a layout-aware analog synthesis methodology. The methodology includes parameter exploration and classification, parameter domain pruning and sampling, and identification of parameter dependencies. The optimization process executes a combined constraint transformation, floorplanning and global routing. The paper presents results for a high frequency continuous-time filter, and two ̿Δ ADCs. Compared to similar work, the methodology is more flexible in handling new designs, and more tolerant in accommodating layout parasitics.
