Recent advances in auto-generating analog and mixed-signal (AMS) circuits use standard digital tool flows to compose AMS circuits from a combination of digital standard cells and a set of auxiliary cells (auxcells). Until now, generating auxcell layouts for each new PDK was the last manual step in the flow for auto-generating AMS components, which limited the available auxcells and reduced the optimality of the auto-generated AMS designs. To solve this, we propose AuxcellGen, a framework to auto-generate auxcell layouts and performance models. Aux-cellGen generates a parasitic-aware auxcell performance model using a neural network (NN), auto-sizes and optimizes auxcell schematics for a given design target, and auto-generates auxcell layouts. The framework is demonstrated by auto-generating tristate buffer auxcells for PLLs and sense-amplifier auxcells for SRAM across a range of user specifications that are compatible with standard cell and memory bitcell pitch.
