Abstract :
A description is given of ILAC (Interactive Layout of Analog CMOS Circuits), a CAD (computer-aided design) tool that automatically generates geometrical layout for analog CMOS leaf cells from netlist information and user-specified constraints on cell bounds and input/output locations. ILAC is the companion tool of IDAC, a design tool that sizes analog CMOS circuits from a library of proven schematics given a set of functional specifications and technological parameters. Unlike existing analog silicon compilers that use some predefined placement for a specific type of circuit, ILAC determines an optimal layout for any circuit and any set of input parameters
