Abstract

A description is given of the structure and use of the ADOPT (analog design via optimization) system. The ADOPT system consists of the circuit simulation program HSPICE (Honeywell's version of SPICE), the nonlinear optimization program SUXES-10 (licensed from Meta-Software), and an interface routine called OPTLINK to link the two programs. OPTLINK is set up to pass design parameters and simulation results between SUXES-10 and HSPICE. SUXES-10 passes the initial parameter guess vector to HSPICE. HSPICE then uses these parameters to calculate the desired circuit responses to be optimized and passes the data to SUXES, using PRINT statements. These data are compared to the desired response data and SUXES-10 determines a new set of design parameters to reduce the difference between the two responses. This process continues until SUXES-10 terminates the optimization process.
