All circuits come from ITC 2017 AMS Benchmark Circuits V2.2, IEEE Standards Association. There are three circuits so far, including an OP-AMP circuit, a PLL circuit, and an OSC circuit. Their schematics are listed in 'schematics.pdf'. There are 14, 36, and 77 independent variables corresponding to the OSC, OPA-MP, and PLL circuits. Most of them are the width and length of the MOSFET. The return of the evaluation function is the FOM value defined in the netlists, which is also called the Objective Function in optimization problems.

Download and unzip all directories to your main project directory, before importing in your code, please set the variables below correctly:
path_param = 'PATH/TO/param'
path_simlog = 'PATH/TO/simlog'# or 'PATH/TO/xxx.lis'
sim_command = 'system simulation command '
The variables above are defined in Python scripts. _pathparam is the path to the param file, _pathsimlog is the path to the simulation output file, and _simcommand is the system command used to simulate the netlist with simulators.
To import in your algorithm code, add "from circuit/circuit.py import circuitXX" ahead of your main function code.
