The following relates generally to analog circuit re-design. Some embodiments identify a candidate component of the circuit by determining that if the candidate component is adjusted or replaced, the circuit will satisfy a requirement metric. In some implementations, an optimization problem or Bayesian reasoning may be used to change parameters of the candidate component to create a replacement component. In some implementations, a replacement component of a different type than the candidate component may be selected by solving a mixed-integer optimization program or by using a non-linear program with continuous parameters.
