Abstract: Disclosed are methods, systems, and articles of manufacture for characterizing an electronic design with an MOR-based envelope Fourier technique. Multiple training models may be determined at multiple time points for an electronic circuit by using at least the MOR-based envelope Fourier technique that comprises a harmonic balance technique. A training model of the multiple training models may be reduced into a reduced order training model in a reduced order space at least by applying at least model order reduction of the MOR-based envelope Fourier technique to the training model. A time varying system may be determined for the electronic circuit based by using at least the reduced order training model.
