1. A system for generating behavioral models for analog circuits, the system comprising: a computing system with one or more processors and memory storing a program of instructions; a database configured to store a parameterized hardware description language model of an analog circuit and an analog circuit simulator template of the analog circuit; a user interface module configured to receive data for an instance of the analog circuit in a schematic format; an analog circuit simulator implemented on the computing system and configured to use the received data and the analog circuit simulator template to generate a value for a parameter of the parameterized hardware description language model of the analog circuit; and a model constructor implemented on the computing system and configured to generate a behavioral hardware description language model of the instance of the analog circuit based on the parameterized hardware description language model of the analog circuit and the generated value.
