Auto-generation of AMS behavioral models in different languages from hybrid automata

Abstract

This paper proposes a methodology for automatic generation of behavioral models of analog and mixed signal circuits in different languages from hybrid system based specification. The proposed approach captures the design specification of a class of circuits into a language independent high level library of models. Taking the user input, and the domain knowledge from the specification, and by parsing the library of models, the model generator automatically generates the behavioral models in different languages. In this work, the behavioral models are developed in Verilog-A and SPICE languages, which are often used in industrial applications and are also structurally different. The methodology is explained with a synthetic example of programmable gain amplifier with automatic gain control circuit.
