A tool for the integration of new VHDL-AMS models in SPICE

In this work we describe a tool for VHDL-AMS modeling within SPICE based simulators. The user can write new SPICE models using VHDL-AMS standard, the proposed tool will automatically build the code to be embedded inside the SPICE simulator. A Smart Power band-gap reference voltage circuit and a recipe to build an advanced MOS model are presented as examples to demonstrate the effectiveness of our approach.
