Abstract

The implementation of a VHDL-AMS to SPICE converter(Vhdl2Spice) to be inserted in a complete CAD environment [1] isdescribed. Vhdl2Spice generates a SPICE netlist by tracing down theVHDL IIR parse tree available from the already existing VHDLanalyzer. Corresponding to each VHDL design unit, the output of theconverter is represented as a subcircuit in SPICE. By doing so, thehierarchical characteristic of VHDL is retained in the SPICErepresentation; hence future extension to both programs can be madein parallel. The Vhdl2Spice converter is also a demonstration of theextensibility of the AIRE [2] for a complete integration of VHDL-AMSwith other CAD tools.
