MxSICO: a mixed analog digital compiler: application to oversampled A/D converters

An approach to the silicon compilation of mixed analog and digital circuits has been developed. The designs targeted by the compiler are sampled data analog circuits and bit-nibble serial digital circuits. A tool that implements this approach and the algorithms within a general framework has been developed. The tool includes a mixed analog-digital design description language and its compiler, automatic partitioning of analog and digital subcircuits, digital compilation, analog synthesis, module compilation, and physical assembly. The compiler is being used for the compilation of noise shaping oversampled (NSOS) A/D converters: these mixed signal designs include antialiasing filtering, modulation, and decimation
