Abstract :
A software tool (TOSCA) has been developed which is intended to help non-specialists in the design of systems such as sigma-delta A/D converters and nonlinear oversampled-based signal processors. Time-domain behavioral models were developed for a set of basic building blocks upon which generic circuit structures can be constructed. Very long transients can be simulated in reasonable CPU time, thus allowing the calculation of useful system parameters. The simulator is fully user-friendly in the sense that the circuit description is made by means of a netlist (like SWITCAP) and the results of the distinct possible analysis are stored in text files compatible with standard graphic software tools. Simulation results show the flexibility and the potential of this tool
