Appendix B SIMSIDES User Guide

SIMSIDES (SIMulink‐based SIgma‐DElta Simulator) is a time‐domain behavioral simulator for Ms that has been developed as a toolbox in the MATLAB/SIMULINK environment. SIMSIDES can be used for simulating any arbitrary M architecture, implemented with both DT and CT circuit techniques. To this end, a complete list of M building blocks (integrators, resonators, quantizers, embedded DACs, and so on) is included in the toolbox. The behavioral models of these building blocks take into account the most important error mechanisms of various different circuit techniques, including SC, SI, and CT circuits. These models, validated through transistor‐level electrical simulations and by experimental measurements taken from a number of silicon prototypes, have been incorporated into the SIMULINK environment as C‐MEX S‐functions. As detailed in Chapter 5, this approach drastically increases the computational efficiency in terms of CPU time and accuracy of the simulation results.

The behavioral models included in SIMSIDES have been compiled and tested in a number of operating systems, including Mac OS X, UNIX (Solaris), Linux, and Microsoft Windows. Both 32‐bit ...
