Can anyone provide a software model for a codec chip?  Either spice
input,  hand-coded model, or pointers to places to look for these
would be useful.  

The goal is to simultate the good codec (with digital output tied
to digital input), and also to insert faults and compare simulation 
results for faulty codecs for a master's thesis research project.

Also could any codec users please let us know what (cause and/or result)
typically goes wrong with codecs that you define as "defective".  We are 
particularly interested in faults that make the codec response marginally 
useless, rather than totally dead (no output signal).
