A formal representation language for signal processing -SIBA-.

CASSY (computer aided simulation system) enables very fast concept verification of signal processing systems, their architectures and algorithms. Basically, stimuli and resulting signals are represented in terms of formal specifications, like bandwitdth, dynamic range, SNR or waveforms. The signals are not represented by their amplitude values over time or frequency, but by a formal description of their waveforms using the high level signal representation language SIBA. In contrary to the time consuming processing of e.g. sample streams using conventional simulators, CASSY's formal system verification efficiently analyses the modifications of the signal descriptions due to the component/system behaviour.
