Details for Predicting Analog Waveforms based on Digital Delay Estimation Schemes

Simulating digital circuits at the analog level is a challenging
and time-consuming task. To reduce simulation times, abstractions
(primarily digital ones) are used that produce reasonably
accurate results in a far less amount of time. The purpose of
this assignment is the implementation of an analog abstraction
and its experimental evaluation: Based on an existing digital
delay estimation tool, which predicts when the analog waveform of
a circuit hits a specific threshold voltage value, the analog
waveform shall be approximated and compared to accurate analog


Your task is to build a piece of software that reads the digital threshold
crossing times and properly add up suitable up and down full range switching
waveforms, resulting in pulses that accurately hit those threshold crossing
times. The generated analog waveform estimations shall then be compared
to analog SPICE simulations. Several different switching waveform
shall be used to find a good abstraction.
