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 simulations.


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.
