Event-driven analog-to-digital conversion, particularly level crossing A/D conversion (LC-ADC), and associated signal reconstruction techniques are still novel approaches that need further improvements to be more efficient in term of energy consumption and bandwidth resources. Among several components, this type of converter is composed of a timer block, which essentially controls the output resolution and reconstructed signal. In this paper, Authors present a level-Crossing Flash ADC (LCF-ADC) model made with Co-simulation technique where Simulink ADC model and HDL timer are associated. Besides, different interpolation algorithms are studied for signal reconstruction.
