Competing against state-of-the-art neural networks in terms of accuracy is difficult, although there are clear opportunities to outperform conventional approaches in terms of power consumption and processing speed. As neuromorphic sensors generate sparse data at the focal plane itself, they are inherently energy-efficient, data-driven, and fast. It is these properties that need to be exploited to overcome the limitations of conventional approaches. In this work, we present an extended \ac{dvs} pixel model and simulator for neuromorphic systems and benchmarks, and provide validation and characterisation against a real sensor to reduce the gap between simulated and real data. Notably, our model avoids over-sampling the rendering engine, decreasing the computational cost, and modeling the essential features provided by the readout circuit. Using a dynamic variant of the MNIST dataset as a benchmarking task, we use this simulator to explore how the latency of the sensor can be used to outperform conventional sensors in terms of sensing speed. Better exploitation of the benefits offered by neuromorphic sensors requires a thorough exploration of a more realistic sensor simulation on dynamic tasks. This paper presents a step toward that goal by providing a framework for a more holistic comparison of the simulated sensors' performance on a reading task specially developed for this purpose.
