Description
To meet the increasingly demanding performance requirements of future High Energy Physics experiments, ongoing and future Monolithic Active Pixel Sensor (MAPS) developments focus on enhancing key characteristics (such as spatial resolution, timing precision, and energy resolution). Achieving these improvements requires advanced and accurate simulation tools.
For the electrical modeling of pixel sensor front-end circuits (such as Charge Sensitive Amplifiers (CSAs) and discriminators), simulation tools like Spectre and SPICE are commonly used. By integrating Allpix Squared with those tools, we combine detailed physics-based sensor modeling with high-precision microelectronics simulations. To facilitate this integration, we have developed a new Allpix Squared module, [NetlistWriter], which complements the existing digitizer modules [DefaultDigitizer] and [CSADigitizer].
This module generates simulation-ready netlists and creates input signals required for the electrical simulation of pixel sensor front-ends. Specifically, it dynamically modifies the front-end netlist for each simulated event by adding input current sources for every triggered pixel. The timing and amplitude of these sources are taken from the Allpix Squared event data. Additionally, the [NetlistWriter] module can launch the electrical simulation within each event.
This contribution will present the key features of the [NetlistWriter] module and demonstrate its capability by comparing simulation results with experimental data obtained from MAPS prototypes.
