The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We have developed a simulation flow that covers steps from the signal creation in the sensitive volume to the output of the pixel digital logic that performs the time-of-arrival and time-over-threshold (ToA/ToT) measurements. This approach adds several new features to the traditional use of the TCAD - Allpix Squared duo, among which : the integration of the pixel wells from the layout in order to precisely describe the pixel key characteristics such as leakage and punch-through currents and the coupling of Monte Carlo simulations (Allpix Squared) with high precision electrical simulations (SPICE).

C2weakest assumption

That the modeled charge propagation, layout integration, and front-end response in the coupled Allpix Squared and SPICE simulations accurately represent real device behavior under irradiation and various operating conditions.

C3one line summary

A new exhaustive simulation flow combining Allpix Squared and SPICE enables detailed performance prediction for MAPS, accounting for layout effects and irradiation, and shows agreement with TJ-Monopix2 measurements.
