In this GAP note, we present the SiPM and electronics simulation of the UMD final design implemented in the Offline software. The code was developed and vali- dated with laboratory data acquired using identical components as in the production phase. Both analogical SiPM pulses and digital traces after the front-end board were acquired and compared to simulation outputs. The first using customized electronics and the second with the same electronic kits as used in the UMD production. The main features of both counter and integrator channels relevant to the detector per- formance are discussed and the agreement between simulated and laboratory data is shown. Finally, in the appendix, we comment on the implementation and use of the AMIGA SiPM simulations in Offline.
