In this talk I will present recent results from TCAD simulations using Silvaco tools.
In particular I will focus on p-bulk sensors, both standard diodes and LGADs.
At the beginning I will present a comparison of two radiation damage models for the bulk (Perugia, New Delhi).
Then I will comment on the impact of radiation damage model parameters uncertainties on macroscopic observables.
Eventually I will present some results on simulated thin LGADs under laser red light illumination.
