“…V. Sadkov, A. Pilkevich, K. Fomina, and E. Korshunova [7][8][9] extensively covered the conformal map-based simulation of resistors, absorbing elements, and embedded attenuators exposed to HF and UHF signals. A. Pilkevich et al [10] confirm the results obtained with the proposed simulation methods.…”

This study continues a series of papers covering the R&D of circuit simulators embedded into manufacturing equipment for the laser trimming of film and foil resistors intended to improve the final product’s performance and reduce process costs. Our paper describes the development of the ResModel laser trimming simulation software. Various types of trims and their features are presented for a circuit with a dynamic measurement DC source, and the optimal trim configurations are identified. The software can be used to estimate and display resistive element properties during the trimming such as its electrophysical parameters and their trends.
