1. Introduction Proteus Virtual System Modeling (VSM) by Labcenter Electronics is a powerful software suite for electronic design automation, primarily used for schematic capture, simulation, and PCB design. A significant challenge for engineers and hobbyists is simulating modern Micro-Electromechanical Systems (MEMS) sensors like the MPU6050 (a 6-axis accelerometer and gyroscope) because Proteus does not include it in its default library.

| File Extension | Purpose | Example Name | | :--- | :--- | :--- | | | Index file for the component | MPU6050.IDX | | .LIB | Library file containing the simulation model code | MPU6050.LIB | | .HEX or .TEF | Firmware/Model code for the virtual sensor | MPU6050.HEX |
