The Proteus Design Suite combines schematic capture, SPICE circuit simulation, and PCB layout design into a single, integrated environment. Unlike many EDA tools that separate these processes, Proteus is renowned for its ability to simulate microcontrollers alongside analog and digital electronics on the schematic. Version 8.15 SP1 (Build 34318) focuses on refining the architecture introduced in v8, providing enhanced support for modern high-speed design rules and expanding the library of microcontroller models. proteus professional 815 sp1 build 34318 link
