Best On-Premises Circuit Simulation Software of 2026

OrCAD® X is a unified PCB design software platform. It offers significant improvements to ease of use, performance and automation. Our product suite includes applications for schematic, PCB layout, simulation and data management. OrCAD X Capture, a schematic design solution for electrical circuit creation and documentation, is one of OrCAD's most popular products. PSpice®, our virtual SPICE simulation engine integrated into Capture, allows you to prototype and verify your designs using industry-leading native analog, mixed signal, and advanced analysis engines. OrCAD X Presto and OrCAD X PCB editor are two PCB layout tools that allow designers to easily collaborate between ECAD/MCAD teams and build better PCBs faster. OrCAD X Presto is our new, simplified interface for novice designers, electrical engineers and PCB designers focused on quick turn PCB designs.

Sensbench is an online simulator designed for circuits and microcontrollers, making it an excellent tool for learning, prototyping, and testing various platforms such as Arduino, ESP32, and Raspberry Pi Pico. Users can arrange virtual boards and components on a digital breadboard, connect circuits, modify sketches, compile firmware, and execute it in an emulated microcontroller while monitoring serial outputs and the behavior of components. The platform also offers capabilities for SPICE analog simulation, as well as mixed digital-analog circuits. Alongside comprehensive guided examples, it features virtual components like sensors, displays, LEDs, and relays to enhance the user experience. An innovative AI builder can transform a written project request into a detailed parts list, wiring diagram, and firmware, while an MCP server allows compatible AI clients to interact with the workbench seamlessly. The core functionalities of Sensbench are available for free through a web browser, though users can opt for additional AI credits and subscription plans for enhanced project features. Furthermore, Sensbench provides physical project kits that come with pre-flashed boards and instructional guides, including specialized kits designed for integration with Home Assistant via local Wi-Fi. This combination of virtual and physical resources makes Sensbench a versatile choice for both beginners and advanced users alike.
