What is CircuitSim?

CircuitSim is an extensive SPICE circuit simulation platform that boasts a collection of more than 3,000 components alongside a modern schematic editor, all available online for free without any installation requirements. It is tailored for students, teachers, and professionals, functioning directly within a web browser, which allows it to be used seamlessly on devices like Chromebooks and school-issued laptops that may have restricted access. Users can engage in seven different analysis types, encompassing both interactive and transient analyses, with results visualized on oscilloscope-style graphs, and they have the option to place probes throughout the circuit for detailed observation. The platform also enables the creation of custom components from SPICE model text and the import of symbols from KiCad, greatly enhancing the simulation experience and versatility. CircuitSim further facilitates the importation of designs from Multisim Live prior to its planned discontinuation on September 15, 2026, making it a distinctive browser-based alternative capable of handling .csim, .ms14, and .msjs files while maintaining wiring, component arrangement, net labels, probes, and simulation settings intact. Additionally, there are classroom licensing options that introduce features like seat assignments, anonymous student seating arrangements, and dedicated private project spaces for students, which significantly enriches the learning environment. This comprehensive approach ensures that educators have the tools necessary to effectively oversee their classrooms while taking full advantage of sophisticated simulation technologies.

What is Ansys Exalto?

Ansys Exalto is a specialized software tool for post-LVS RLCk extraction that aids integrated circuit (IC) designers in accurately detecting unknown crosstalk across different design hierarchy blocks by extracting lumped-element parasitics and establishing a precise model for electrical, magnetic, and substrate interactions. This tool is designed to work seamlessly with most LVS tools and can significantly improve the RC extraction capabilities of your chosen software. By leveraging Ansys Exalto’s post-LVS RLCk extraction features, IC designers can proficiently predict electromagnetic and substrate coupling effects, allowing for the signoff of circuits that were once considered "too large to analyze." The models produced by the software can be back-annotated to the schematic or netlist, ensuring compatibility with all circuit simulators. As the demand for RF and high-speed circuits grows in modern silicon systems, accurately modeling electromagnetic coupling has become increasingly vital, as it plays a crucial role in the success of silicon designs. Therefore, Ansys Exalto proves to be an indispensable tool for designers striving to tackle the intricate challenges of contemporary circuit design with utmost accuracy and efficiency. Furthermore, its capabilities not only streamline the design process but also enhance the reliability of the final product, making it a valuable resource for any IC design team.
