About

CircuitSim is a full SPICE circuit simulator with a 3,000+ component library and a modern schematic editor. No install, free to get started. Built for students, educators, and professionals. It runs in a browser tab and needs no admin rights, so it works on Chromebooks and locked-down school laptops. Run seven kinds of analysis: interactive, interactive operating point, transient, AC sweep, DC operating point, DC sweep, and parameter sweep. Results plot on oscilloscope-style charts, with probes you can drop anywhere in the circuit. Define custom parts from SPICE model text or import KiCad symbols. CircuitSim also imports Multisim Live designs ahead of that product's retirement on September 15, 2026. It is the only browser tool that opens .csim, .ms14, and .msjs files, and it rebuilds the schematic with wiring, placement, net labels, probes, and simulation settings intact. Classroom licensing adds seat assignment, anonymous student seats, and private student work.

About

Design your photonic integrated circuit in a layout-centric flow. The designer can implement their design using either a drag-and-drop or a script-driven methodology. Both of those are in the same full custom IC design layout editor that drives the physical verification and tape-out processes. L-Edit Photonics enables the fast creation of a photonic design using a drag-and-drop methodology in an IC layout editor, without having to write a single line of code. Once the design is completed, a netlist can be extracted for photonic simulation. PIC design in a complete IC layout editor, Create a layout without writing a line of code. Supports a layout-centric design flow where a schematic is not needed. Schematic flow optional with S-Edit. A simulation netlist can be created as input into a photonic simulator. Photonic simulation is supported through integration with our partners. Photonic PDKs are available from multiple foundries.
