A browser-based analog computer simulator that recreates a patch-panel workflow for building and testing analog signal networks. Users assemble circuits by dragging virtual cables between output and input jacks on an editable design surface, with undo/redo, zoom, fit, inspect, move and delete tools. Designs can be saved, loaded, or stored as drafts; a cable editor and patch validation report help manage wiring. An integrated oscilloscope plots selected signals as time traces or X/Y plots with per-channel mapping (X, Y, Z, U) and clipping control, and traces can be exported for analysis. A trace summary and status messages indicate simulation progress and whether a design or run has been initialized.
Runtime control exposes multiple modes and accuracy settings: mode selector entries include OFF, COEFF, IC, OP, HALT, REP, REPF and MINION, while solver precision ranges from Quick to Ultra. Timing parameters such as operator duration (OP-TIME), REP/REPF cycles and base solver timestep are adjustable, with an option for virtual extended simulation when OP-TIME exceeds physical limits. Coefficient potentiometers and physical-setup presets let users preview and load predefined wiring or control configurations. Auto-run on edits is off by default; runs are started manually, and simulation output can be halted or exported.
