SpiceSharp

Structured R&D problem-solving with test-driven verification for designing and validating analog circuits using SpiceSharp and SpiceSharpParser, including .MEAS, .FOUR, .PRINT, .PLOT, .STEP, .TEMP, .MC, .NOISE, behavioral/LAPLACE sources, LTspice compatibility mode, finite source waveforms, source/passive parasitic synthesis, custom ideal diodes and nonlinear passives, and local documentation/test-suite validation. Produces human-readable reports, netlists, tests, and maintains a global backlog of active designs.
