SpiceSharpParser 3.3.2

SpiceSharpParser 3.3.2 expands SPICE netlist compatibility with broad LAPLACE transfer-source support, especially for PSpice/LTspice-style analog behavioral modeling.

Highlights

• Added source-level LAPLACE support for E, G, F, and H controlled sources.
• Added function-style LAPLACE(input, transfer) support in VALUE, B ... V=, and B ... I= behavioral expressions.
• Added support for common LAPLACE spellings, including {input} = {transfer}, {input} {transfer}, and LAPLACE = {input} {transfer}.
• Added M=, TD=, and DELAY= options, including inline options for function-style LAPLACE(...) calls.
• Added rational-polynomial transfer parsing in s, with validation for proper transfer functions and finite DC gain.
• Added helper-source lowering for mixed behavioral expressions and arbitrary scalar LAPLACE inputs.
• Expanded model writer support for Laplace-enabled sources.
• Added extensive OP, AC, and transient coverage for first-order filters, second/third-order filters, Butterworth filters, band-pass, notch, resonant, cascaded, and lead-compensator examples.
• Added new LAPLACE documentation, examples, limitations, and compatibility roadmap material.

Also Included Since 3.3.0

• Added utility APIs such as CircuitBuilder, StandardValues, NetlistLinter, CircuitInspector, WaveformAnalyzer, SmokeTester, SensitivityAnalyzer, and DesignSpaceExplorer.
• Expanded unit coverage for parser evaluation, token extensions, .lib processing, model writers, and standard-value helpers.
• Updated CI/SonarQube workflow configuration and README badges.

Notes

• Source-level E/G LAPLACE inputs support voltage probes: V(node) and V(node1,node2).
• Source-level F/H LAPLACE inputs support current probes: I(source).
• Transfer expressions must be finite, proper rational polynomials in s with non-singular DC gain.
• Explicit internal-state options and pure singular transfers such as 1/s are not supported yet.

SpiceSharpParser 3.3.0

Critical fixes for AC exports (breaking changes):

• VoltageDecibelExport — fixed dB formula (was missing 20.0 * multiplier)
• VoltagePhaseExport — was returning .Magnitude instead of .Phase
• VoltageRealExport — switched from RealVoltageExport to ComplexVoltageExport, returning .Value.Real

Introducing Claude Code SKILL for analog circuit design using Claude AI and SpiceSharp/SpiceSharpParser
"Structured R&D problem-solving with test-driven verification for designing analog circuits using SpiceSharp and SpiceSharpParser that produces human-readable reports, netlist and tests and maintains a global backlog of active designs."

It's bundled together with maintained list of discoveries.md that you can maintain for your needs or leave it as it is.
