 When writing tests, consult these for patterns and inspiration:
 
-- **SpiceSharp**: `d:\dev\SpiceSharp\SpiceSharpTest\` — `BasicExampleTests.cs`, `Helper.cs`, `Models/`
-- **SpiceSharpParser**: `d:\dev\SpiceSharpParser\src\SpiceSharpParser.IntegrationTests\` — `BaseTests.cs`, `Components/`, `DotStatements/`, `AnalogBehavioralModeling/`, `Examples/Circuits/*.cir`
+- **SpiceSharp**: sibling workspace folder `../SpiceSharp/SpiceSharpTest/` — `BasicExampleTests.cs`, `Helper.cs`, `Models/`
+- **SpiceSharpParser**: `src/SpiceSharpParser.IntegrationTests/` — `BaseTests.cs`, `Components/`, `DotStatements/`, `AnalogBehavioralModeling/`, `Examples/Circuits/*.cir`
 - **LAPLACE**: `src/docs/articles/laplace.md`, `src/docs/articles/laplace-basics.md`, `src/SpiceSharpParser.IntegrationTests/AnalogBehavioralModeling/LaplaceTests.cs`
 
 Key patterns: tolerance-based assertions (RelTol=1e-3, AbsTol=1e-12), reference function comparison, `.MEAS` validation, string-array netlist construction.
