Parameter Sweep with Ngspice

Strg + Left click on SimulatePARALLEL in schematic to start run!

• The number of parallel workers is adjustable
• The given index can sort the result CSV file
• Plot options available for 1 or 2 swept variables
• Switch to plot selected results as a contour plot or a normal plot based on the given index
• Switch to plot selected results as a semilogx plot, a semilogy plot, a loglog plot, or a normal plot based on the given index
• Different sweep types implemented:
  • Automatic: Auto:Begin:TotalPoints:End
  • Linear: Lin:Begin:StepSize:End
  • Decade: Dec:Begin:PointsPerDecade:End
  • Logarithmic: Log:Begin:TotalPoints:End
