Scope and Plotting

Scope basics

Scope is the sheet-owned waveform view for simulation results and probes.

  • After a run, use Probe on a pin tip or wire for voltage, or on a component body for current.
  • Focus Scope to open its ribbon after Simulate, then choose Add signal. Search starts focused, supports signal-type filters, and stays open while you add several traces.
  • Custom Part ports appear with instance-qualified names such as X1.IN; the canonical V(net) expression is shown underneath.
  • Collapsed Scope views show a Restore Scope button in the document shell.
  • Right-click a legend chip to hide, solo, remove, or attach cursors to that trace.
  • AC plots show gain in dB and phase in degrees; cursor readouts keep those units plain.

Cursor measurements

  • Place Cursor A first, then Cursor B. Measurement buttons name the trace they target; the same actions are available from that trace's menu.
  • The in-plot readout shows x, y, delta, inverse delta, and slope for the active trace.
  • Saved measurements aggregate over the full run, visible screen, or cursor window and stay organized in the resizable rail beside the chart.
