Mirroring components in LTspice can be done using the “Mirror” feature in the graphical interface. Here’s a step-by-step guide on how to mirror a component in LTspice:

  1. Open LTspice and create or open a schematic to mirror a component.
  2. Select the component you wish to mirror by clicking on it.
  3. Right-click on the selected component to open the context menu.
  4. In the context menu, navigate to the “Mirror” option and click on it.
  5. The selected component will be mirrored, reflecting its image along the vertical axis.
  6. Adjust the mirrored component’s position to align it properly within the circuit.
