A basic circuit is selected by clicking (Left Mouse Button) on a BC in the library (DO NOT KEEP THE MOUSE BUTTON PUSHED IN, A SINGLE CLICK WILL DO!). Once selected the mouse cursor is replaced by the respective basic circuit which can now be dropped into the drawing canvas by once clicking the left mouse button again. Multiple basic circuits from the same type can be successively dropped into the drawing canvas. The actual cursor mode can be undone by clicking the right mouse button or the escape function.

Use pre-built Snippets from the BC library

The Hysopt BC library includes pre-built snippets, which are commonly-used configurations for specific base circuits (BCs). These snippets can be easily accessed by clicking the expand icon located at the bottom-right corner of a base circuit within the library. This action opens a pop-up window displaying all available snippets for the selected base circuit. Once a snippet is chosen, it will be pasted as a grouped component to your canvas.

Replacing components (Ctrl+H)

Basic circuits can be replaced by other types of basic circuits by using the replace functionality (Ctrl+H, see operations button). Multiple basic circuits can be replaced at once. E.g. in the system illustrated below, the three active mixing circuits are replaced by three passive mixing circuits with a single replace operation.
