The foundry allows you to create your own components. The logic you place determine the behavior of the custom component and the layout determines the shape. 

The input and output components you place become pins on the component. 

Probes placed in custom components will show on their layout and can display values inside. Probes can be connected to other custom components, so that nested values can be displayed. Values probed in this way can also be connected to the program component.

For the foundry, the file manager also manages the custom components. The schematic name decides the component name and the folder structure decides the components placement in the menu.`)
