# Placement and routing¶

PICAZZO provides some components to facilitate placement and routing of multiple PCells.

You can either just Place multiple cells (with transformations), logically connect them in a netlist, or a combination of both.

The Place-and-routing can then add waveguides to connect the components together by introducing additional waveguides.

 PlaceComponents Parametric Cell for manual Placement of multiple components. ConnectComponents Parametric Cell for logically connecting multiple components. PlaceAndConnect Parametric Cell for manual placement and Logical connection of components. PlaceAndAutoRoute Parametric Cell for manual placement and Automatic Routing.
