Single-sided placement

Instructions for managing single-sided placement in Quilter, including automatic exploration, forcing double-sided layouts, and specifying single-sided constraints.

Overview

When exploring placement solutions, Quilter will automatically flip components between the top and bottom layers unless they are specifically associated with a placement region on that layer.

For every layout job, Quilter automatically tries to create single-sided layout candidates if it finds a valid placement solution that uses only one side.

How can I force double-sided placements?

If Quilter is only producing single-sided candidates and you would like to compel Quilter to utilize both sides of the board, you can:

1. Shrink your board outline, which will prompt Quilter to consider double-sided placement candidates.

2. DefinePlacement regions that associate desired components with the bottom side of the PCB.

3. Pre-place components on the bottom side of the board.

How to specify

As a preference

Quilter allows for preferential filtering by single-sided placement. To do this, go to the design parameters page and check the "Show single-sided layouts only" option. This will apply a filter during candidate review that you can remove if we don't generate any single-sided candidates.

As a requirement

Quilter will automatically try single-sided candidates first and only switch to double-sided placements if it can't find a valid solution. To make Quilter only explore single-sided placements, create Placement regions that include all components and link them to the top layer of your PCB.
