pdaSingleLayerOPS

Define single layer operations.

Single layer operations are grouped in design rule checking (DRC) and derived layer operations.

Single layer "derived"

For general comments - please refer to multi layer operations.
Some "single layer derived" layers are shown here.

Here the layerGrow, layerSize and layerShrink fill up content in this layer from another one. The A-reference should be to a GDS layer.

Design rule checking

For general comments - please refer to Multi layer DRC.
In short - be careful with the layer operations to make sure your DRC deck runs fast enough. And talk with your software partners to implement rules.

A simple exapmle is shown here.

Details

countLayer

Select polygons in the layer specified by A, where the overlap count is the same as given by the attribute count.
This operation splits the layer in polygons that are not overlapping; so all unique polygons. For each of these polygons it counts in how many "source" polygons this unique polygon is in the given layer; if it matches the count then in the output layer you will see the unique polygon.
For example if you want to see where exactly 2 polygons in A overlap, use count=2. Attributes: count.

doc

This field can be a reasonable text (many paragraphs) to document the layer operations in more detail. This is often helpful to give an idea of the layer logic, in particular when complex DRC rules are defined. Your colleques will be happy if it is easy to follow what happens.
Type pdaDocumentation documentation: Document anything relevant for the topic you want to define.

This field allows some (short, few lines) documentation to be written. It can be a long string, but the idea is not to replace a design manual.
This fields is like tex which allows documentation in LaTex format; doc is restricted to plain text.

drcAngleCheck

Validate sharp angles.

Calculate edge-edge angle values on all (healed) polygons and validate they are in the specified range. The attribuites Amax and Amin should be set, the defaults are 75.0 and 285.0 degrees.

drcConvex

This test ensures that all polygons can easily be splitted using any polygon splitter.
For convex polygons many algorithms exist that are slower or less reliable for concave polygons, so if you need to do further GDS processing, you can test this.
The algoritms that split up polygons is examples of this, but the code in OptoDesigner supports concave polygons also. Splitting up polygons is needed for large polygons as GDSII is very limited - polygon size is limited to roughly 4000 points, which is often not enough for healed (waveguide / metal) layers. So even a single large bend may already be more.
This operation performs a layer-heal first, so polygons are merged prior to the test.
