Troubleshoot Layer Spacing Rules Issues

If a layer has spacing rules that are defined in the spacingTables section of a constraint group, Abstract Generator proceeds depending on the layer definition in other sections of the technology file.

If the layer is also defined in the functions subsection of the layerRules section, it represents an ideal situation and Abstract Generator proceeds without issuing any messages.
If the layer is not additionally defined in the functions subsection of the layerRules section, Abstract Generator stops further execution and issues the error message ABS-10021.

ABS-10021

Layer definition is missing from one or more of these sections in the technology file: techLayers, techLayerPurposePriorities, techDisplays; functions subsection in the layerRules section; or interconnect section of the LefDefaultRouteSpec constraint group. Use the Technology File Manager to define the layer in all the required sections in the technology file. Save and reload the file.

ABS-10059

The layer layerName, defined in the spacingTables section of the foundry constraint group, is also defined in the techDerivedLayers section of the technology file. The abstract generator does not support derived layers and this layer will, therefore, be ignored. As a result, the abstracts generated will not have any shape on this layer.
