| `GRT_MACRO_EXTENSION` <a id="GRT_MACRO_EXTENSION"></a>‡ | Sets the number of GCells added to the blockages boundaries from macros. A GCell is typically defined in terms of Mx routing tracks. The default GCell size is 15 M3 pitches. <br> (Default: `0`) |
| `DRT_MIN_LAYER` <a id="DRT_MIN_LAYER"></a> | An optional override to the lowest layer used in detailed routing. For example, in sky130, you may want global routing to avoid li1, but let detailed routing use li1 if it has to. <br> (Default: `RT_MIN_LAYER`)|
