GDS Import¶
The GDS import tab (Figure 68) provides functionality to import a GDS file as a field.
We recommend to use KLayout for creating and editing GDS files.
Limitations¶
Maximum number of layers: 10
Maximum rasterization dimension: 5,000 x 5,000 pixels
Increasing the step size reduces the rasterization dimension.
The current version does not rasterize GDS Path elements accurately
Convert GDS Path elements to GDS Boundary elements in KLayout.
KLayout > Edit > Selection > Merge Shapes
GDS Node and GDS Text elements are not rasterized
GDS Import Tab¶
Open GDS File: Select and load a GDS file
Field Size: Figure 69 shows the field size parameters
Lock Aspect Ratio: Enforce equal dX and dY
dX (nm): X-spacing between adjacent tip indentations
dY (nm): Y-spacing between adjacent tip indentations
X (µm): X-size of the field
Derived from the imported GDS X-size.Y (µm): Y-size of the field
Derived from the imported GDS Y-size.X (px): X-dimension of the field
Derived from dx (nm) and the imported GDS X-size.Y (px): Y-dimension of the field
Derived from dY (nm) and the imported GDS Y-size.Orientation (°): Orientation of the write field relative to the piezo scanner (θ)
Field Depth: Each layer in the GDS file is assigned a target depth
{Layer Id : depth (nm), ...}: Input string format
Assign 0 depth to exclude a layer.
