kqcircuits.masks.mask_layout¶
- class kqcircuits.masks.mask_layout.MaskLayout(layout, name, version, with_grid, chips_map, face_id, **kwargs)[source]¶
Bases:
object
Class representing the mask for a certain face.
A MaskLayout is used to create the cells for the mask.
- layout¶
pya.Layout for this mask
- name¶
Name of the mask
- version¶
Mask version
- with_grid¶
Boolean determining if ground grid is generated
- face_id¶
face_id of this mask layout, “1t1” | “2b1” | “2t1”
- layers_to_mask¶
dictionary of layers with mask label postfix for mask label and mask covered region creation
- covered_region_excluded_layers¶
list of layers in layers_to_mask for which mask covered region is not created
- chips_map¶
List of lists (2D-array) of strings, each string is a chip name (or — for no chip)
- align_to¶
optional exact point of placement, an (x, y) coordinate tuple. By default the mask is centered.
- chips_map_legend¶
Dictionary where keys are chip names, values are chip cells
- wafer_rad¶
Wafer radius
- wafer_center¶
Wafer center as a pya.DVector
- chips_map_offset¶
Offset to make chips_map centered on wafer
- wafer_top_flat_length¶
length of flat edge at the top of the wafer
- wafer_bottom_flat_length¶
length of flat edge at the bottom of the wafer
- dice_width¶
Dicing width for this mask layout
- text_margin¶
Text margin for this mask layout
- chip_size¶
side width of the chips (assuming square chips)
- edge_clearance¶
minimum clearance of outer chips from the edge of the mask
- chip_box_offset¶
Offset (pya.DVector) from chip origin of the chip frame boxes for this face
- chip_trans¶
DTrans applied to all chips
- mask_name_offset¶
(DEPRECATED) mask name label offset from default position (DPoint)
- mask_name_scale¶
text scaling factor for mask name label (float)
- mask_name_box_margin¶
margin around the mask name that determines the box size around the name (float)
- mask_text_scale¶
text scaling factor for graphical representation layer (float)
- mask_markers_dict¶
dictionary of all markers to be placed and kwargs to determine their position (dict)
- mask_marker_offset¶
offset of mask markers from wafer center in horizontal and vertical directions (float)
- mask_export_layers¶
list of layer names (without face_ids) to be exported as individual mask .oas files
- mask_export_density_layers¶
list of layer names (without face_ids) for which we want to calculate the coverage density
- submasks¶
list of submasks, each element is a tuple (submask mask_layout, submask position)
- extra_id¶
extra string used to create unique name for mask layouts with the same face_id
- extra_chips¶
List of tuples (name, position, trans, position_label) for chips placed outside chips_map trans is an optional transformation to use in place of self.chip_trans position_label is an optional string that overrides the automatic chip position label in the mask grid
- top_cell¶
Top cell of this mask layout
- added_chips¶
List of (chip name, chip position, chip bounding box, chip dtrans, position_label) populated by chips added during build()
- add_chips_map(chips_map, align=None, align_to=None, chip_size=None)[source]¶
Add additional chip maps to the main chip map.
The specified extra chip map, a.k.a. sub-grid, will be attached to the main grid. It may use different chip size than the main grid. For convenience left and rigtht sub-grids will be rotated 90 degrees clockwise.
- Parameters
chips_map – List of lists (2D-array) of strings, each string is a chip name (or — for no chip)
align – to what side of the main grid this sub-grid attaches. Allowed values: top, left, right and bottom.
align_to – optional exact point of placement. (x, y) coordinate tuple
chip_size – a different chip size may be used in each sub-grid
- build(chips_map_legend)[source]¶
Builds the cell hierarchy for this mask layout.
Inserts cells copied from chips_map_legend to self.top_cell at positions determined by self.chips_map. The copied cells are modified to only have layers corresponding to self.face_id, and they are translated and/or mirrored correctly based on self.face_id. Also inserts cells for mask markers, mask name label, and the circular area covered by the mask.
- Parameters
chips_map_legend – Dictionary where keys are chip names, values are chip cells
