Dear Nazca Team,
I would like to report a small bug I encountered while exporting flat gds of designs containing scaled instances (instanced created with a put statement with the scale parameter).
When exporting gds with native hierarchy, the result is correct. However, when the directive hierachy=’flat’ is added to to export_gds, the scaled instance scales the dimension of the cell’s objects, but not the position.
Here is a small code snippet to reproduce the issue:
with nd.Cell("level0", instantiate=True) as level0:
_poly = nd.Polygon(points=nd.geom.square(length=10.0, position=5), layer=1)
for i in [-1, 1]:
for j in [-1, 1]:
_poly.put(50.0 * i, 50.0 * j)
nd.Annotation(text=f"{i}_{j}", layer=3).put(50.0 * i, 50.0 * j)
with nd.Cell("level1") as level1:
level0.put(0, 0, 0, scale=5.0)
nd.export_gds(level1, filename="bug_normal.gds")
nd.export_gds(level1, filename="bug_flat.gds", hierarchy="flat")
Best,
Marco
