oaShape 在 oapy 中可用，可通过 _design 模块访问。

本页汇总 oaShape 当前在 oapy 中可用的 Python 接口。

详细说明

The oaShape class is an abstract base for classes that define specific geometry at specific locations in a design。 Together with routes, shapes specify all the manufacturable geometry in a chip layout。 Shapes can also be used for more abstract purposes。 The Text shape classes provide viewable labels on design objects。 All shapes are placed on an oaLayer and an oaPurpose 。 The design API identifies these by the layer and purpose numbers。 The corresponding names are found in the technology database。 Optionally, shapes can also belong to either an oaNet or an oaPin to provide part of the physical implementation of that object。 The oaShape class can be observed by deriving from oaObserver 。

`obj.setLPP(layerNum, purposeNum)`

绑定状态: 已绑定

Python 调用: obj.setLPP(layerNum, purposeNum)

This function moves this shape to the specified layer/purpose pair。 The new layer/purpose pair is created if it does not exist。 The old layer/purpose pair is deleted if it becomes empty。

参数

layerNum: The layer number of the specified layer-purpose pair。
purposeNum: The purpose number of the specified layer-purpose pair。 Note that oavPurposeNumberNo and oavPurposeNumberAny are only to be used in constraints and are not valid arguments here。

This function moves this shape to the specified purpose number。 The new layer/purpose pair is created if it does not exist。 The old layer/purpose pair is deleted if it becomes empty。

参数

purposeNum: The purpose number。 Note that oavPurposeNumberNo and oavPurposeNumberAny are only to be used in constraints and are not valid arguments here。

Python 调用: obj.setShieldedNet1(net)

参数

net: Bit net that is shielded by this shape。

`obj.transform(scale, angle)`

绑定状态: 已绑定

Python 调用: obj.transform(scale, angle)

This function transforms this shape by the specified scale factor and rotation angle。 The rotation angle is specified in radians。 When the angle is not a multiple of Pi/2, rectangles are converted to polygons。 PathSegs have a more specilized nature and can only be rotated by angles that are a multiple of Pi/2 to ensure that the orthogonal/diagonal nature of the pathSeg is preserved。 For ellipses and arcs, the transform is applied to their control points, and for both, their control points are based upon the bounding box。 When a non-90-degree transform is applied to a box, it is applied to each corner of the box。 The bounding box from the resulting points is then applied to the ellipse or the arc。 It is the caller's responsibility to scale and rotate instances。

Python 示例

from oapy._oa import _design

# assume obj is a oaShape
obj.transform(scale, angle)

`obj.getConnRoutes()`

绑定状态: 已绑定
