oaDiode 在 oapy 中可用，可通过 _design 模块访问。

本页汇总 oaDiode 当前在 oapy 中可用的 Python 接口。

详细说明

The oaDiode class represents an ideal clamping diode in a parasitic network for a net。 Each diode object has one value for each analysis point that the parasitic network represents。 Each value specifies the cut-in voltage, below which no current will flow through the diode。

方法说明

_design.oaDiode.create(fromNode, toNode)

绑定状态: 已绑定

Python 调用: _design.oaDiode.create(fromNode, toNode)

This function creates a diode that belongs to the parasitic network containing fromNode and toNode。 Diodes have a polarity, so the assignment of endpoints of the diode is significant: current flows through the diode from fromNode to toNode。 An exception will be thrown if fromNode and toNode do not belong to the same network。 An explicit unique ID id is required to be specified。 An exception will be thrown if the id is the reserved oacInvalidDeviceID value or if a device with the specified id value already exists。 The hasId() function will return true for devices created with this function and the getId() function will return the user-specified id。 Diodes can be created between nodes in different partitions of the same root parasitic network, where one of the partitions must be an ancestor of the other。 In this case, the diode will be created in the lower level partition, and the node in the higher level partition must have an id so that it can be found when loading the lower level partition。

参数

• fromNode: The starting node for the diode。
• toNode: The ending node for the diode。
• id: The unique ID to be assigned to the diode created。

异常

• oacInvalidDeviceIdSpecified。
• oacLocalDeviceIdExists。
• oacNodesNotInSameDesign。
• oacNodesNotInSameNetwork。
• oacNodesNotInRelatedPartitions。
• oacAncestorNodeWithoutId。
