概览

oaBitNet 在 oapy 中可用，可通过 _design 模块访问。

本页汇总 oaBitNet 当前在 oapy 中可用的 Python 接口。

详细说明

The oaBitNet class is the base class for single-bit nets that are part of the design's physical description。 You can have two or more bitNets that are equivalent。 Equivalent bitNets are traversed separately or logically as the same net。 You can create associate a connection definition, oaNetConnectDef , with a bitNet。
