oaArrayInst

模块: oapy._oa._design 导入: from oapy._oa import _design

概览

oaArrayInst 在 oapy 中可用，可通过 _design 模块访问。

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

详细说明

The oaArrayInst class implements an oaArrayInst database object that represents an array of instances of one master design。 Every cell in the array has the same orientation。 The oaArrayInst object is primarily used in the physical layout design -- for example, it can be used to represent an array of memory cells。 Note that oaArrayInsts do not provide any mechanism for specifying the connectivity between elements of the array。 They act just like oaScalarInsts in that there is a single copy of their terminals, and the width of the nets connecting to them is unaffected by the array dimensions。
