oaCMap 在 oapy 中可用，可通过 _design 模块访问。

本页汇总 oaCMap 当前在 oapy 中可用的 Python 接口。

详细说明

The oaCMap class implements a congestion map for use by global routers。 The congestion map is a two-dimensional grid that exists for each layer in the design。 Each grid cell on each layer is called a GCell。 See the class oaGCellPattern for a discussion of how the grid size and coordinates are determined。 Each GCell can hold supply and demand counts for routes that traverse the GCell horizontally, vertically, and up/down through vias。 All of these GCell statistics are set and managed by applications。 The database does not calculate them automatically。 For all of the functions below that get statistics for a specified GCell, the function will return values of oacNullIndex for any value that is not set。 If the specified layer has not had any values set, it throws the exception oacCMapLayerNotExists。 The oaCMap class can be observed by deriving from oaObserver 。

方法说明

`obj.isSupplyDemandValid()`

绑定状态: 已绑定

Python 调用: obj.isSupplyDemandValid()

This function gets the flag indicating whether this congestion map is valid。 It is valid if any GCell statistics were set since the last change to a GCellPattern or since a call to oaCMap::deleteSupplyDemand 。
