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

详细说明

The oaViaSpec class and corresponding infrastructure are deprecated and superseded by the LEFSpecialRouteSpec and the oacValidRoutingVias constraints it contains。 The oaViaSpec class provides a mechanism for defining the valid vias that can be used when routing geometric nets。 A ViaSpec object is defined for a pair of layers, and potentially has two values associated with it: a default value (an oaViaDefArrayValue , which is a default array of pointers to oaViaDefs) and a lookup table value (an oaViaDef2DTblValue , which contains an oaViaDefArrayValue for each width-based key pair in the two-dimensional table)。 If the width-based lookup table is available, the user should lookup the list of valid vias using the width of layer1 and the width of layer2。 If this returns NULL or if no lookup table is available, the default value should be used。 Note that the valid list of oaViaDefs pointed to in an oaViaDefArray is ordered by priority since power-via and other geometric routing applications choose the first viaDef in the array that matches the layers, size and other requirements of the via needed by the application。 The oaViaSpec class can be observed by deriving from oaObserver 。
