详细说明

The oaVia class is an abstract base class for vias。 A via represents a physical connection between two adjacent route pathSegs that are on different layers。 A via references a via definition ( oaViaDef ) from the technology database that corresponds to the design where the via exists。 A via may be either a standard via or a custom via。 A standard via has a pre-defined set of via parameters that can be tailored to create a variety of vias to cover a variety of connections。 The standard via references a standard via definition。 A custom via is very much like an instance where, through its custom via definition, another design is referenced。 Custom vias often include a set of parameter values that can be used to tailor the master for each specific via。 A via can represent complex pin figures although vias are normally associated with routes。 Vias always have an oaViaHeader which contains the attributes that are constant for all vias of a given via definition。 The oaVia class can be observed by deriving from oaObserver 。 A discussion of the creation of oaVia objects can be found in the Representing Vias in OpenAccess section of the Programmers Guide。

方法说明

`obj.getHeader()`

绑定状态: 已绑定

Python 调用: obj.getHeader()

This function returns the oaViaHeader associated with this via。 The oaViaHeader is a collection of the attributes that are common to all vias of a particular via definition。 For vias of via definitions that have parameters, this function returns the via subheader。从 oaRef 重新实现。在 oaStdVia 和 oaCustomVia 中重新实现。

The pointer to the via header。

Python 示例

from oapy._oa import _design

# assume obj is a oaVia
obj.getHeader()

`obj.getViaDef()`

绑定状态: 已绑定

Python 调用: obj.getViaDef()

This function returns the oaViaDef object associated with this via。 If the oaViaDef is not bound, a NULL is returned。

from oapy._oa import _design

# assume obj is a oaVia
obj.getViaDef()

`obj.getViaDefName(name)`

绑定状态: 已绑定
