详细说明

oaWafer 类实现一种 wafer 数据库，它是 cell 的特定 view。 This class is the main object for storing the description of a wafer and the reticles frames, and images to associate with the wafer。 All oaWafers are implemented as a file in an oaView 。 They are all associated with a triplet of library, cell, and view names, and this set of names is used to identify them。 The oaWafer class can be observed by deriving from oaObserver 。
