Detailed Description

An oaDesignInst represents an instance of an oaDesign in either an oaFrame or an oaReticle. The instance specifies the actual geometry for printing on a reticle, and ultimately on a wafer. All of the geometry for a reticle is contained in oaDesignInsts that exist either directly in the oaReticle or in a hierarchy of oaFrames that are instantiated on the reticle.

The layer numbers for the wafer, which are specified on the oaImage that points to the oaReticle, do not have to use the same layer numbers as the oaDesign databases that are instantiated on the reticle. The layer numbers for the oaDesign are specified in the oaTech that it is connected to. Different oaDesigns used on a given reticle may be connected to different oaTech databases. The oaDesignInst may contain a mapping from the various wafer layer numbers it is used with to the corresponding layer number in its oaDesign. If the oaDesignInst does not have a layer mapping, all layers from its oaDesign are applied to each layer of the reticle. This option is used for features such as alignment marks that are intended to appear on all reticles.”

The size of shapes contained in an instantiated oaDesign depends on several factors. The size of a shape starts with the size as specified by the coordinates of the shape in the design database and the DBUPerUU and oaUserUnitsType for that design database. The design database need not use the same values as the oaWafer. Then the size is scaled according to the product of all the magnification factors on the oaDesignInst and its parent oaFrameInsts. The result is the size of the feature on the Wafer. In addition, shapes are scaled by the scale factor on the oaReticle to get their size as printed on the oaReticle.

The oaDesignInst class can be observed by deriving from oaObserver<oaDesignInst>.
