| Add Shape Polygon to Cadence Allegro Symbol. |
Steps on how to add irregular shape for place bound top in Cadence Allegro v15.2 :
1. Select Shape button, then select Polygon sub-button.
2. Be sure to set the Active Class to Package Geometry and Subclass to Place_Bound_Top.
3. Then, begin to input the coordinates of the desired shape to make.
Ex. x -10.5 25 (unit: mm)
4. At the end of the irregular shape, be sure to close the polygon inorder for the shape to be filled up.
Note:
Making irregular shapes of Place_Bound _Top in other way like adding rectangle shape and then using the Shape Void Rectangle will result to corrupted Database. It's because in Edit Change to Active Class to Package Geometry and Subclass to Place_Bound_Top from for example Active Class to Package Geometry and Subclass to Assembly_Top, the whole shape is not changed to the desired active and subclass. The void part retains it's original active and subclass thus leading to corrupt the database of that symbol (symbolname.dra).
