• Abstract: Generating Abstracts – The Abstract Generator adjusts the pin shapes created during the extract step to create the final shapes required by the place-androute tools. It then fractures these pin shapes into rectangles. – Next, the Abstract Generator applies a layer blockage model selected by the user to create the final blockage geometry in the abstract. The blockage geometry is then fractured into rectangles. – It then removes from the abstract all layers other than those with purpose pin, blockage, or boundary, and deletes the instance hierarchy. At this stage all the required geometry is at the top level of the abstract. – The Abstract Generator then annotates grid lines onto the abstract view and calculates grid pitches if these are not already present. It adjusts the placeand-route boundary to be a multiple of the grid pitches. 114 Mixed-Signal IC Design Kit
• Verify: Verify – During the verify step, terminals are compared for any differences that might exist between logical and abstract views. Pin and geometry information on manufacturing grids is checked and each abstract is tested within the target place-and-route system. 115 Mixed-Signal IC Design Kit
