Abutment Function Flow

To enable the abutment of Pcell dummy shapes, Event 5 of the abutFunction flow gets precedence over all the other abutment events—Events 1 to 4 and Event 6. If both the overlapping Pcell pin figures or shapes support Event 5, the sequence in which the abutFunction calls these events is illustrated in the figure below.

• If either of the overlapping Pcell instances does not support Event 5, the abutFunction starts with Event 2.
• In the event that Pcell abutment fails or the dummy shapes are not considered abuttable, the abutFunction calls the following events, though the order in which these events are called is not fixed. Event 4 is triggered to allow auto-spacing, when required. Event 6 is triggered only when the abutChainEvent environment variable is set to true.
  • Abutment Event 3
  • Abutment Event 4
  • Abutment Event 6
