Step 3: Display Equation Information

The Equations window allows you to view the equations, fan-in, and fan-out for a selected pin or cell. The Equations window appears automatically at the bottom of the Floorplan Editor window.

To view the equations for the reset input pin, follow these steps:

  1. If necessary, to display the Equations window, choose Equations (View menu).

  2. Select any of the input pins located on the periphery of the device in the Last Compilation floorplan. The Equations window displays the equation for the selected pin. The Fan-Out list displays the node(s) fed by the pin.
