Step 5: Draw Node Lines

To draw the appropriate node lines, follow these steps:

  1. Click the Orthogonal Node Tool button on the toolbar.

  2. Draw a node line from the D input of the DFF symbol to the border of the state_m block.

  3. Repeat steps 1 through 2 to make the additional node connections shown in the following table:

    4. Draw Node From: To:
    D input of the DFF symbol border of the state_m block (already entered)
    Q output of DFF primitive OUTPUT pin yvalid
    INPUT pin clkx2 clock input of the DFFE primitive
    enable (ENA) input of the DFFE primitive Node connecting the Q output of the DFF primitive to the OUTPUT pin yvalid

  4. To create a node that can be connected by name, draw a line from the DFF symbol's clock input into an empty space. You can learn how to complete this node's connection by name later in this tutorial module.
