Hierarchical pins

When the block is selected, it will become highlighted in pink. Select Place and then Hierarchical Pin from the Capture menus ... 

Press the ESC key to stop placing pins. Next, we want to place a pin with the same name and properties in BLK2. Click the LEFT mouse button at the center of hierarchical block BLK2 to select it and then select Place and then Hierarchical Pin from the Capture menus ... 

This method shows an easy way to place identical pins in different hierarchical blocks. Use the same method to place a Vcc power pin in BLK3. Remember, click the LEFT mouse button on the block to select the block and then select Place and then Hierarchical Pin to place a pin ... 

We see that a new schematic page is created and that the page is empty except for the three ports that correspond to the pins we placed in the hierarchical block. If we zoom in around the ports, we see that they are named the same as the hierarchical pins we placed in the hierarchical block ... 

As an example of showing a hierarchical block within a hierarchical block, we will add a hierarchical block to this schematic. To place a block, select Place and then Hierarchical Block. To place a pin, select Place and then Hierarchical Pin. This block has three pins called Ollt-L, Out-R, and Ground. The reference is BLK4, and the name of the block is LOSd. The block is shown below. Use the techniques covered earlier to create this block ... 

Next, we need to specify pins for each hierarchical block. These pins will allow connections in and out of the blocks. First, click the LEFT mouse button on block BLK1 to select it ... 

The Type you select determines the shape of the pin and also specifies connectivity requirements. Capture requires that some pin types have a connection, while other types can be left fipating. Click the OK button. A pin will be placed inside the hierarchical block and move with the mouse ... 

Next, hierarchical block BLK2 will have two output pins labeled as Left and Right. Use the same method as before, except specify the Type to be Output rather than Power ... 

Notice that the output pins are shaped differently than the power pins. Next, we want to add two input pins to hierarchical block BLK3 named Left and Right. Use the same procedure as before, but specify the Type as Input ...
