FIGURE 2-20 Using the “Show” tool.

This is easy enough to remedy. GND is a much better name for the net than N$6 anyway, so select
the “Name” tool and then click on the “N$6” net and change its name to GND.

Run the ERC again, and you should just be left with a warning like this: POWER pin IC1
VCC+ connected to N$9. This is very similar to the complaint about the GND connection but
is for the positive power supply to the IC (VCC+). Once again, anything for a quiet life, so change the
name of the net to VCC+ in the same way as you did the GND net.

Now, when you run the ERC, no window will appear; you will just see a message in the status
area at the bottom of the screen that says ERC: No errors/warnings.

Laying Out the Board

You can now start creating a board layout. The most convenient way to do this is to select the option
“Switch to Board” on the “File” menu of the Schematic Editor. This will result in a prompt saying
(and I paraphrase), “There is no board, so would you like to create one from the schematic?” This is
just what we want, so click on “Yes.”

Initially, our board does not look very promising (Figure 2-21). Clearly, we still have some work
to do.
