Making Connection with Terminals

Making Connection with Terminals:

 

The final thing we need to do to complete this block of circuitry is label the terminals. Terminal naming is extremely important as it denotes the connection to be made. We could name the terminals in any fashion we liked but sensible names make the schematic more legible and easy to understand.

Power and Ground terminals are the exception to this rule, although there is no reason not to label them; an unlabelled power terminal is assigned to the VCC net and an unnamed ground terminal will be assigned to net GND.

Essentially what we are doing by labeling a terminal is making a connection to somewhere else on the schematic (a terminal with the same name) without placing a physical wire between the two objects.

As discussed previously ISIS is flexible enough to present you with several methods for editing parts – choose your preferred method for editing the terminal from the following:

  • Double click on the terminal.
  • Right click on the terminal to select it and launch the context menu and then use the Edit Properties menu option.
  • Enter Selection Mode, left click to highlight the terminal, then right click to launch it’s context menu and use the Edit Properties menu option. Remember to exit selection mode when you are finished.

Having now launched the terminals dialogue form, type in VDD in the edit field as shown below and hit ok to exit the dialogue form

 

Note that, where appropriate you should always prefix numerical terminal values with a ‘+’ or ‘-‘. For example, a terminal labeled 12V is ambiguous and you should therefore ensure it is labeled +12V or –12V

Finish the job now by editing the other terminals and labeling them appropriately such that your completed circuit block now looks like the following:
