Goals

  • Get a taste of working with Logisim
  • Get some practice using abstractions as building blocks to build new abstractions

Objective

Construct an OR gate using transistors.

Requirements

  • your work must be in a file called or_gate.circ
  • your implementation must be in the main circuit (this would be the default)
  • your circuit must have two inputs, labeled A and B
  • your circuit must have one output labeled A_OR_B
  • you are restricted to
    • input pins
    • output pins
    • power
    • ground
    • transistors
