Procedure

• To draw any diagram in the simulator please follow the manual given in manual section.
• In theory section we have simplified eq1: AB+A(B+C)+B(B+C) into eq2: B+AC.
• Let’s design both the Boolean Expressions in the simulator and test as below.
• Step1. We need a three input ‘OR’ gate which is not available in the simulator. So we have to first make a 3 input ‘OR’ gate with the basic gates available.

• Above circuit is a 3 input ‘OR’ design with 2 basic ‘OR’ gates.

• Let’s save it as a component with some name say ‘3IN-OR’

• Step2. Now design eq1 and eq2 as shown below.

  • Eq1 has been designed with the help of basic 2 input ‘AND’, 2 input ‘OR’ and the 3 input ‘OR’ gate developed in step 1.
  • Eq2 has been designed with the help of basic 2 input ‘AND’ and 2 input ‘OR’ gate.
