You are also going to measure power consumption of the CPLD when it is implementing the propagation delay circuit at run time. 2 Propagation Delay in TTL technology Connect the four gates present in 74LS08 Quad2-input AND gate IC as shown in circuit diagram 1. Connect one input of the first AND gate(leftmost) to a square wave or clock source present on the trainer. Tie the second input to 1 i.e. VCC. Connect the output of the final AND gate(right most) to the oscilloscope. Connect clock source to channel 1 and the output from the AND gate to channel 2 of the oscilloscope so that you can visualize the propagation delay easily. Observe the propagation delay as the output of circuit 2 changes from 0 to 1. Note down the propagation delaypropagation delay as the output of circuit 2 changes from 0 to 1....
