Hello friends, here I m going to how to design a circuit in OrCAd. I m going to design a half adder and subtracter. Which work both one by one according to enable input. Here I m select one enable input which select the desire operation either half adder or either half subtracter . When enable input is zero the circuit work as half adder . If It has value 1 it work as half subtracter.
Firstly, click on start button and then click on OrCAD capture CIS
Then click on File and then NewProject and then click Click OK Click Click OK Give it name half adder Adder and subt Select Create a blank project Give location to save it
After doing this a blank window is open and its used to design any circuit. Click on place part
After click on place part a cascade window of place part is open as shown in fig. Type IC no. 7486 This IC is of XOR gate
Draw the XOR gate on the page and connect with wire Select wire from here
Insert the AND gate and connect with wires Type 7408 7408 IC is of AND gate
After this we have to connect digital clock Type Digclock Digital clock
Now connect the output probe and change its name Sum/Sub and carry/borrow Click on place port clickOK Select PORTLEFT-L
Change the name of the output ports to SUM/SUB and CARRY/BORROW Output port Sum/Sub Output port Carry/Borrow
Now the design of circuit is complete and now we have to check the DRC Select pspice and then New simulation Select project manager Select page1 Set run to time to 10 micro sec. Click Create Give it any name Click OK
Now everything is complete and now run the circuit Click on play button
After click on play button a blank black window is open and we have to Add traces to take output Select Add trace Click OK
