Hi! I've been using two different programs: Electronics Workbench and Logism for my plates. I use the two to compare the results and they give me similar results so far. But this time, their results are different from each other. I don't know which of the two are correct. I tried to simulate the circuit using Logism but it doesn't give me the correct result. Sadly, EWB doesn't have a simulate button. Can anyone give me another program where I can use for my plates? Please? Thank you! 
P.S. We were instructed to use NAND gates and NOR gates so I find it hard to do it manually.
