And do remember, we DO NOT do your homework for you. There are plenty of online resources about simulation software and how to do it. If you want our help, make an effort, post your code along with your problems and errors here, and then we can make the effort to help you. Just remember, most of us have day jobs. In my case, my time is worth around $100-$200 USD per hour, so remember that when I try to help you.
