[Click] element configuration diagram drawing

[Yuliang Li, Electrical & Electronic Engineering]

Dear Sir or Madam:
My name is Yuliang Li, second year PhD student from the University of 
Bristol, UK.

Now I am doing the research for our Click. I have already had some ideas to 
extend my new elements but it seems very had to draw the elements in the 
graph. I want to ask which software do we use to draw the elements 
configuration diagram?

Thank you very much for your precious time.

All the best wishes
