I want to design a logic box by using Proteus. When the conditions (for example V1>V2; resistor value will be zero and otherwise resistor value become infinite) are provided, the desired values are obtained.
But I don't know how to design and provide this conditions.
If anyone who has done it or know it, if you can help I will be really appreciate.
Thanks.

Google is a great place to start, where many of us start with such questions
Thank you for your reply. But I couldn't find the things that I want. I'm having difficulty to continue to my research. That's why I needed some guidance. With a simple help may be aid for me to proceed much easily.

Is this a theoretical question or does it have a real live application?
I don't know of any electronic components that will give you zero and infinite resistance. A comparator driving a relay would give you approximately what you are asking for but you would still have some contact resistance.
