I want to know what type of softwares exist and see what options I have.
You should started out by looking at PADS. A new evaluation download of the full PADS flow has just been posted on the PADS website at http://www.mentor.com/products/pcb-system-design/design-flows/pads/. This will allow you a full evaluation of PADS Logic or DxDesigner, HyperLynx Analog, SI, and Thermal, and PADS Layout.
If you just need a viewer, you can download that as well.
