in university we had our internal program called HLCCAD - it was very nice, and now I need to do design & debug some digital circuit and wondering what is current state of art software for that kind of things (price is out of consideration for now)?
I.e. I want to visually place components, and then simulate it.
Manually writing VHDL code & looking at simulation traceouts of specific nodes is not enough.
Update: Found Logisim - this is exactly what is needed. Are there any commercial alternatives with more horsepower?
