Microprocessor Design Software

[TheBeardedQuack]

Okay so firstly I want to apologies because I've posted this just once before and someone suggested LogicSim (I think that was it's name) which granted is pretty decent for testing logic paths around but I couldn't find a way to activate multiple inputs at once (without glitching the program with the CTRL key) and if possible I want something more like what the big companies would be using where the actual chip architecture is built.

Maybe the one key thing is just me not learning the software properly but I'd still like something better.

Something looking a little like this: http://researcher.watson.ibm.com/researcher/files/us-bansal/power7_dieview.jpeg

Thanks in advance for any suggestions or constructive comments :D
