Some will hate me but i assume my words 100%. I hate Virtual stuff as they never give the truth... well maybe close to but i'd and i'll never use and trust that kind of stuff. I still prefer spending time to build a real one... yeah i have that old manner to work.

SO probably ISIS, VSM, PROTEUS( i can't remind wich is wich) from Labcenter could help.. see info on the link bellow

Some said it's a great tool... can't commernt on. I have it, but never tested and i'll probably never.

Sorry!
