In the past couple of years, probably the most valuable asset in developping both the hardware and the software of our PCI boards has been the VMetro PCI bus analyzer/excerciser. The analyzer allows us to watch and trace all PCI signals/cycles in real time, while the excerciser gives us the capability to probe/drive all mem/io/config address ranges which are visible from the bus which the bus analyzer board is sitting on. This excludes everything beyond the PCI bus domain unless you are able to hook an additional signal to one of the general purpose trace inputs.
In fact, I'd never ever develop a driver for whichever OS you like without such a tool - it spoils you ;-) As it turned out, it's even more valuable in software development than hardware development.
Ciao, Dani
