I developed a SOPC which including a PCI compiler on the ALtera PCI development kit, the configuration of PCI compiler was: Host Bridge Mode, 32bit, 33MHz, BAR0 Auto, BAR1 auto, two fixed address translation table including a configuration space and a memory space.
my question is : how can i access the configuration space to read regs sucn as Device ID or Vendor ID ?

Under what operating system?
Under Linux you simply type lspci (and then man lspci to learn more).
Under Windows, there is a tool called pcitree (and others).
PCI device drivers under Linux are pretty simple. If that is what you are interested in, then I'll post some links.
