evaluate IP over a restart when only a sof file is allowed

:huh:How can i evaluate pci core through a reboot (pci enumeration) while in tethered or untetherd mode? evaluation wont let me create a pof file so the device is wiped out by the rstn that accompanies restart... hmmm, how to evaluate without being allowed to reboot....???

    does a reboot really require reconfiguration when using PCI? the same is not true when using PCIe

    Normally, the RSTN signal toggles in the pc when re-started. I shared nconfig with rstn to save pins. bad move. originally, I had my own home grown pci core in, but reliability probs on various flavors of pc/bios. evaluating altera core as replacement. Think I can get around this by temp reassigning rstn to another pin ( a debug input selector) and holding it at vcc thru the re-start. pci can re-enumerate w/o triggering a re-load from flash.
