I've compiled the PCI bridge into a Spartan part on my PCI EVM. I am
able to read/write config space and I am able to read/write the config
space image in BA0. However, as soon as I try to access BA1 which is
suppose to go to WB master and a simple block ram my machine freezes.

Any ideas why an access to WB master would kill my machine?

Thanks.

Hi! Is there a possibility that you are not generating slave response in a right manner? If the WB master does not get ack or err asserted, then the transactions never finish and the PCI Bridge won't be able to transfer more data, thus the PCI bus will be in a deadlock. If this is not the case, please provide a little more data about what you are doing - what kind of transfer (read/write) causes a crash, is it a burst or single transfer etc.. And send me (on private mail - not the mailing list) the pci_user_constants.v file from the rtl directory.
