    Subject: Re: [pci] about simulation
    Top

        Thank you very much for your kind help!
        But,taking the difference between  P-T-P and sharded bus into 
    account, would you give me some advices about how to modify the 
    testbench to be used in  a cardbus to wishbone bridge ?
        Is the configuration cycle initiated by the host or one of the MASTER
    card?
    
    regards,
    wangc
