Hi I downloaded the PCI core, and I'm trying to synthesize the CRT example. However, the synthesizer (Synplicity 7.5.1) complain that top.v try to access pci_bridge32.v 'wbm_cab_o' signal. There is no such signal defined for pci_bridge32. At most, I found a definition for wbm_cab_i, but not wbm_cab_o. Also, I had to go through a few modifications of the pci_user_constants.v file. This is because Synplify doesn't like having 2 of those files (one in CRT and one in RTL directory). During compile, the pci core used the file in RTL, and the CRT demo used the file in CRT directory. There were incompatibility. Just copying the one from CRT didn't help, and increased the error count, as it was missing a lot of defines (like the unused WB addesses mask/translations defines). Has anyone compiled the demo example, that is currently available? Thanks. _________________________________________________________________ Express yourself instantly with MSN Messenger!
