// $Log: pci_bridge32.v,v $
// Revision 1.19 2004/09/23 13:48:53 mihad
// The control inputs from PCI are now muxed with control outputs
// using output enable state for given signal.
//
// Revision 1.18 2004/08/19 15:27:34 mihad
// Changed minimum pci image size to 256 bytes because
// of some PC system problems with size of IO images.
//
// Revision 1.17 2004/01/24 11:54:18 mihad
// Update! SPOCI Implemented!
//
// Revision 1.16 2003/12/19 11:11:30 mihad
// Compact PCI Hot Swap support added.
// New testcases added.
// Specification updated.
// Test application changed to support WB B3 cycles.
//
// Revision 1.15 2003/12/10 12:02:54 mihad
// The wbs B3 to B2 translation logic had wrong reset wire connected!
//
// Revision 1.14 2003/12/09 09:33:57 simons
// Some warning cleanup.
//
// Revision 1.13 2003/10/17 09:11:52 markom
// mbist signals updated according to newest convention
//
// Revision 1.12 2003/08/21 20:49:03 tadejm
// Added signals for WB Master B3.
//
// Revision 1.11 2003/08/08 16:36:33 tadejm
// Added 'three_left_out' to pci_pciw_fifo signaling three locations before full. Added comparison between current registered cbe and next unregistered cbe to signal wb_master whether it is allowed to performe burst or not. Due to this, I needed 'three_left_out' so that writing to pci_pciw_fifo can be registered, otherwise timing problems would occure.
//
// Revision 1.10 2003/08/03 18:05:06 mihad
// Added limited WISHBONE B3 support for WISHBONE Slave Unit.
// Doesn't support full speed bursts yet.
//
// Revision 1.9 2003/01/27 16:49:31 mihad
// Changed module and file names. Updated scripts accordingly. FIFO synchronizations changed.
//
// Revision 1.8 2002/10/21 13:04:33 mihad
// Changed BIST signal names etc..
//
// Revision 1.7 2002/10/18 03:36:37 tadejm
// Changed wrong signal name mbist_sen into mbist_ctrl_i.
//
// Revision 1.6 2002/10/17 22:51:50 tadejm
// Changed BIST signals for RAMs.
//
// Revision 1.5 2002/10/11 10:09:01 mihad
// Added additional testcase and changed rst name in BIST to trst
//
// Revision 1.4 2002/10/08 17:17:05 mihad
// Added BIST signals for RAMs.
//
// Revision 1.3 2002/02/01 15:25:12 mihad
// Repaired a few bugs, updated specification, added test bench files and design document
//
// Revision 1.2 2001/10/05 08:14:28 mihad
// Updated all files with inclusion of timescale file for simulation purposes.
//
// Revision 1.1.1.1 2001/10/02 15:33:46 mihad
// New project directory structure
//
//
`include "pci_constants.v"
// synopsys translate_off
