Hi,

I am trying to synthesize the PCI Bridge in webpack 7.1 and I am
getting the following error:

ERROR:HDLCompilers:26 - "/../Documents and
Settings/OpenCores/OpenCores/pci/rtl/verilog/pci_conf_space.v" line
1784 Macro reference `PCI_AT_EN1 is not defined
ERROR: XST failed

Any help in how to define that? Thanks in advance

Regards,
Jorge

you have to use the software provided by opencore to generate the configuration file. --Alvin On 7/13/05, jtrabal at engin.umass.edu jtrabal at engin.umass.edu> wrote:

Hi Alvin, I've found the PCI bridge's configurator tool produced an invalid pci_conf_space.v for me. I had to spend a considerable amount of time understanding what the constants did and fixing them correctly. One really annoying problem was that the PCI_AMx constants were created by Cofigurator as a 20-bit constant, when it should have been 24-bits! Where is the sourcecode for the Configurator tool?

Hi Mark, Certainly I learnt more, and everything looks great now. Honestly, you'd expect the software support tool to actually work. I can't even find the sourcecode for this tool to fix it. Some of the 'defines were not valid numbers. For example: `define PCI_AT_EN0 20'hN_ 20-bits used to enable Address Translation? What does "N_" mean?

Heh, well, at the risk of biting the hand that feeds me, I've learnt not
to expect anything more than what you can download from the website. I'm
currently using the PCI core, DMA core, OCIDE core and the 16550 core
and I've come across a few problems which I've had to resolve myself
after queries go unanswered.

Mind you, I'm not complaining - I understand people provide these as-is
and then move on to other things and don't have time to support them.

No idea. I suspect it's a typo in the tool source. Wonder what the tool was written in? Regards, -- Mark McDougall, Software Engineer Virtual Logic Pty Ltd, http://www.vl.com.au> 21-25 King St, Rockdale, 2216 Ph: +612-9599-3255 Fax: +612-9599-3266

Hi Mark, Well at least the PCI core itself looks OK. I haven't found any actual bugs in the Verilog code once I got everything working. The actual Verilog source code looks very low-level and not easily maintainable. How difficult would it be to extend the design for 64-bit PCI and 64-bit WishBone bus?

Yeah, that's looking pretty solid this end too. A few problems with the
IDE core mostly, and some struggling with understanding the DMA
pass-thru limitations mainly.

To be honest, I haven't really looked inside the PCI core, mainly due to the fact that it appears to work without any problems - and I've had my fingers very firmly crossed all this time! ;) Rather, we've spent quite a bit of time trying to turn the PCI testbench software into something that we can use for arbitrary PCI transactions in a system testbench - with some limited success. Now *that* is a task in itself - though to be fair the testbench is really geared towards doing what it was originally intended - a series of 'pre-canned' tests - and for that it is remarkably thorough. Sorry I can't help with the mods. Regards, -- Mark McDougall, Software Engineer Virtual Logic Pty Ltd, http://www.vl.com.au> 21-25 King St, Rockdale, 2216 Ph: +612-9599-3255 Fax: +612-9599-3266

The configuration tool was a contribution from one of the users of PCI core, unfortunately he never provided the source code. It is best to manually configure the PCI core, documentation about the core is quite extensive. There will be a commercial support available from Bitstream Semiconductor, along with the commercial license that will allow modifications to the core to those companies that do not wish to be limited by GPL type license. regards Damjan ----- Original Message ----- From: "TAN Joseph" Joseph.TAN at Tenix.com> To: "alvin tran" alvin.h.tran at gmail.com>; "Discussion list about free, open source PCI IP core" pci at opencores.org> Sent: Thursday, July 14, 2005 1:46 AM Subject: RE: [pci] PCI Bridge Error Hi Alvin, I've found the PCI bridge's configurator tool produced an invalid pci_conf_space.v for me.

Hi, Thanks for your reply. How can I use the configuration utility for the PCi Bridge? I am trying to open that in Windows XP, but I can't. Thank you for the help.

Hi, I am trying to implement the PCI Core in the MEMEC 2s200 Spartan II board and I am a little confused in terms of the process and what I really need from the PCI folder to implement the design. Please I need help. Thanks in advance. Regards, Jorge ----- Original Message ----- From: TAN JosephJoseph.TAN at T...> To: Date: Thu Jul 14 04:03:46 CEST 2005 Subject: [pci] PCI Bridge Error

Hi Jorge, To get started the register transfer level (RTL) code is located in \pci\rtl\verilog. The top level is "pci_bridge32.v". The PDF documentation describes the core in a lot of detail. Essentially you'll have to decide what your PCI device is going to do, appropriately configure the PCI bridge's constants, and then design your WishBone peripheral to talk to the PCI core. In \pci\sw\configurator there is a configurator utility to help you get started with setting the PCI bridge's constants. This utility is very buggy so don't trust its output. However, it can help new users understand what all those 'defines do. Consult the specification and Design Documentation for more detailed information.
