Hello,

I'm trying since yesterday to interconnect the opencore mac to a
microblaze design.
After several problems solved, I'm stuck.

The "Generate netlist now works fine" but When I try to "Generate
bitstream",
I have three errors from NgdBuild :


ERROR:NgdBuild:604 - logical block 'wb2opb_0/wb2opb_0' with type 'wb2opb'
could
not be resolved. A Pin name mispelling can cause this, a missing edif or
ngc
file, or the mispelling of a type name. Symbol 'wb2opb' is not supported
in target
'spartan 3'.
ERROR:NgdBuild:604 - logical block 'opb2wb_0/opb2wb_0' with type 'opb2wb'

For the wb_ethermac core, I've created a file that includes the eth_top of
the
ethernet mac core on opencore and present the interface to the outside
world.
I've done this as a ISE project then I synthetized it to have a .ngc file
(because
I have both VHDL & Verilog there) then I created an IP from this netfile
and my vhdl top file.

Any one has a clue on what to do ? Has anyone make this work ? (I'm using
ISE/EDK 6.3)


Thanks,

Sylvain

I want to do exactly what you do. but i'm stuck to the netlist problem.

Glad to know I'm not alone ;)


I use the wb2opb from ascic.ws and now i want to use some opencore ip to
plug to my microblaze. so if you can send to this ng what you have done
to
make it work i'll apreciated

Well, finally I got a bitstream ! But ... it doesn't work as excpected so
I'm
not sure that what I've done is good.

So finally I decided to try a smaller problem, just take
Microblaze + UART + opb2wb + opencore_simple_gpio and try to make this
work.

Here's what I'm trying right now (writing this msg as I'm doing/testing it

From ground up :

* First step : Install the opb2wb
--------------------------------

- Extract the opb2wb_v1_00_a from the tar.gz and put it into your
personnal pcore dir
- Edit the bbd file and suppress the first column (C_FAMILY) to just leave
the first line
So you should have

cut here
Files
###########...#####
opb2wb_v1_00_a.edn
end cut

- Edit the mpd file and rename the 'opb_rst' into 'rst' (only the
lowercase one.
leave the OPB_rst untouched ). - Edit the netlist file (.edn) and change
the creator program to "none"
So you have (program "none") instead of (program "xilinx stuff ...")
The ngcbuild don't like to work with edif netlist created by ngc2edit
and tells
you to use the original ngc instead but we don't have it ...


*** At this point, adding a opb2wb to an existing/working design and
making all
wb connections external works (I mean you can produce a bitstream. I
don't
know if the wrapper works or not ... ****


* Second step : Creating a wb_gpio_simple EDK-compatible core
-------------------------------------------------------------

- I've used the simple_gpio core as a base to create my own very simple
gpio_core
... And I'm still at this step and won't finish tonight
I already send this which may help you.




Note that some steps might be unecessary, I just wrote that as a
collection of
all the things I made to make it generate a bitstream.

I have the same probleme. I have copied you source code and try to make
bitstream and i get the same error.

do you have corrected ?

I thing his happen because you remoce the C_FAMILY in the bbd file. but i
really not shure about this.

Hi Sylvain,

To make your custom IP accessible in XPS, you'll need to create PSF
conformed directory structure and interface files (PAO/MPD/BBD). The
Create/Import Peripheral Wizard from EDK can help you on this.

Since you already have the netlist (.ngc) and a wrapper HDL, you
shouldn't have problem to use the wizard's import flow to import your
mac core. After importing, you can use your custom IPs like any other
EDK cores bundled in the tool.

Let me know if you have any questions regarding the wizard.

Yes, I didn't notice that error because I didn't make a clean between my
tried
of yesterday and today's.

After the generate bitstream failed, copy the .edn file of the opb2wb
wrapper
into the implementation directory of your edk project and rename it to
opb2wb.edn

I didn't yet found why this is needed ... it should be done automatically
!
(or an equivalent)

Don't think so. Not removing it leads to other problems earlier. And in
EDK-wizard generated core the C_FAMILY is not there.

Yes, I have seen this thread, and also had a few private emails
from people having problems.

The real problem is that there are no clear guidelines as to
how to create truly portable netlist distributions. I have
searched the answer database, and the xilinx web site in
general, but all information I was able to find was incomplete
at best.

Could somebody from Xilinx (or anybody else who has been
successful doing this) post a step by step tutorial as to
how to create portable netlist distributions ?
