Default FPGA Editor (9.2.03i) under Linux x86_64

I am not able to run the fpga_editor (64-bit ISE install) under my
Fedora 7, x86_64 system. After I set the DISPLAY variable to :0 (instead
of my :0.0 or :0.1) and trying to start it, I get following output:


/opt/xilinx_92/bin/lin64/_fpga_editor: Symbol `_XtperDisplayList' causes
overflow in R_X86_64_PC32 relocation
/opt/xilinx_92/bin/lin64/_fpga_editor: Symbol `_XtGetPerDisplayInput'
causes overflow in R_X86_64_PC32 relocation

Cannot register service: RPC: Authentication error; why = Client
credential too weak
unable to register (registryProg, registryVers, tcp)

Wind/U Error (248): Failed to connect to the registry on server

Cannot register service: RPC: Authentication error; why = Client

Overriding Xilinx file <helpmap/fpga_editor.map> with local file

Is there any chance to make it running? Does it run at least in 32-bit
ISE install? Before I used 32-bit ISE 8.2 on the same system and
fpga_editor worked fine.

By the way, why FPGA editor is still Windows application running under
Wind/U environment while the rest of Xilinx tools run native in Linux? I
do not understand.

Thanks,
Jan

A substantial amount of work is required for each appication when we
move away from Wind/U. We have decided not to do that for FPGA
Editor. Instead, we are creating a new application that is a combination
of PACE, Floorplanner, FPI, FPE and FPGA Editor. That will be
available in 11.1 (March 2009).

older version of libXt.so is needed to run WindU based programs like
FPGAEditor

see Answer Record for details

Steve,

did Xilinx consider Wine as a portablility layer for programs written in the
windows API?

I read that correctly as a year and a half from now, right? That
seems like a loooooong way off. I remember once being told that
supporting partial reconfiguration on the Spartan devices was a few
months off and that Xilinx was committed to it. I don't think that has
ever materialized. How serious is Xilinx about this new tool, PACE?
Anything more committal than just "committed"?

I have to agree, this seems a VERY long way off. The day ISE ran without
windu was a real landmark (and a good one too). Unfortunately, starting
floorplaner of fpga editor is still a real pain.

Yes. We plan to keep FPGA Editor around for a while so if there are
issues, let us know. Hopefully the issue that started this thread is
solved by the answer record provided.

I don't remember a commitement on Spartan support. We have it working
internally, but it's a very difficult flow and not something we are
prepared to support. The big difference between Spartan and Virtex is
that Spartan glitches when reconfigured. That means you need to isolate
partial regions including IO, and static routes cannot cross parial
regions. We are commited to Partial Reconfig for Virtex.

PACE is the old tool. The new tool will replace PACE, Floorplanner,
FPI, FPE and FPGA Editor. We are committed. However, in 11.1, the
new tool will not replace all FPGA Editor functions (like detailed
manual routing) so FPGA Editor will be around for things that a small
percentage of customers use until 12.1.

Now I am really confused. I read in another thread here about the
partial reconfiguration toolm PlanAhead. When I looked on the web
site it lists several Spartan 3 devices as being supported. Are you
saying that this page is incorrect?

I can't say I am intimate with the limitations of the PlanAhead tool
as I have never worked with it or even seen documentation. My
application requires the low cost of the Spartan 3 devices and uses
partial modular reconfiguration as a way to minimize the number of bit
streams. With various hardware modules connected, the combinations of
interfaces become huge. In essence, I want to create compatible
interface modules within the FPGA that can be combined at run time by
a small ARM processor. Initially the processor would query what
hardware modules are connected to the FPGA and then load the
appropriate interface modules into the FPGA.

I'm not clear on your description of "static routes", but if I can't
run signals from I/Os through one module to another, the pinouts
become very, very constraining.

The next time I am building a board that could use PlanAhead, I will
take a look, but if Spartan 3 parts are not supported, or are not very
usable with PlanAhead, then this does not really solve any of my
design problems.

I dug around and found that the Xilinx web site seems to contradict
itself in regards to support for partial reconfiguration for Spartan 3
parts. Although the "PlanAhead" web page lists several lines of
Spartan 3 parts as being supported by the PlanAhead software, I found
these comments in the "PlanAhead Software as a Platform for Partial
Reconfiguration" web page.

"Partial reconfiguration is supported in both the Virtex and Spartan(tm)
families. In this article, we will focus on implementing the partial
reconfiguration methodology as it applies to Virtex-II and Virtex-II
Pro FPGAs."

So they really do shy away from describing in any way, partial
reconfiguration for Spartan devices. I guess I will stick with my
original belief that, for all practical purposes, in contradiction to
what the Xilinx web site says, partial reconfiguration is not
supported on Spartan devices.... still.

BTW, if you would like to see where I was told, more than once, that
Xilinx was committed to supporting partial reconfiguration on the
Spartan 3 parts, I can forward the emails to you.
