Hi,
I was wondering where I can find the latest stable version of the
sources for the UHD firmware and FPGA. Also, what version of Xilinx
should I use for compiling the FPGA code? Also, is there a documentation
page that has this info that I should have been looking at?
Thanks,
Arun

Thanks. I am checking out the uhd directory using:
git://code.ettus.com/ettus/uhd.git
and it gives me host/, firmware/, fpga/, and images/ directories.
Do any of the programs in host/ (especially in examples/) have any
dependencies on the main gnuradio/ code that I checked out using:
git://gnuradio.org/gnuradio.git or can everything in the uhd/ directory
be compiled standalone?
Thanks,
Arun

Do you know how I can solve this problem?

Have you run the Xilinx setup scripts (setttings[32|64].sh found in
the Xilinx directories?
I like to setup a level of indirection, with wrapper scripts pointing
at the Xilinx executables, as they have been historically finicky:
kfleming@wisdom:~$ cat `which ise`
#!/bin/sh

There's not much documentation on the benchmark code rather than what's
included in the folder. You'll need to go through the code to understand its
operation.

This is not a xilinx problem, it is a cmake issue due to weird
interaction with the settings64.sh. settings64.sh sets the
LD_LIBRARY_PATH to the ISE/, EDK/ etc. directories of Xilinx. cmake then
looks for libstdc++.so.6, finds the one in Xilinx, and barfs because
that libstdc++ requires some version of g++ which it doesn't find. If I
remove the call to settings64.sh in my .bashrc, I don't have the problem.
So, it seems like Xilinx wants the environment one way - with its
directories at the beginning of the LD_LIBRARY_PATH, and cmake wants it
the other (sensible) way.
I ended up using something similar to your solution. The make files call
xtclsh, not ise, so your method probably won't work directly, but I just
created a xtclsh in /usr/local/bin/ that indirects to the real xtclsh in
a manner similar to yours below, and that solves the problem. Both the
FPGA and firmware now build without clobbering each other.
It would have been much nicer if Xilinx had done the sensible thing
itself, putting wrappers around its executables, rather than polluting
the entire environment with variables only it needs.

Subject: [USRP-users] timing constraints and resource utilization for
usrp2 fpga code
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi,
I downloaded and compiled the UHD fpga code for USRP2 using Xilinx 12.4.
However, its resource utilization seems way higher than the original
non-UHD fpga code that worked with Xilinx 10.3.
For comparison, the UHD device utilization is:
Device Utilization Summary:
Number of BUFGMUXs 8 out of 8 100%
Number of DCMs 3 out of 4 75%
Number of External DIFFMs 3 out of 152 1%
Number of LOCed DIFFMs 3 out of 3 100%
Number of External DIFFSs 3 out of 151 1%
Number of LOCed DIFFSs 3 out of 3 100%
Number of External IOBs 303 out of 333 90%
Number of LOCed IOBs 303 out of 303 100%
Number of MULT18X18s 27 out of 40 67%
Number of RAMB16s 25 out of 40 62%
Number of Slices 16534 out of 20480 80%
Number of SLICEMs 1924 out of 10240 18%
and the non-UHD device utilization is:
Device Utilization Summary:
Number of BUFGMUXs 6 out of 8 75%
Number of DCMs 1 out of 4 25%
Number of External DIFFMs 3 out of 152 1%
Number of LOCed DIFFMs 3 out of 3 100%
Number of External DIFFSs 3 out of 151 1%
Number of LOCed DIFFSs 3 out of 3 100%
Number of External IOBs 259 out of 333 77%
Number of LOCed IOBs 259 out of 259 100%
Number of MULT18X18s 16 out of 40 40%
Number of RAMB16s 32 out of 40 80%
Number of Slices 12027 out of 20480 58%
Number of SLICEMs 1356 out of 10240 13%
(this particular version is using 4 fewer RAMB16s, but that is the only
resource which the UHD version is using fewer of).
Also, the UHD code is failing to meet timing. Is this going to lead to
flakiness or problems when running the code? Are there options I can set
to get the code to meet timing, at the cost of greater compile time?
Thanks,
Arun
