[casper] Sync ADC16 in ROACH2
Hi everyone, When I validated my design on ROACH2, I found that there were some issues with the synchronization of the adc chip. The environment I used was ubuntu14 ise14.7 matlab2013b mlib_devel-roach2. The parameter of my XSG_core_config module is set to ROACH2:sx475t adc0_clk 200MHz. I used david's adc16 script for initialization, and there were no errors. Use adc16_status.rb to view the adc channel and find that synchronization was not successful. adc16_init.rb: Connecting to roach7... Programming roach7 with adcsync.bof...

[casper] The output data of the fft_biplex_real_2x
Hi CASPER, I've recently been designing the Corner Turner module.Converts the data shape from [input channel, frequency] to [frequency, input channel]. My understanding of FFT module is not enough, especially the relationship between data and frequency points. fft_biplex_real_2x block:Fft biplex real 2x - Casper (berkeley.edu) <https://casper.astro.berkeley.edu/w/index.php?title=Fft_biplex_real_2x=7999> This is my understanding of fft_biplex_real_2x block: The FFT of the real number input will generate complex numbers, but with a Hermitian symmetry on the Fourier components, i.e. the negative frequency part is just the complex conjugate of the corresponding positive frequency component, only half of the complex numbers are independent. To avoid wasting memory and data transportation, the input data block of two input channels are combined as the real and imaginary components respectively to form a complex input, and then FFTed together. An EQ module is placed between FFT module and Transpose module. I don't think I understand the 'frequency point' enough, so the following question may itself be wrong. My question is: 1.The fft_biplex_real_2x block sets fft size = 2^11. Its two outputs can be viewed as the output of four real streams, each containing 1024 frequency points. Is that right? 2.I designed 4 transpose modules, each responsible for a quarter frequency point of 1024. Each module corresponds to a 10gb module that packages and outputs the data. I'm curious, the fft output contains 1024 frequency points.How to divide the real stream containing 1024 frequency points? Examples: transpose_1:0-255, transpose_2:256-511, transpose_3:512-767, transpose: 768-1023. Does anyone know the F-engine design article? It is better to have fft and cornerturn module design ideas, I would like to read it! I really hope someone can communicate with me, I would appreciate it! BW!

[casper] ROACH2 output issues
Hi CASPER, I use ROACH2 to send data to the server. I wrote a script and ran it. I used wireshark to capture the data. ROACH2 sent data once, and the source address and destination address were both correct.[image: capture.png] I want ROACH to be able to send data to the server all the time, not just once. I checked the cpu status of roach and found that the CPU was only in use when the script was running.After the script is finished, the CPU status is basically 0. Can I check the CPU status to determine whether to run the bof file? I excluded the server NIC problem, the mtu is larger than the packet size. Is there any possible reason to send the packet only once? If anyone can help me, I would be grateful! BW!

Re: [casper] PAPER Correlater's Corner Turner Modes and MIRIAD Channel Mapping
Hi dan， Thank you very much for telling me this. I have a question: My current project consists of 96 dual-polarized antennas, so there are 192 signal inputs, and each F engine has 32 inputs. Therefore, I plan to use 6 ROACH2 (6 F-engines), but only 8,4,2,1 is given in CTMODE. Can I design the model of 6 F-engines by the same way?

[casper] PAPER Correlater's Corner Turner Modes and MIRIAD Channel Mapping
Hi all， I am studying the design of PAPER Correlator. PAPER Correlator Netcfg - Casper (berkeley.edu) <https://casper.astro.berkeley.edu/wiki/PAPER_Correlator_Netcfg> There are some questions about Corner Turner Mode(CTMODE) and MIRIAD Channel Mapping. 8 F engines(CTMODE):The 256 inputs by 1024 channels are presented to the X engines as exactly that. 4 F engines(CTMODE):The 128 inputs by 1024 channels are presented to the X engines as 256 inputs by 512 channels. ·· I know that each F engine has 32 inputs, so 8 for 256 and 4 for 128. But in 'X engine' I don't understand the relationship between input and channel. And，I have a silly question, why is 'Corner Turner' called that? The last part is "MIRIAD Channel Mapping". I don't understand the meaning of the abbreviation (if it is an abbreviation). Can I get this part by typing the command line? I'd appreciate it if someone could help me with that!

[casper] Novice instance of Ruby interacting with ROACH

I found it amazing that I changed the mlib_devel directory, and the
compilation succeeded.
I used mlib_devel-roach2 before, but now I use the mlib_devel given by
Lijian.
I am not sure why I solved the previous error.
I'll put it on my Github page, hoping to help people who also encounter
this error.

[casper] Re: Compilation issues related to 'rcs','PCORE' and 'gmake'
Hi CASPER，
I copied the 'name_core.ngc' file into
mlib_devel-roach2/xps_base/XPS_ROACH2_base/pcores/.
Then I commented out the code that prompts error.
At this point, the 'name_core. ngc' file is found in the specified folder
during compilation.
After a long time of compilation, this error finally appears：
ERROR: 1 constraint not met.
PAR could not meet all timing constraints. A bitstream will not be

Project Options dialog in XPS.
OR
2> Type following at the XPS prompt:

I checked the mail list and someone asked me the same question. Like the
questioner, I could not find the top_timing_summary_routed.rpt and
system_map.twr file mentioned by the respondent.
Does anyone have experience in solving this problem?
I really hope you can take the time to reply to me, I will be very grateful.

[casper] Compilation issues related to 'rcs','PCORE' and 'gmake'
e name, or the misspelling of a type name. Symbol 'transpose_core' is not supported in target 'virtex6'. Writing NGDBUILD log file "system.bld"... ERROR:Xflow - Program ngdbuild returned error code 2. Aborting flow execution... gmake: *** [__xps/system_routed] Error 1 ERROR:EDK - Error while running "gmake -f system.make bits". : XPS failed. For the error related to 'gmake', I have checked the official website(FAQ - Casper (berkeley.edu) <https://casper.astro.berkeley.edu/wiki/FAQ#Q:_Why_do_i_get_permissions_errors_when_i_run_.22make_bits.22_from_the_xps_prompt.3F>) and found a similar solution, but the problem on the website is file permission, so my error is not. Meanwhile, I confirm that I have set 'sudo lN-s make gmake'. Could someone help me answer these questions? I would be very grateful!

[casper] An error occurs when 'exportfs -a' is entered
Hi CASPER,
How's it going? I'm using ubuntu14.04.
I had some problems setting up the ROACH netboot.
- First, sudo apt-get install nfs-kernel-server nfs-common.
- Second, sudo gedit /etc/exports,and add the lines:
# Share 'roach_boot' directory/srv/roach_boot
192.168.100.0/24(rw,subtree_check,no_root_squash,insecure)
- The last, exportfs -a
- At this time, the terminal displays:
sandang@wz-sandang:/etc$ sudo exportfs -a
exportfs: No options for to NFS: suggest NFS(sync) to avoid warning
exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check'
specified for
export "NFS:to".
Assuming default behaviour ('no_subtree_check').
NOTE: this default has changed since nfs-utils version 1.0.x
May I ask what are the reasons for these?
I would be really appreciated if you reply!
Wang

[casper] Some problems with ROACH2
Hello Casperities， How's it going? I now want to copy the .fpg file to the server and connect to ROACH2's server.I have generated the.fpg file. Here's how I did it. First，plug in the power cord of ROACH2, and connect the PC with the "PPC NET" of ROACH2 with one cable. Second I type vncviewer on the terminal.Next, I enter 192.168.1.100 on the VNC screen.At this point my network is disconnected, VNC prompt me connection timeout. Is there any problem with my operation？ The last question is whether the computer should be connected to ROACH2 through katcp. How should it be connected? Is it ok to install katcp, and then it will be automatically connected? I would be really appreciated if you reply!

[casper] about core "Finedelay fstop prog" _fring stop parameter
Hi, I am using the core "Finedelay fstop prog" to construct a simple correlator. But I am some confused about the fring stop function. The document for this core is as below. Here "It means that minimum rate of incrementing fringe phase by 0.02197 degrees is after 2^17 FFT cycles." Does this means that every time when I increase the phase, it should be after some times of the FFT cycles,and the shortest time is one FFT cycle? Can I increase the phase in the one FFT cycle which means that I can increase the phase every clock? Fringe Stop : Masking parameter fft_cycle_bits determines the maximum number of FFT cycles after which the fringe phase will be incremented. For eg. Let the sync period is of 2^27 clks and number of FFT points be 2^10 then the maximum number of FFT cycles for incrementing the fringe phase by amount of resolution set for the Sine-Cos LUT = 2^27 / 2^10 = 2^17 It means that minimum rate of incrementing fringe phase by 0.02197 degrees is after 2^17 FFT cycles.

So your value tells it to increment the phase offset every 4095 cycles. I am not sure if there is some way to turn off fringe-stopping.

[casper] about complex FFT core problem
Hello,
I have tried to the complex FFT core . During the simulation,the system
generator give out the error as below:
Slice endpoints must lie between the LSB and MSB
Error occurred during Rate and Type Error Checking. Maybe the input now is
not correct,because I have connect the real_pfb's output to the complex FFT
directory.Can it work well? But I don't kown how to fix.
I have set the FFT's parameters as the fft_setting.jpg appendix.
Best Regards.

Hello all,
I've been trying to move away from such big heavy models, my ultimate goal
being to have VHDL black boxes instead of precompiled ones made from Xilinx
or Casper DSP blocks.
Jack Hickish's HDL Black Box Tutorial (
https://casper.berkeley.edu/wiki/Tutorial_HDL_Black_Box) demonstrates a
very simple example of this, but I wanted something which could be a little
bit more dynamic, e.g. in terms of bit-widths for a given input. I started
with a simple D-flip-flop block, which would automatically size itself
according to what was put in at the input. Eventually I got it right.
This is my VHDL code (important points noted with - these aren't
obvious from the above tutorial):
#
library IEEE;
use IEEE.std_logic_1164.all;
entity d_flip_flop_nbit is
generic (n_bits: positive); #
port (D : in std_logic_vector(n_bits - 1 downto 0);
clk, ce: in std_logic;
Q : out std_logic_vector(n_bits - 1 downto 0));
end d_flip_flop_nbit;

For example I have generate a sine (freq= 1/4pi)wave input the KaADC ,I found the polyphase output sine wave is still ok on the scope, but after the wide_band_real fft ( after real and image parts seperation) and power I even can't find the corresponding spectrum line. There're many messy signals on the spectrum. It seems that the fft core not works well in simulation. Does someone run into this problem? Best Regards. Oliver Wang.

[casper] about tut3 input ports
Hi, I have download the tut3.mdl. And I found than for the inports,such as [quant_gain], the sysgen always give out such error The input ports on this block must be driven by other Xilinx blocks during simulation,see the appendix. So then I have change a xilinx constant block,it seem good. But the [quant_gain] is an inport, that is an interface to the software, so which xilinx is suitable? Best Regards. Oliver Wang
Re: [casper] about error report of tut3
Yes,for I am a new man and I don't know that the blocks are actually good. I
have set the fft block and it seems simulating well.
Thank you very much.

主题: Re: [casper] about error report of tut3
Hi
The FFT blocks in the library are empty but can still be used. Put one
in a design and change the number of channels from 0 to the number you
want for your design.
They are stored empty in the library to make sure that there are no
'old' blocks stored in the library.

Hi,
I may know the reason for the problem. Because there's no
fftwideband_real in the CASPER DSP in simulink even I have installed the
mlib_vevel library. Actually in the FFTs there are nothing can be
used,see the picture appendix.
Does anyone knows how to install the fftwideband_real and other items in
Casper DSP blockset? Without that item the tut3 can't run.

But for tutorial 3, you should be able to go here: https://github.com/casper-astro/tutorials_devel/commit/ab557d6192cec4aff49634f3a20a979e81ead69f click on the view button for the file you want (e.g. tut3.mdl.gz) and then click on 'view the full file'. I think that should download it for you. We might want to think about putting the binaries in official releases for the tutorials: https://help.github.com/articles/distributing-large-binaries/ Best, Mark On Wed, Oct 15, 2014 at 1:43 PM, Wang Jinqing jqw...@shao.ac.cn wrote: Hi, I want to run the tutorial3 wideband spectrometer on my roach2. So I want to download the model file from the web https://casper.berkeley.edu/wiki/Wideband_Spectrometer on the setup line it writes like:This tutorial comes with a com plete model. But It seems nothing connection if I click in this item. So I want to build the model by myself but the document about this tutorial3 is detail enough on the https://casper.berkeley.edu/wiki/Wideband_Spectrometer nbs p; for a new man like me. So how I can download this model or build the tutorial3 model on roach2. Best Regards. Oliver Wang
[casper] about Roach2 tutorials
Hi, I have started the Roach2 board with very simple counters .It seems goes well. Now I want to use the Tutorial 3: Wideband Spectrometer and Tutorial 4: Wideband Pocket Correlator. Based these two examples I want to develop the project I want.But I found the tutorials are all for Roach1 board, how can it run smoothly on Roach2 ? Do you have tutorials that is suitable for Roach2. Best regards.

It produces a 1 every 16 msec when enabled. Looks good! I started doing timing tests but now have run into the situation where T1E fails, i.e., I cannot talk with the PIC FPGA. I don't know if this is a result of the change I made in cleaning out unneeded code, or just a random occurrence. I have power cycled the ROACH successfully but now it's in a bad mood. I guess I had better put off my timing tests and see if I can figure out what going wrong with communications. This may take a while... :(. Rich End of casper Digest, Vol 81, Issue 9 *
