I have been using the ROACH2 for a few years now, and using matlab r2012b and
ISE14.6. It has always worked for me.
After moving the build system to another computer, it is now broken. I can
still compile FPGAs to make a bit file. But when simulating
with Xilinx math blocks I get:

We have been using a ROACH for several years, and I have found the CASPER
mailing lists to be useful, and the community helpful. Not sure what being a
"member" of Casper is. We do not pay any fee. We just joined the mailing list.
There are ROACH conferences once a year. I have not gone, but wi
You also have to enable larger packet sizes on the enet card receiving the

The roach1 yellow block will not work on roach2 because it uses the older
style PLLs not found on the V6 chip of R2. I made a new yellow block for mkid
4x and it works fine. It is here:

1) I assume you are using the 2 tap MKID dac yellow block.
2) You need two generators. The idea is that the FPGA runs at 1/2 the DAC
sample rate. So you must
generate two samples at a time. For now, hook up I0, I1 to same output of dig.

Hi Timothy
You may have run into the ROACH2 compiler problem we found. Make sure that the
"Share coeff BRAMs where useful" option is not chosen in the "Implementati

sure of all the details. it would be interesting if someone were to try this.

I am seeing some wierd FFT problems as well. I found that if I had the FFT/PFB

It may be that your FFT is working fine. Are you using a window before the
FFT? The window can put zeros at odd bins if the input signal is just right.
You may try taking away the pfb block, and inputting random noise into the FFT
without any windowing.
