Interesting, thanks for the info. Do you know if it is safe to operate the ADC outside does assigned constraints, assuming the model meets timing closure? Franco On 12/09/17 17:34, David MacMahon wrote: Hi, Franco, I'm not extensively familiar with the inner workings of the AGC5G yellow

Good day! I had a simular problem at the beginning of the year with a ROACH1 board. What are the symptoms of your board? What happens when you hit the power button? Kind regards Heystek On Tue, 12 Sep 2017 at 6:50 PM pei...@xao.ac.cn wrote: > Hi All, > > We have a ROACH2

Hi, Franco, I'm not extensively familiar with the inner workings of the AGC5G yellow block, but I suspect the limitation is caused by the somewhat obscure constraints imposed by the MMCM in the Virtex 6. This limitation also affects the ADC16 yellow block. More details can be found here:

[casper] adc5g Compilation Frequencies

2017-09-12 Thread Franco
Dear Casperites, Recently I've been testing adc5g block for different compilation frequency, I figured that the block can be compiled at [540, 960] U [1080, 2500] MHz, for every other frequency it gives you a "An optimum PLL solution is not available!" error. This restrictions come from the

Hi All, We have a ROACH2 board couldn't boot up, does anyone has experience about how to update the uboot file for ROACH2? We found some old memo but we are not sure which macros(mac) file is correct. Best wishes, Pei Xin Xinjiang Astronomical Observatory, CAS pei...@xao.ac.cn -- You
