Hi Paul, I believe the placement cost table is the parameter you want to change (See http://www.xilinx.com/support/answers/35534.html). You should be able to change this and other compile parameters in xps_base/XPS_ROACH[2]_base/etc/fast_runtime.opt You might find that you get on better changing

Hi Rurik and Casparians, I have a problem with the data out of the adc5g yellow block and 2's complementary change and captured by a snapshot. It seems there is bit errors during the transmission, or it could be some other problem. This is roach2 with an adc5g clocked at 1400MHz, 2-channel,

Hi Weiwei, Have you calibrated the MMCM phase using test vectors? The following repository hosts Python/corr code that may be helpful to you: https://github.com/sma-wideband/adc_tests I've recently updated the README, please see the Calibrating the data-to-clk for instructions on how to use the
