Hi All, I am putting together a design that uses the ADC083000. It works fine in a ROACH, but when I tried to move it to a ROACH2 it started complaining about the clock rate (error below).
Does anyone have experience using this block in a ROACH2, or have an updated version that uses the MMCM directly? Many thanks, Jonathon ERROR:MapLib:1213 - DCM to MMCM retargeting of block 'temp_baa_adc083000x2/temp_baa_adc083000x2/ADC0/DCM_ZDOK0/DCM_ADV' is not possible. Its target frequency, FVCO, is out of range. Valid FVCO range varies depending on speed grade: 600 - 1200MHz(-1), 1440MHz(-2), 1600MHz(-3). The computed FCVO is a function of the input frequency CLKIN_PERIOD, the division factor DIVCLK_DIVIDE, and the CLKFX_DIVIDE and CLKFX_MULTIPLY attributes. The CLKIN_PERIOD attribute may have been set by ngdbuild based on the user specified PERIOD constraint.
