hdmi ip clocking error

Question

Posted (edited)

Hi,I got this error. The old version also didn't have such a problem (I think 2016). I'll be happy if you can help me. 

note: board Arty z7 20

[DRC PDRC-34] MMCM_adv_ClkFrequency_div_no_dclk: The computed value 2475.248 MHz (CLKIN1_PERIOD, net CLK_IN_hdmi_clk) for the VCO operating frequency of the MMCME2_ADV site MMCME2_ADV_X1Y1 (cell wrapper/hdmi_i/dvi2rgb_1/U0/TMDS_ClockingX/DVI_ClkGenerator) falls outside the operating range of the MMCM VCO frequency for this device (600.000 - 1200.000 MHz). The computed value is (CLKFBOUT_MULT_F * 1000 / (CLKINx_PERIOD * DIVCLK_DIVIDE)). Please run update_timing to update the MMCM settings. If that does not work, adjust either the input period CLKINx_PERIOD (6.060000), multiplication factor CLKFBOUT_MULT_F (15.000000) or the division factor DIVCLK_DIVIDE (1), in order to achieve a VCO frequency within the rated operating range for this device.
 

## This file is a general .xdc for the ARTY Z7-20 Rev.B
## To use it in a project:
## - uncomment the lines corresponding to used pins
## - rename the used ports (in each line, after get_ports) according to the top level signal names in the project

## Clock Signal

Hi @askhunter,

Please attach a screen shot of your vivado block design.  Have you tried changing the MMCM to PLL in the DVI2RGB IP Core?

best regards,

Jon

I get the same error again. Also the clock wizard uses pll.

Hi @askhunter,

I did a little more searching and found a forum thread here where the customer is having a similar issue. A community member also posted a pass through zynq project that should be useful for your project.

best regards,

Jon
