previously, I worked on nexys 4 DDR FPGA which have 4 PMOD port, by using 3 pmod port I had driven 3 DAC.
but now i have to transfer that code to the zc706 fpga, but zc706 have a single pmod port with 8 user pin.
signals required for DAC are sclk , sdata , synq , reset_bar.
where sclk, synq , reset_bar is same the sdata is different for 3 dac .
I had given the same sclk , synq, reset_bar to all three DAC only sdata signal I gave individually, like the image below.
now, pmod of zc706 FPGA is able to drive single DAC, but when I connect all three in an image like above fashion, is not working, please give me the suggestion for this.
