Dear all,
My name is Luciano. I have an FMC176 board and I have to connect it to a VC707 board. The VC707 Ethernet reference design works fine when it is alone. My problem is that inside the Virtex 7 I have to implement a big project and Xilinx ISE fails during the implementation, if I try merging the reference design with my custom project.
Can I use the board without using the reference designs? If yes, how can I do? I read the manual 4FM_Get_Started_Guide.pdf and the FMC176_user_manual.pdf but I couldn't understand how to make it work without the reference designs.
For example, in the Ethernet reference design I saw that for the DAC0 channel 0 there are the following signals: dac0_dci (differential clock lines from FPGA to FMC176), dac0_dco (differential clock lines from FMC176 to FPGA), dac0_p0 (14 differential lines for the data to be converted) and dac0_frm_p. On the FMC176_user_manual.pdf page 21, this last differential signal is described simply as "Frame going the 1st D/A converter". I really don't know what does it mean... How am I supposed to use such signal?
In general, I need to convert both a digital signal into an analog one and vice-versa. So I would like to connect to the DAC0 my digital signal and to take the digitalized signal from the ADC0
Thank for any help.
Regards,
Luciano
