It sounds like what you actually want is a simple BSP package for the 4DSP board you bought, with simple busses to the data channels, and a register interface for the controls. 4DSP does not really provide this. They instead provide a package based on Stellar IP. You can take the output of the stellar IP, which is a VHDL design and project for Xilinx software, and modify it to your liking. This is a fairly hard process that will require expertise with FPGA design, and is not for the faint of heart. While 4DSP claim that everything is provided to do this, I have found that there are several NGC files that prevent you from seeing the whole design. There is little to no documentation for the functionality, so you have to read there code and figure out what they are doing. You may also need to read there C code to figure out what you need to do to initialize your design. With all those caveats, it looks like the sip_FMC_204 contains the part of the code that you want to start with. Hope this helps.
From the software perspective there are two areas that the software initializes:

I want to use " [b]FMC204 Cards[/b] " (Digital to Analog Converters) in my design based Xilinx's "[b]KC705 kintex-7 kit[/b]" board.
I have seen the reference design provided by the 4 DSP for evaluating the card and I want to use my own inputs to the DAC instead of those provided by the design and want to merge my own design in that.
My problem is that I don’t want to use the Ethernet interface provided in the reference design to configure the DAC using commands and I don’t want to use the steller IP tool for my development. So please tell me that among the reference design components

[font=Symbol]·[font=Times New Roman][/size][size=7pt] [/size][/font][/font]sip_fmc_204
which component is of my use(I think it should be sip_fmc_ct_gen and sip_fmc_204 only) and how can I utilize them in my own design without having dependency on other components?
Initially I want to use an DDS output Sine and Cosine waves to feed as input to the FMC204 DAC card instead of the reference wave provided in reference design.Is there any document(other than pdfs provided with the design) which provides the complete design detail of the reference design provided so that after understanding that , I can change that according to my requirements?
