In the Eclypse-SW project, did you right click design_1_wrapper_hw_platform_0 -> Change Hardware Platform Specification -> then selected the downloaded design_1_wrapper.hdf from above?

Then regenerate the BSP sources:

Hello @NithinA,
I added the changes to the AXI_Zmod_DAC1411 IP on branch feature/zmod-support in vivado-library repository.
https://github.com/Digilent/vivado-library/tree/feature/zmod-support
If you want to update the hardware project with upgraded IP, you will have to:
1. git checkout the hw for the zmod_dac demo
2. cd into repo/vivado-library
3. git checkout feature/zmod-support with the latest changes
4. go to Vivado tcl console and create the hw project:
set argv ""; source digilent-vivado-scripts/digilent-vivado-checkout.tcl 5. in Reports/Report IP Status verify that /ZmodDAC_0/AXI_ZmodDAC1411_v1_0_0 has the Rev.23 (latest revision)
6. generate bitstream
7. update the sw project with new bitstream
In case you don't want to follow the above steps for creating the hardware project, here is the new bitstream file for ZmodDAC1411_Demodesign_1_wrapper.hdf.
 

Hello @Irfan,
Which board are you using ? Also could you post a screenshot of your block design ?
Cheers,
