Gajendra You can find the pinout for the device here: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00166116.pdf
The Discovery board schematic is here: http://www.st.com/st-web-ui/static/active/en/resource/technical/layouts_and_diagrams/schematic_pack/stm32f746g-disco_sch.zip
I think you will find that the DAC pins are at processor pin PA4 and PA5. Those pins can be found in the schematic.
