i want to add a sequential D flip flop as a custom ip in a microblaze project in edk and run it using SDK , but i am not getting the required output , the main problem is to how to connect clock to the clock signal in my ip . can anyone please help

thanks in advance

You cannot do it in software. You have to do it in hardware using the Vivado suite.
Using SDK you develop the s/w that would run on the uBlaze.

A sequential D flip flop is one of the simplest elements but its connectivity complexity depends on the interface the uBlaze is having.

Nevertheless I think you must study this https://www.xilinx.com/support/docu...3_1/ug940-vivado-tutorial-embedded-design.pdf first thoroughly.
 

Well you could always add a GPIO interface to the microblaze system and connect the GPIO to the DFF and bit-bang the clock, data, and reset, and read the Q output.

If you really need a custom IP then you'll have to create a FF and wrap that with a microblaze interface, not sure what was used in ISE (guessing) but for Vivado you would make it an AXI-Lite interface to the FF. For Vivado there is a tutorial on making custom IP for the block design too, but I'm not familiar with the ISE version as I never made any custom IP for EDK.
