hdf vs bit file

Jump to solution

Hello,

 

Can someone please shed some light on the difference between hdf and bit file ?

I can create new hw spec project by using the hdf only. Does it mean that hdf binary includes the bit information inside ?

Is it that the hw project generates from hdf new bit and new bmm file ?

hdf ---- hw project --> new bit and new bmm file

 

Thank you,

Ran

The hdf file is a container file ( like a zip) that contains the files used in SDK. If you selected the include bitstream option in Vivado when exporting. The hdf will contain the bit file.

You can right click on the hdf and unzip it, or use the command open _hw_design file name.hdf in SDK command line
Note: if in 2015.1, the command is SDK open_hw_design file name.hdf

Hi,

 

It seems the thread is duplicated at http://forums.xilinx.com/t5/Embedded-Development-Tools/Failure-in-sdk-Unable-to-read-FPGA-Bitstream/td-p/602252

Hi,

 

That's right, it is duplicated. 

I hope the other thread will have a solution.
