Vivado Block Design - Break out individual bits of bus ?

Jump to solution

Hi,

Is there a way to break out a bus into individual bits, or into smaller buses, in the Vivado block editor ?

 

For example I have an AXI GPIO block with a 32-bit bus for the I/O. How do I connect discrete signals to individual bits of the bus ?

 

Thanks,

Pete Baston.

Hi

 

You can use  multiple Slice blocks to do this function.

It's a pity the slice block doesn't display the bits being sliced on the outside of the block. It's necessary to open up the block to see this. The same goes for the constant block...
