Nexys4 RAM

Hello!

 

I'm new to Xilinx development and am trying to get up to speed. Is there a good/standard/best-practice way to initialize the nexys4's BRAM? I'm just trying to do some simple reading for now.

 

Thanks!

Re: Nexys4 RAM

b,

 

The BRAM by default is all zeroes.

 

If you wish something other than 0, you place it in your design, or use data2mem utility to add it to your bitstream.
