ContributorHow the "PARAMETER"/"localparam" in verilog mapped to hardware?
Hi, I have a very basic question regarding RTL and FPGA. In RTL, generally we use parameter or localparam to define the design configuration. My question is how this "PARAMETER' or "localparam" ...

Contributor@sstrell ,
For example, I have a header pattern to send (localparam header = 0xA5A5), I will store this as local parameter and I will assign my databus for defined interval. (data_o <= header ;). As, data_o inferred into multiple D-flip flops, my specific question is how does the header will be inferred? Whether this localparam will be stored in block RAM or by means of any other primitives ?
