This is a black box in the sense that you do not provide VHDL code for
it, instead you put a file called bm_4b_s2.nmc... but you need it only
during the implementation stage. Before that step, this is a black
box.
> 2. And for Xilinx bus macro files i have angel_delimiter, paran_delimiter and square_delimiter so which one should be used for this tutorial ? And there are a few *.nmc files each under each delimiter, what's the different between the files ?
I dont exactly remember, but I think it is paran_delimiter : ( )
Anyway, you can simply try each of them... or have a look to the
delimiters in the .nmc file by opening it with FPGA editor or
translating it in a .xdl file. (ncd2xdl will help you more than once
in your project).
