Re: [partial-reconfig] Question on bus marco DPR tutorial by Gregory Mermoud

["Ye Zijia" <yezijia@xxxxxxxxxx>]

Hi,

     thanks for your reply but i have another question. For example under the paran_delimiter there are 6 different *.nmc files. What are the difference between them ? 

The file names are :

1.bm_4b_s2.nmc

2.bm_4b_s2e.nmc

3.bm_4b_v2.nmc

4.bm_4b_v2p.nmc

5.bm_4b_v.nmc

6.bm_4b_ve.nmc

so for the DPR tutorial i should use 1. bm_4b_s2.nmc right ? Thanks for your time and advice !

Regards,

Zijia

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.

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).
