VIVADO下ILA使用規(guī)范指南規(guī)范.doc

1、VIVADO 下ILA 使用指南ILA是VIVADO下的一個(gè)DEBUG- IP ,類似于片上邏輯分析儀，通過(guò)在 RTL設(shè)計(jì) 中嵌入ILA核，可以抓取信號(hào)的實(shí)時(shí)波形，幫助我們定位問(wèn)題。本文檔以一個(gè)簡(jiǎn)單的 COUNTER設(shè)計(jì)為例，對(duì)VIVADO (2014.1)下ILA核的使用進(jìn)行說(shuō)明。第一部分RTL設(shè)計(jì)module counter(input clk, output 3:0 q );wire clk;/想抓取cnt信號(hào)進(jìn)行觀察(* keep = TRUE *)reg 3:0 cnt = 4d0;assign q = cnt;always(posedge clk) begincnt . . 0 )
