使用 Xilinx ChipScope对FPGA进行调试

If the prblem with your design lies at the tp-level or is fundamentally hardware-related, using ChipScope modules is probably the best way to debug them.

Example:

如何使用 Xilinx ChipScope对FPGA进行调试，具体请看教程。

-- Xilinx Chipscope -- Instantiations
chipscope_controller : chipscope_icon
port map (control0 => chipscope_control);

chipscope_logicanalyzer : chipscope_ila_1
port map (clk => clk_lb, -- #
control => chipscope_control,
trig0 => chipscope_trig0);

-- Trigger
-- chipscope_trig0 <= (not ncore_ta) and (ncore_rw);
-- here:
-- chipscope_trig0 <= cluster_system_chipscope_trig_top;
-------------------------------------------------------

-- Xilinx Chipscope
signal chipscope_trig_top_int : std_logic_vector(0 downto 0);
-------------------------------------------------------
chipscope_trig_top_int(0) <= ((not ncore_ta) and (ncore_r_w)); -- #
chipscope_trig_top <= chipscope_trig_top_int;
逻辑分析仪Xilinx ChipScope的产生有两种方法：
Core Generator（核产生器）: 产生内核，将这些内核例化后添加到原设计文件，最后综合，实现，下载。
和Core Inserter（核插入器):不需要修改原文件，它是将生成的内核添加到综合后的网表文件中.

Core Inserter 的流程为：

1）的 RTL 综合成 Netlist；

2）调用 Core Inserter 插入逻辑分析仪；

3）布置和布局；

4）产生 bit 文件下载验证。

这是一个很好的简单教程

基本步骤是：

1. Generationg ChipScope Modules
2. Incorporating and Instantiating the ChipScope Modules
3. Connecting the ChipScope Modules
4. Synthesizing, Implementing, and Running Your Design
5. Using ChipScope Analyzer
