一、建立HPS硬件系统模型
建立HPS硬件模型有两种方式，一种是在GHRD中添加或修改， 另外一种是从0开始搭建HPS
1.1 GHRD
**GSRD(Golden System Reference Design, 黄金系统参考设计)**包含：
- GHRD(Golden Hardware Reference Design, 黄金硬件参考设计)
- 基于U-Boot的Bootloader参考
- Linux BSP参考
- Linux应用程序示例
其中GHRD包含 Cyclone V SoC / Arria V SoC Development Kit的完整HPS设计，如双核ARM Cortex-A9 MPCore HPS、用户按键输入(PIO Buttion)、用户拨码开关输入(PIO DIPSW)、LED输出(PIO LED)、64KB片上存储器、JTAG-to-Avalon主接口连接桥(JTAG Master)、JATG-UART调试模块、中断捕获器(Interrupt Capturer)及系统ID(SysID)等。使用时只需在其中添加或修改所需的内容即可。

所有设置完成后点击右下角finish，将h2f_reset引出，将三个clock连接clk
1.3 添加其他组件
添加On-chip Memory、两个JTAG to Avalon Master Bridge、System ID Peripheral、JTAG UART、LED PIO、拨码开关PIO、按键PIO、自定义中断捕获模块
自定义中断捕获模块
cpp
module intr_capturer #(
parameter NUM_INTR = 32
// active high level interrupt is expected for the input of this capturer module
)(
input clk,
input rst_n,
input [NUM_INTR-1:0] interrupt_in,
//input [31:0] wrdata,
input addr,
input read,
output [31:0] rddata
);
reg [NUM_INTR-1:0] interrupt_reg;
reg [31:0] readdata_with_waitstate;
wire [31:0] act_readdata;
wire [31:0] readdata_lower_intr;
wire [31:0] readdata_higher_intr;
wire access_lower_32;
wire access_higher_32;
always @(posedge clk or negedge rst_n) begin
if (!rst_n) interrupt_reg <= 'b0;
else interrupt_reg <= interrupt_in;
end
generate
if (NUM_INTR>32) begin : two_intr_reg_needed
assign access_higher_32 = read & (addr == 1);
assign readdata_lower_intr = interrupt_reg[31:0] & {(32){access_lower_32}};
assign readdata_higher_intr = interrupt_reg[NUM_INTR-1:32] & {(NUM_INTR-32){access_higher_32}};
end
else begin : only_1_reg
assign readdata_lower_intr = interrupt_reg & {(NUM_INTR){access_lower_32}};
assign readdata_higher_intr = {32{1'b0}};
end
endgenerate
assign access_lower_32 = read & (addr == 0);
assign act_readdata = readdata_lower_intr | readdata_higher_intr;
assign rddata = readdata_with_waitstate;
always @(posedge clk or negedge rst_n) begin
if (!rst_n) readdata_with_waitstate <= 32'b0;
else readdata_with_waitstate <= act_readdata;
end
endmodule
1.4 产生Qsys系统及通信问题
连线、设置中断、手动分配 相应外设的基地址
产生Qsys系统
Qsys将产生指定格式的硬件描述语言(HDL)文件用于Quartus工程编译，同时产生一组与硬件系统定义相关的文件，包括定义了选定的HPS外设默认引脚分配的Tcl(Tool Command Language)文件，定义了HPS与FPGA中多端口存储器控制器的Tcl文件，定义了系统所用IP和用于TimeQuest时序约束的QIP文件，可以在synthesis目录找到。
HPS 针对和FPGA 的互联通信，总共提供了 3 种形式的 AXI 总线，分别为用于 FPGA 主动向HPS 发起高效数据传输操作的 F2H AXI Slave 总线，用于 HPS 主动向 FPGA发起高效数据传输操作的 H2F AXI Master 总线，以及用于 HPS 主动向 FPGA发起一些控制或小容量数据传输操作的 H2F LW AXI Master 总线。H2F 和 F2H两个高速桥，每个桥最高支持 128-bit 位宽。
在含有HPS 的SOC系统中，由于 HPS 中的ARM Cortex-A9使用的是AXI总线协议，其提供的与FPGA通信总线也是AXI总线，AXI 总线和 Avalon MemoryMapped总线在信号类型和时序上都有一定的差别，无法直接连接。
为了支持 Platform Designer 中提供的所有使用 Avalon Memory Mapped 总线的 IP 能够方便的连接到HPS 上，Platform Designer具有 Avalon 和 AXI 总线间的自动转换功能，只需要将 Avalon Memory Mapped 总线信号连接到 AXI信号总线上即可。至于如何完成两者间的信号功能和时序的转换，Platform Designer 会自动生成相应的转换逻辑。这对于一些已经使用NIOS II CPU 开发了相应的系统和自定义 IP，可以直接在 HPS 中按照原本 IOS I中的系统架构添加 IP 连接好总线就能实现相同的功能，同时，对于用户自己开发的自定义 IP，无需做任何修改就能直接用于 SOC 系统中，大大降低了系统移植的工作量。
1.5 编译Quartus工程
在Quartus的工程中添加soc_system.qip和soc_system.v文件
点击工具栏中的File->New->Block Diagram/Schematic File，新建一个原理图文件
再右键点击原理图空白处选择Insert->Symbol，将soc_system添加入原理图文件中，右键点击soc_system->Generate Pins for Symbol Ports，为元件添加输入/输出端口
将两处hps_0_h2f_reset的输出(命名为hps_fpga_reset_n)连接到系统的复位reset信号上，然后保存
添加顶层文件

endmodule对工程文件进行分析综合
由于系统中的HPS是在Qsys集成工具中例化得到，因此除了所使用的外部存储器引脚以外，其他的专用引脚不需要再Quartus中进行分配，而是在HSP例化过程中由Qsys自动完成HPS的引脚分配，并把相关信息保存在XML格式的文件中提供给软件开发工具使用。但是HPS的外部存储器引脚需要在Quartus中进行引脚分配，该引脚分配信息同样保存在Tcl脚本文件中，只需要执行该脚本文件即可。
Tool->Tcl Scripts->hps_sdram_p0_pin_assignments.tcl->run
执行完后可以在Tcl Console总查看执行结果
最后进行外设引脚分配、工程编译产生.sof文件、下载到FPGA开发板上，整个硬件平台建立完毕
1.6 硬件系统外设的输入/输出测试
系统控制台(Syetem Console)是一种硬件调试工具，通过Tcl脚本命令可以对Qsys中定制的FPGA部分的外设进行测试。在Syetem Console中通过执行Tcl命令可以读取输入PIO寄存器的状态，也可以向输出PIO寄存器写入需要输出的结果
