相关配置模式只要按照配置手册中的电路图连接好就可以。
xilinx的FPGA开发板的原理图，PCB，BOM都是开放的，你可以在官网上下载晌源卜相关的裂袜文件进一步研究。
官网提供的可执行文件是基于64位Linux的：zynq_linux.tar.gz.对于32位的系统，需要自己编译，解决方案如下：
1）念弯激 下载代码：git clone git://git.xilinx.com/qemu-xarm.git
2） 配置工程：
cd qemu-xarm
./configure --target-list=arm-softmmu --disable-werror --disable-kvm
3） 编译： make
4) 编译结果：
[walt@zynq7k qemu-xarm]$ ls -l arm-softmmu/qemu-system-arm
-rwxrwxr-x. 1 walt walt 18428427 Nov 6 15:27 arm-softmmu/qemu-system-arm
5） 检测环境是否OK，测试如下：
[walt@zynq7k qemu-xarm]$ ./arm-softmmu/qemu-system-arm -h
QEMU emulator version 1.0.50, Copyright (c) 2003-2008 Fabrice Bellard
usage: qemu-system-arm [options] [disk_image]
‘disk_image’ is a raw hard disk image for IDE hard disk 0
Standard options:
-h or -help display this help and exit
-version display version information and exit
-machine [type=]name[,prop[=value][,...]]
selects emulated machine (-machine ? for list)
property accel=accel1[:accel2[:...]] selects accelerator
supported accelerators are kvm, xen, tcg (default: tcg)
-cpu cpu select CPU (-cpu ? for list)
…… ……
注： 若无法执行，请按http://wiki.xilinx.com/zynq-qemu提示安装缺失仔袜的动态库。
替换官方下载的压缩包中的文件为新编译的qemu-system-arm，测试执行如闹凳下：
