1. 什么是BSDL文件？
BSDL，Boundary Scan Description Language的缩写，即边界扫描描述语言，属于VHDL的一个子集，内容符合VHDL的语法标准，用于描述JTAG在指定设备中的实现方式，只要设备符合JTAG标准，那么它必须具有对应的BSDL文件，
BSDL文件主要包括以下信息：
  • 当前芯片所支持的最大TCK频率
  • 定义了管脚的名称和序号
  • 定义了电源、时钟、配置、IO管脚等等。每个管脚的类型，如VCC、GND、CLK，管脚的名称及序号
  • 所有可用命令寄存器
  • 所有可用的数据寄存器，包括可能的预设值，例如：器件的IDCODE
BSDL目前有两种标准IEEE 1149.1和IEEE 1149.6。IEEE 1149.6在IEEE 1149.1标准的基础上丰富了一些内容，它可以兼容IEEE 1149.1。
2. BSDL文件的获取方式1：BSDL Libraryhttps://www.bsdl.info/

这个网站几乎包括所有支持JTAG芯片的BSDL文件，超过100家半导体公司的上万款芯片，包括MCU、DSP、PowerPC、CPLD、FPGA等，现在还在持续更新中。
支持通过芯片型号或IDCODE搜索对应的BSDL文件，可以在线进行预览，非常方便
方式2：各芯片的官方网站
在各大芯片厂商的官方网站一般会提供BSDL文件，下面以Xilinx、Altera、Microsemi、ST意法半导体为例，介绍如何获取BSDL文件。
Xilinx FPGA BSDL文件获取
Xilinx CPLD/FPGA BSDL文件一般位于开发环境ISE或Vivado安装路径下：
ISE 14.7对应路径为，例如Artix-7系列XC7A100T的BSDL文件位于：
Xilinx\14.7\ISE_DS\ISE\artix7\data

Vivado 2018.3对应路径如下：
Vivado\Vivado\2018.3\ids_lite\ISE\artix7\data

除了开发环境的安装目录，Xilinx还在官方网站上提供有各系列FPGA的BSDL文件下载：
https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/device-models/bsdl-models/artix-series-fpgas.htmlAltera FPGA BSDL文件获取
由于我的电脑没装Quartus开发环境，所以不确定BSDL文件是否能在安装路径下找到，Altera官方网站也可以进行下载：
IEEE 1149.1 BSDL 文件下载
https://www.intel.cn/content/www/cn/zh/support/programmable/support-resources/board-layout/bsd-11491.html
IEEE 1149.6 BSDL 文件下载
https://www.intel.cn/content/www/cn/zh/support/programmable/support-resources/board-layout/bsd-11496.html
Microsemi FPGA BSDL文件获取
Microchip（Microsemi）FPGA的BSDL模型下载地址：
https://www.microsemi.com/product-directory/design-resources/1717-bsdl-models

ST MCU BSDL文件获取
意法半导体MCU的BSDL文件可以到官方网站搜索BSDL，就会弹出对应系列的BSDL文件包。
部分系列的BSDL文件下载地址：

4. BSDL文件的应用
BSDL文件可以在一些边界扫描的软件中被使用，如XJTAG，TopJTAG等等，通过加载对应的BSDL文件可以实现对芯片外部所有管脚的读取和控制。具体使用方法，我会在后面的文章介绍。
