 什么是IDCODE

Xilinx FPGA Device ID Register ,用于标识芯片具体型号。

7 series devices have a 32-bit identification register called the IDCODE register. The IDCODE is based on IEEE Std 1149.1 and is a fixed, vendor-assigned value that is used to identify electrically the manufacturer and the type of device that is being addressed. This register allows easy identification of the part being tested or programmed by boundary scan, and it can be shifted out for examination by using the IDCODE instruction. The least significant bit of the IDCODE register is always 1 (based on JTAG IEEE 1149.1). The last three hex digits appear as 0x093.

Xilinx 7系列，KU, KU+都是一样的格式。

比如7系列和KU系列IDCODE表格如下，可以在UG470, UG570中找到： 其中X表示芯片自身的版本号. 这些信息还可以在 BSDL Library - Over 9000 JTAG Models 找到
