Jtag To Axi4 debug 读写寄存器的tcl脚本封装

把下列代码保存为.tcl或者.txt文本保存在某个路径下

打开vivado,在tcl concle中输入 “source 文件路径”，将脚本加载至工具中后，

例如读寄存器地址32'h12345678的命令为："ReadReg 0x12345678"，此时便会返回寄存器的值，而不用每次都输入繁琐的一串命令。

写命寄存器则需要输入地址和数据，例如写寄存器地址32‘h12345678的值为0x3,"WriteReg 0x12345678   0x3"即可

proc ReadReg { Addr } {
puts "Start reading operation"
set address [format "0x%08X" $Addr]
set len 1
creat_hw_axi_txn read_txn [get_hw_axis hw_axi_1] -type read 
-address $address -len $len
run_hw_axi [get_hw_axi_txns read txn]
set read_proc [list [report_hw_axi_txn [get_hw_axi_txns read_txn]]];
set read_status_value [lindex $read_proc 0 1]
delete_hw_axi_txn [get_hw_axi_txns read txn]
return $read_status_value;
}

proc WriteReg { Addr data} {
set len 1
set address [format "0x%08X" $Addr]
set data [format "0x%08X" $data]
creat_hw_axi_txn write_txn [get_hw_axis hw_axi_1] -type write 
-address $address -len $len -data $data
run_hw_axi [get_hw_axi_txns write txn]
delete_hw_axi_txn [get_hw_axi_txns write txn]
}
