2. tcl文件

tcl(tool command language)是一种功能强大的脚本语言。

下面以PL1000basex的block design导出的.tcl为例进行讲述。

新建工程

# If there is no project opened, this script will create a

# project, but make sure you do not have an existing project

# <./myproj/project_1.xpr> in the current working folder.

set list_projs [get_projects -quiet]

if { $list_projs eq "" } {

  create_project project_1 myproj -part xc7z035ffg676-2

}

上面的tcl命令的含义是，如果没有在一个工程里运行该tcl命令，则它会创建一个新的工程，并将名字设为“project_1”，器件设为“ xc7z035ffg676-2”.

设置 design name

# CHANGE DESIGN NAME HERE

variable design_name

set design_name PL1000basex

创建系统IP的实例

# Create instance: phy_addr_2, and set properties

  set phy_addr_2 [ create_bd_cell -type ip -vlnv xilinx.com:ip:xlconstant:1.1 phy_addr_2 ]

  set_property -dict [ list \

  CONFIG.CONST_VAL {2} \

  CONFIG.CONST_WIDTH {5} \

] $phy_addr_2

可以看出，在创建实例的时候进行了配置，如位宽和值。

信号连接

# Create interface connections

  connect_bd_intf_net -intf_net axi_dma_0_M_AXIS_MM2S [get_bd_intf_pins axi_dma_0/M_AXIS_MM2S] [get_bd_intf_pins upload_fifo/S_AXIS]

端口连接

# Create port connections

  connect_bd_net -net Net [get_bd_ports io_pxi_ldata] [get_bd_pins pxi_interface_0/io_pxi_ldata]

分配地址

# Create address segments

  create_bd_addr_seg -range 0x40000000 -offset 0x00000000 [get_bd_addr_spaces axi_dma_0/Data_MM2S] [get_bd_addr_segs processing_system7_0/S_AXI_HP0/HP0_DDR_LOWOCM] SEG_processing_system7_0_HP0_DDR_LOWOCM
