PL使用

当做zynq的FPGA单独使用，verilog语言

micro USB下载，跳线换成JTAG启动

工程里加上PYNQ的boardfile
PYNQ管脚约束

加source file

code

流水灯

## This file is a general .xdc for the PYNQ-Z2 board 
## To use it in a project:
## - uncomment the lines corresponding to used pins
## - rename the used ports (in each line, after get_ports) according to the top level signal names in the project

## Clock signal 50 MHz   20ns

set_property -dict { PACKAGE_PIN H16   IOSTANDARD LVCMOS33 } [get_ports { clk }]; #IO_L13P_T2_MRCC_35 Sch=sysclk
create_clock -add -name sys_clk_pin -period 20.00 -waveform {0 4} [get_ports { clk }];


##LEDs

set_property -dict { PACKAGE_PIN R14   IOSTANDARD LVCMOS33 } [get_ports { LED[0] }]; #IO_L6N_T0_VREF_34 Sch=led[0]
set_property -dict { PACKAGE_PIN P14   IOSTANDARD LVCMOS33 } [get_ports { LED[1] }]; #IO_L6P_T0_34 Sch=led[1]
set_property -dict { PACKAGE_PIN N16   IOSTANDARD LVCMOS33 } [get_ports { LED[2] }]; #IO_L21N_T3_DQS_AD14N_35 Sch=led[2]
set_property -dict { PACKAGE_PIN M14   IOSTANDARD LVCMOS33 } [get_ports { LED[3] }]; #IO_L23P_T3_35 Sch=led[3]

##Buttons

set_property -dict { PACKAGE_PIN D19   IOSTANDARD LVCMOS33 } [get_ports { rst }]; #IO_L4P_T0_35 Sch=btn[0]

生成bit文件，下载到板子

PS

arm当做IP核 使用uart

加block design +zynq PS,运行block automation,加载pynq的预设值
只用uart,其他去了
产生verilog实例
生成bit
导入sdk
