qsfQuartus Setting File是Quartus工程的配置文件
包含一个Quartus工程的所有约束包括工程的软件版本信息、FPGA器件信息、引脚约分配、引脚电平分配编译约束和用于Classic TimingAnalyzer的时序约束 二、文件配置格式
2.1 set_global_assignment--配置属性格式
语法set_global_assignment
set_global_assignment [-h | -help] [-long_help] [-comment comment ] [-disable] [-entity entity_name ] -name name [-remove] [-section_id section id ] [ value ] note这里[]内的内容是可选的被扩起来的就是必须填写的参数 新建空的工程时Quartus软件根据配置自动生成的qsf文件有如下内容 set_global_assignment -name FAMILY Cyclone V set_global_assignment -name DEVICE 5CGXBC3B6U19C7 set_global_assignment -name TOP_LEVEL_ENTITY quartus_prj_demo set_global_assignment -name ORIGINAL_QUARTUS_VERSION 18.1.0 set_global_assignment -name PROJECT_CREATION_TIME_DATE 21:43:09 FEBRUARY 07, 2024 set_global_assignment -name LAST_QUARTUS_VERSION 18.1.0 Standard Edition set_global_assignment -name PROJECT_OUTPUT_DIRECTORY output_files set_global_assignment -name MIN_CORE_JUNCTION_TEMP 0 set_global_assignment -name MAX_CORE_JUNCTION_TEMP 85 set_global_assignment -name ERROR_CHECK_FREQUENCY_DIVISOR 256 set_global_assignment -name EDA_SIMULATION_TOOL ModelSim (Verilog) set_global_assignment -name EDA_TIME_SCALE 1 ps -section_id eda_simulation set_global_assignment -name EDA_OUTPUT_DATA_FORMAT VERILOG HDL -section_id eda_simulation 只需看懂意思即可由上图可以知道

The divide value must be a power of two分频值为2的幂次. Refer to the device handbook to find the frequency of the internal clock for the selected device. 其他部分有 set_global_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON set_global_assignment -name MESSAGE_DISABLE 332157 set_global_assignment -name MESSAGE_DISABLE 113015 set_global_assignment -name POWER_PRESET_COOLING_SOLUTION 23 MM HEAT SINK WITH 200 LFPM AIRFLOW set_global_assignment -name POWER_BOARD_THERMAL_MODEL NONE (CONSERVATIVE) set_global_assignment -name ENABLE_SIGNALTAP ON set_global_assignment -name PROJECT_IP_REGENERATION_POLICY NEVER_REGENERATE_IP set_global_assignment -name USE_SIGNALTAP_FILE output_files/stp1.stp set_global_assignment -name SIGNALTAP_FILE output_files/stp1.stp set_global_assignment -name QSYS_FILE ../rtl/aux_mux.qsys set_global_assignment -name IP_FILE ../rtl/ip/aux_mux_vid_clk.ip set_global_assignment -name VERILOG_FILE ../rtl/temp_sensor.v set_global_assignment -name MIF_FILE pll.mif set_global_assignment -name SDC_FILE ../rtl/user_constr.sdc set_global_assignment -name SYSTEMVERILOG_FILE ../rtl/xcvr_reconfig_arbiter.sv set_global_assignment -name TCL_SCRIPT_FILE ../tcl/Pin_Location.tcl 2.2 set_location_assignment--配置管脚格式
语法set_location_assignment
set_location_assignment [-h | -help] [-long_help] [-comment comment ] [-disable] [-fall] [-remove] [-rise] [-tag data ] -to destination [ value ]
qsf文件中的引脚分配举例 set_location_assignment PIN_AB1 -to global_resetn set_location_assignment PIN_AB2 -to hdmi_rx[0] set_location_assignment PIN_AB3 -to hdmi_rx[0](n) 注释
普通的引脚分配设置一个全局reset引脚低电平有效hdmi_rx[0]与hdmi_rx[0](n)分别是一对hdmi差分对接收端的p网络和n网络有空格或者或者括号(n)这种网络需要加双引号
2.3 set_instance_assignment
语法set_instance_assignment
set_instance_assignment [-h | -help] [-long_help] [-comment comment ] [-disable] [-entity entity_name ] [-fall] [-from source ] -name name [-remove] [-rise] [-section_id section id ] [-tag data ] [-to destination ] [ value ] qsf文件中的实例分配举例 set_instance_assignment -name IO_STANDARD LVDS -to refclk_135m_p 或者 set_instance_assignment -name IO_STANDARD LVDS -to refclk_100m_p -entity top_instance 注释
设置差分时钟P网络为LVDS电平标准Quartus中指定差分网路电平标准时只需要指明P网络的电平标准即可N网络默认同P网络的电平标准这里还给差分时钟网络refclk_100m_p指定了顶层模块名

4.1 导入qsf文件方法
Assignments 》 Import Assignments单击添加qsf文件该qsf文件可以是其他工程里面的再OK即可。 4.2 导出qsf文件方法
Assignments 》 Export Assignments无特别要求默认即可。
