第二种：建立TCL 文件进行管脚分配。这种方法比较灵活，是比较常用的。 这种方法具有分配灵活，方便快捷，可重用性等多方面优点。方法如下： 选择 Projects 菜单项，并选择 Generate tcl file for project 选项，系统会为你自动生成相应文件，然后你只要向其中添加你的分配内容就可以了。 还有一种方法就是直接用 new ，新建一个 TCL 文件即可，具体不再细讲。 下面是我分配的内容一部分，可供大家参考。 set_global_assignment -name FAMILY Cyclone set_global_assignment -name DEVICE EP1C3T144C8 set_global_assignment -name ORIGINAL_QUARTUS_VERSION 8.0 set_global_assignment -name PROJECT_CREATION_TIME_DATE "19:14:58 JANUARY 06, 2009" set_global_assignment -name LAST_QUARTUS_VERSION 8.0 set_global_assignment -name USE_GENERATED_PHYSICAL_CONSTRAINTS OFF -section_id eda_palace set_global_assignment -name DEVICE_FILTER_PACKAGE "ANY QFP" set_global_assignment -name LL_ROOT_REGION ON -section_id "Root Region" set_global_assignment -name LL_MEMBER_STATE LOCKED -section_id "Root Region" set_global_assignment -name DEVICE_FILTER_PIN_COUNT 144 set_global_assignment -name DEVICE_FILTER_SPEED_GRADE 8 set_global_assignment -name FITTER_EFFORT "STANDARD FIT" set_global_assignment -name BDF_FILE topDesign.bdf set_global_assignment -name QIP_FILE nios.qip set_global_assignment -name QIP_FILE altpll0.qip set_global_assignment -name USE_CONFIGURATION_DEVICE ON set_global_assignment -name STRATIX_DEVICE_IO_STANDARD "3.3-V LVTTL" set_global_assignment -name PARTITION_NETLIST_TYPE SOURCE -section_id Top set_global_assignment -name PARTITION_COLOR 14622752 -section_id Top set_location_assignment PIN_72 -to addr[7] set_location_assignment PIN_69 -to addr[6] set_location_assignment PIN_70 -to addr[5] set_location_assignment PIN_67 -to addr[4] set_location_assignment PIN_68 -to addr[3] set_location_assignment PIN_42 -to addr[2] set_location_assignment PIN_39 -to addr[1] set_location_as...
