如果quartus 布局布线时提示Warning (332068): No clocks defined in design. 表示代码中未使用时钟,代码全部使用了组合逻辑。 但是有时并不是因为代码中没有使用时序逻辑,而是输出的信号与时序逻辑没有关系,输出的信号可以为wire型,但是如果这个wire型信号和时序逻辑的变量没有关系,那么quartus就认为你没有使用时序逻...
I'm using Cyclone IV DE2-115 board, I have tried connecting the CLOCK_50 input to the clocks pin according to this manual ftp://ftp.altera.com/up/pub/altera_material/13.0/boards/de2-115/de2_115_user_manual.pdf. I tried PIN_Y2 (CLOCK_50) as well as PIN_AE23 (SMA...
Everytime I compile my design in the Quartus II software (the web edition), I get a warning that states "No clocks defined in design" even though in my .bdf file I have an altpll block with the input assigned to the pin associated with with the System Clock. What am I doing wrong...
定义一个输入端口，把该端口锁定到晶振信号输入的FPGA pin脚，可直接将此端口作为全局时钟使用。很基础的一个东东，不知道是否是我理解有误
Using the -clock_vtree_type Option The -clock_vtree_type option is used in place_design to specify the type of clock tree to be used. The valid values are balanced, interSLR, and intraSLR. The default value is balanced. This option does not affect clocks using calibrated deskew. Use ...
