only be input, Xilinx's CLK pin is not used for clock input, can be used as normal IO.Need to be very careful!!! Two companies on the pin type of the detailed definition, although many similar, but there are a lot of different Oh!!!(3) Altera's IO feature does not have a pull-down resistor! Xilinx's IO structure also has a pull-down resistor.I developed a project encountered such a problem: the transmitter, the power is required to output low level. In the use of a company's Cyclone3, in the co

Source of the problem:The serial data interface is debugged, and the data line is expected to be nanosecond-delay in CPLD (EPM570).Resolution process:--Using Insert Lcell to delay, Lcell delay is relatively fixed but will be affected by temperature, device and other factors;The Insert method is as follows:Wire ad1_ch0_wire; = adc_b0; Lcell U0_lcell/** * ( . inch (Ad1_ch0_wire), . out (Ad1_ch0) );Note that need /* Synthesis keep */To keep Lcell is not optimized in

In Chip Planner, when you watch your feet, you'll see the pin and pad appear at the same time,such as pin120/pad174 Bank 4So what's the difference?Pin refers to the chip is packaged in the pin, that is, the user sees the pin;Pad is the pin of the wafer, is encapsulated in the inside of the chip, the user can not see.There is also a wire connection between the pad and the pin.Pad also refers to the input and output buffer/register unit.Further in the Resource property Editor see the PAD as follow

The structure of an IO in Chip planner is shownThe left side is the output section to the right of the input section, but will notice two structure: 1, register, 2,delay moduleHere's my guess: These two structures are designed for timing optimization and are mentioned in Altera's timing optimization documentation for the fast input and output registers in the Io cell.If you have the correct timing constraints, the Quartus software can automatically determine whether the register is placed in the

AbstractQuartus II is a large but extremely powerful component. Beginners are often lost in the us II category, altera provides technical training for beginners, focusing on "all Chinese 』!! IntroductionQuartus II functions are even greater than Visual Studio. Even after two years of research on FPGA and niosii, many functions of Quartus II and niosii have not been used, today, we found that Altera was ver

I just got the official Altera max10 evaluation board provided by Junlong! Please share it with us. The board is very simple, and I/O ports are all extended. Other functions are basically not available. FPGA model: 10m08sae144c8ges, 144-pin encapsulation, single-power supply, 12-bit AD function integrated, 8 K logic unit. You can take a look at max10 datasheet. Http://www.heijin.org/forum.php? MoD = viewthread tid = 31007 extra = Page % 3d1 Let'

The first step must be the pin planner, which is the view of the four generations of black gold ep4ce15f17c8. The first is to find that their pin has different color areas, which correspond to different banks respectively. Some designs require that the pin be in the same bank (first, this conjecture is followed by verification ), what does different circles and triangles mean? View --> pin legend In the figure, the pin of several brown backgrounds is used. If you place the cursor on the pin, t

When using the Altera device for design and Modelsim for post-simulation, you must first set the tool in Quartus, setting -- edatool -- Simulation-Tool Name --- Modelsim (OpenGL ); Then perform full compilation. The simulation folder is generated under the project directory. The internal Modelsim folder contains three files *. the VO file is the simulation model file after layout and wiring ,*. SDO files are standard delayed files. Add *. Vo and t
