Eight tips for solving FPGA timing problemsAdvice one, if the timing difference is not much, within 1NS, can be modified by the synthesis, layout and routing options to fix, if the difference is much, you have to move the code.Second, take a look at the timing report, pick a path with the most tight timing, and take a closer look at what the reason is, first look at the number of logical series? What kind of circuit is wrong, the multiplier or the Ram

Multi-function Selection of pins involved in FPGA: some pins can be allocated as common I/O pins or programming pins. By default, these special pins are used as programming pins. If you want to use these pins as common I/O Ports, you must set them in the FPGA development tool, select an ordinary IO port. Otherwise, the following error occurs: Error: Can't place multiple pins assigned to pin location pin_30

First, the chip is divided into chip-level and system-level Chip level is, just a chip, such as 51 single-chip microcomputer, you can write a program, download and follow the program to run, before and after the program System level is, can run operating system, such as ARM,SOC, have RAM and ROM Cpu: Computers should understand that the central processing Unit, computer computing core and control core, all of the following chips contain CPU, chip-level MPU: microprocessor, including CPU on

1. CPLD or FPGA FPGA is suitable for completing time series logic, and CPLD is suitable for completing various algorithms and combination logic; The timing delay of CPLD is even and predictable, while the wiring structure of FPGA determines the unpredictability of the delay; FPGA is more integrated than CPLD an

Arduino uploads data to shell Iot platform and interacts with FPGA. arduinofpga This article implements the interaction between Arduino and FPGA. Of course, there is no new protocol, or it is based on serial communication. Now, learning a serial communication can basically drive most modules, moreover, it can seamlessly interact with various single-chip microcomputer data. Because of its powerful Library Fu

FPGA validation is very important in Soc design, in general, to do some replacement of RAM and FIFO and corresponding code conversion. Specifically, the following steps are divided:1 Replacing Ram,fifo and clocksRAM and FIFO controllers require RAM to be placed on the top of the design, allowing RAM to be bist. Use generate as a sample of RAM to provide readability of the code.2 properly do some peripheral interfaces3 Synthesis with synplifyFor RAM us

Experiment two LED experiment content???? On the basis of experiment one, the test signal produced by Simulink is output to the LED lights on the FPGA Development Board, which will be modified on the generated hardware model, the signal sent to the FPGA is output to 8 LEDs, and the signal is assigned the PIN.Create a model???? In the instruction window of MATLAB, enter the following instruction, Hdlsetuptoo

1. Application background 1.1 The cause of metastable occurrenceIn the FPGA system, if the TSU and th of the trigger are not satisfied in the data transmission, or the release phase of the reset signal is dissatisfied with the recovery time of the effective clock edge (recovery times), the metastable state can be produced. At this time, the trigger output Q is in an indeterminate state for a long period after the effective clock edge, during which the

The FPGA download file is loaded into the internal configuration ram, and then initializes the entire FPGA Circuit Line and sets the initial value of the LUT in the chip. A system initializes the entire FPGA, regardless of its size, therefore, no matter what the design of the same chip, the download file size is fixed, as shown in. Unlike MCU, MCU will generate d

Use these design techniques and ISE function analysis tools to control power consumption The new generation of FPGA is getting faster and faster, with higher density and more logic resources. So how can we ensure that the power consumption does not increase along with this? Many design choices can affect the power consumption of the system, from explicit device selection to small frequency-based state machine value selection. In order to better un

The previous step is the hardware description language and the next step is the FPGA.After learning the hardware description language (Verilog or VHDL), how to continue the FPGA.There is no shortcut in the world, every step has to walk. Learning FPGA is also the case, on the basis of a hardware description language, you can learn the FPGA foundation.Learning Module Division and the definition of the interfa

modeling of "functional modules. The modeling method complies with the "One module, one function" principle, and adds the description of "graphics" and "Connections" in the most direct way, it improves the "solution" of the "completion module" and the "possibility" of the design ". Of course, the benefits of "low-level modeling" are more than just here. As the modeling engineering degree increases, the advantages of "low-level modeling" will become more and more prominent. Experiment 3 Config

speechless. Is it really a problem with the software version? Students told me that the only difference between a program and a program is whether an error occurs during pin configuration. However, I have checked it many times, and the configuration is correct. But at this time, I found something strange. When you carefully observe the pin planner interface, you can see two options: voltage and current. Pull to option 1. voltage is 3.3 V by default, which is normal. The current option seems to

. I have already discussed this part in detail. I 'd like to explain it briefly here. Open the Quartus II software, and double-click the kernel to go To the FPGA builder. After entering, we will create a PIO module, and there is a difference in the creation process. Let's take a look, as shown in, at Red Circle 1, we enter 1, because we only need one button (five buttons in the black gold Development Board), and input ports only is selected for the

AbstractIn Quartus II 8.1, Quartus II handbook version 8.1 Vol.4 has made some changes to the nameing Convention of aveon signal type. IntroductionUse environment: US us II 8.1 In Quartus II handbook version 8.1 Vol.4 p.6-4, Altera announced the latest naming convention. The overall change is not significant. It is worth noting that the change of the conductor interface is only one, rather than the original one. I think this change is reasonable, in the past, I had never understood the diff
