FPGA DDR3 DebuggingSPARTAN6 FPGA chip integrates the MCB hard core, it can support to DDR3. The MiG IP core is available in Xilinx's development tools Xilinx ise, which designers can use to directly generate the DDR3 controller design module and complete the configuration via the MIG GUI graphical interface.First, establish the ISE project and add the MiG IP core,Next to the MiG IP core configuration, the m

There are two types of RAM, BLock RAM, and distributed RAM on the FPGA.Block Ram:1. Bram is a custom RAM resource in FPGA. The location is fixed, for example Bram is a column-by-column distribution, which can result in a longer route delay between user logic and Bram. For the simplest example, in a large-scale FPGA, if you run out of all the Bram, the performance will generally drop, even if the route is no

Why FPGA prototype verification?FPGA prototype verification can evaluate the chip function and performance before the IC flow sheet, and can provide the software designer with a verification platform. All designs, whether SOC or ASIC, need to be validated (functional and timing verification) to ensure that the IC implementation model matches the desired design performance. Moreover, the software content of

Chapter 5 is finally available-FPGA-based c2mif software design and VGA application I. Overview of the MIF File For a long time, do you want to talk about the design and application of the MIF file? Bingo cannot decide on his own. I have written so many, and I am a little tired. Finally, I bit my teeth and wrote it, because no one has ever written it, so I want to write it. If I don't take the ordinary path, I will open up this road, let the design

to reuse them after a long time. In fact, when a problem occurs, you can observe the existing debug-pin orIt is enough to find the root cause of the problem, without the need to introduce a new pin, and waste time merging and Par. 5. The timing of simulation is sufficient. With the design principle of clock synchronization, the functions of digital circuits can be verified through simulation. Simulation results and FPGA-Image is equivalent. Of course

Abstract: This paper introduces the working principle of the FIR extraction filter, focuses on the method of using xc2v1000 to implement the FIR extraction filter, and gives the simulation waveform and design features.Key words: FIR Filter extraction; pipeline operation; FPGA It is complicated to use FPGA to implement the extraction filter, mainly because FPGA la

actual hardware logical units in FPGA, such as Lut, D Trigger, Ram, etc, it is equivalent to the machine language in the software. During the implementation process, all the design units must be translated into the basic components of the target device. Otherwise, it cannot be implemented. The primitive can be directly used as an example in the design, which is the most directCodeThe input method is similar to the relationship between the Assembly La

How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparis

1 compared with ASIC, FPGA is a power-consuming device and is not suitable for designing ultra-low power consumption.2 in CMOS technology, the dynamic power consumption of the circuit is related to the charge and discharge of the gate and the metal lead. The general equation of capacitor current consumption isI = V * C * FV is the voltage, which is a fixed value for FPGA. The C capacitor is related to the n
