Label:looking at the DDR manual for a while, feeling a little bit about it, want to actually board debugging, but the lab is not much usable development Board, took a piece of ZYNQ board looked, DDR does have, but has integrated the controller, and the controller is placed on the PS end, PL can only be accessed through the Axi interface. But the other two development boards also like this, simply use Axi to control it, just can also review the Axi again. A brief introduction to the ZYNQ, its f

A: PrefaceA lot of me as a beginner. PCIe hardware engineers will encounter such a problem, see a lot of PCIe-related information, or can't figure out how to use this thing. So we turned on the Core_generator tool on the ISE, generated a PCIe IP core, emulated the example design with Modelsim, and analyzed it as if the protocol part was understood more deeply. As for how to use, hehe ...Of course, most hardware engineers are self-motivated! So we went online to find information, found a

Of course, this is only my opinion, because it seems that many people in the same major do not talk about FPGA application systems, I have always insisted that it is just as wasteful as using P4 CPU to make digital TVs. FPGA is a treasure horse, you should not pull a car to grind the surface, the battlefield is your best desti

specified devices can be found in the relevant manuals of Altera or Xilinx. Implementation Based on cyclic queue One way to implement FIFO caching is to add a control circuit to the register file. Register files use two pointers to arrange registers like a cyclic queue. Write poniter points to the head of the queue; read poniter points to the tail of the queue ). Each read or write operation moves the Pointer Forward. 8-operation 2 of the word loop

TCL IntroductionVivado is the latest Xilinx FPGA design tool that supports the development of FPGA and ZYNQ 7000 in the 7 series. Vivado can be said to be a completely new design compared to the previous Ise design suite. Whether from the interface, settings, algorithms, or from the user's idea of the requirements, are brand-new. Look at Vivado, Tcl has become the only supported scriptTCL (read as Tickle) was born in the 80 's University of California

Altera's RAM initialization file format is MIF and hex. Quartusii's own RAM initialization tool facilitates the generation of initialization files.Xilinx's RAM initialization file format is the Coe, and in Vivado the software turns the Coe file into a MIF file. Xilinx and Altera MIF file formats are not the same. The Xilinx MIF file is the final valid initialization file. You can use the Memory Editor editi

The Axi full name advanced Extensible Interface is an interface protocol that Xilinx introduced from the 6 series FPGA, primarily describing the way data is transferred between the master and slave devices. Continue to use in Zynq, version is AXI4, so we often see AXI4.0,ZYNQ internal devices have Axi interface. In fact, Axi is a part of the AMBA (Advanced microcontroller bus Architecture) proposed by arm, a high-performance, high-bandwidth, low-laten

Most FPGA developers are accustomed to graphical interfaces (GUIs). The GUI approach is easy to learn and provides a one-click process for small projects. However, as FPGA projects become more complex, in many cases GUI tools hinder productivity. Because GUI tools do not provide sufficient flexibility and control over the entire development process. On the other side, the GUI tool itself consumes a large amount of CPU resources and memory.choice of scripting languageThe most commonly used in ICS
