Start using AXI VIP with some basic understanding of UVM Posted by VIP Experts on March 10, 2015 Recently I worked with a user who was responsible for verifying an AXI interface. The system's microprocessor has access to the AXI DMA through the AXI Lite interface. In this other example the script in the MODE simulation also saves the data in a file and shows how you can import this data into Interconnect and model the modulator in a circuit simulation. Defining peripherals. This is a point to point interconnect and overcomes the limitations of a shared bus protocol in terms of number of agents that can be connected. In the search field, type gpi to find the AXI GPIO IP, and then press Enter to add the AXI GPIO IP to the design. But what is JTAG, and how can it be used to benefit organizations in diverse industries across all phases of the product life cycle?. AXI VDMA implements a high-performance, video-optimized DMA engine with frame buffering, and two-dimensional (2D) DMA features. Connect the input M_AXI_GP0_ACLK of the ZYNQ7 PS to its output FCLK_CLK0 (these steps are explained in detail in the tutorial 8 - First use of the Zynq-7000 Processor System on a Zynq Board).

UVM in Systemverilog: Learn The Architecture & Code Your VIP 3. But before jumping into writing a device driver of your own, allow me to share rule number one for writing drivers for Linux: Never write a device driver for Linux. Add the AXI Timer and AXI UART Lite IPs; Run connection automation on both of them. Therefore the address decoder you are looking for is inside the AXI interconnect. Hence, any peripheral accessed via the M_AXI_DC bus must have an address greater than 0x8000_0000 while any peripheral accessed via the M_AXI_DP bus must have an address less than 0x8000_0000. The course covers frequently used features with the goal of giving users a basic understanding of the solver algorithms, and simulation workflow. Sadri, Zynq Training. Add the Timer and UART. The AXI bus is the most widely used AMBA interface. This ambiguity is intentional. This is a point to point interconnect and overcomes the limitations of a shared bus protocol in terms of number of agents that can be connected.

It "connects one or more AXI memory-mapped master devices to one or more memory-mapped slave devices. 8, before the slave can lower S_AXI_ARREADY since S_AXI_ARREADY is required to be a clocked signal. pdf that tells you all about that LogiCore. 4) Select GPIO under axi_gpio_1 and select leds_8bits in the drop-down box and hit OK. Select S_AXI and click OK. We have monitored the M_AXI_GPx channel with Chipscope checking that the VDMA is initialized without problems. If all 4 AXI ports on the sub-switch are accessing pseudo channels in the adjacent sub-switch, then the AXI bandwidth is reduced by half, due to the switch arbitration of the 4 AXI ports, through the 2 adjacent sub-switch AXI interconnect paths. Older versions of the MicroBlaze used the CoreConnect PLB bus. Michael In the last article , we introduced AXI, the Advanced Extensible Interface, part of the ARM AMBA specification for SoC design. xmp and 'Create Top HDL'.
