Axi quad spi constraints I am having a problem following the recommendations in The product guide for the AXI Quad SPI core V3. The Dual/Quad SPI is an enhancement to the standard SPI protocol (described in the Motorola M68HC11 data sheet) and provides a simple method for SPI met timing by a wide margin without the I/O constraints, so I started adding them back in and it fell apart after adding an unrelated interface. There are 2 SPI interfaces, one is connected to the STARTUPE3 block and the other is connected to the SPI1 (io0_1_, io1_1_, io2_1_, io3_1_, and ss_1_* ports). Jul 21, 2025 · To understand how the constraints are added, it is important to understand the logic structure around the clock and data in AXI Quad SPI flash memory. 16 hours ago · Hi, I'm trying to use AXI Quad SPI IP 3. The "Resource Utilization for AXI Quad SPI v3. The SPI_1 ports are constrained the way shown in STARTUP is Disabled. Fixing those constraints allowed SPI to meet timing. Jul 21, 2025 · The system-level constraints mentioned in Constraining the IP section have to be added in the top XDC files. The following steps briefly describe the erase, write, and read command sequence for SPI flash. The rest of the constraints are take Jul 21, 2025 · AXI Quad SPI LogiCORE IP Product Guide (PG153) - 3. Processor System Design And AXI AXI Quad SPI Liked Like Share 3 answers 4. Place and route takes much less time to complete as well. This IP generates a "perfect" SPI waveform, with setup and hold times both being nominally half the clock period. This primitive has The AXI Quad SPI core, when configured in standard SPI mode, is a full-duplex synchronous channel that supports a four-wire interface (receive, transmit, clock, and slave-select) between a master and a selected slave. 2) IP from Xilinx, running in Standard rather than Quad mode. Introduction The AXI Quad Serial Peripheral Interface (SPI) core connects the AXI4 interface to those SPI slave devices that support the Standard, Dual, or Quad SPI protocol instruction set. The numbers mentioned are arbitrary values and update them according to your design. My goal is to use spi signals on J7 so in the ip configuration i selected shield spi board interface and I've uncommented the ChipKit SPI entri Nov 29, 2024 · The SPI IP block I'm using is the AXI Quad SPI (3. <p></p><p></p>The application is to be able to reprogram the configuration Flash memory device. The project targets an Artix 7, and I'm using vivado 2018. The AXI Quad Serial Peripheral Interface connects the AXI4 interface to those SPI slave devices which are supporting the Dual or Quad SPI protocol along with Standard SPI protocol instruction set. This core provides a serial interface to SPI slave devices. Learn how to add board-specific constraints for AXI Quad SPI Core and integrate them into your project effectively. 2 (PG153). Logic Structure Note: Refer to UltraScale FPGA Post-Configuration Access of SPI Flash Memory using S The AXI Quad SPI IP core, when configured in standard SPI mode, is a full-duplex synchronous channel which supports a four-wire interface (receive, transmit, clock and slave-select) between a master and a selected slave. When configured in Dual/Quad SPI mode, this core supports additional pins for interfacing with external memory. Jul 21, 2025 · All SPI transactions in master mode depend upon commands supported by a slave device connected to the AXI QUAD SPI core. 2 PG153, page 15. I can get the SPI to successfully transfer data in LOOPBACK mode but when I run without loopback, with a scope I do not see the SCLK move on pin 3 of SPI connector J6 at all. STARTUP is enabled: The frequency of operation of AXI-QSPI is affected when a STARTUP primitive is enabled. These additional pins are used while transmitting the command Jul 21, 2025 · In dual quad mode, the STARTUPE3 primitive is enabled. 2 in my Cora Z7 based Vivado project but seems to don't work and I have some doubts I'm setting up all correctly. The Dual/Quad SPI is an enhancement to the standard SPI protocol (described in the Motorola M68HC11 data sheet) and provides a simple method for Oct 1, 2020 · I now added a quad_axi_spi board component with SPI port J6. Refer to the respective SPI slave data sheet for the supported commands and mode (standard/Dual/Quad). 3; I'm trying to use the constraints recommended on pages 89-90 of PG153. The following figure gives an idea of the logic structure: Figure 1. My code is based on the Xilinx \embeddedsw\XilinxProcessorIPLib\drivers\spi_v4_4\examples. The AXI Quad SPI core, when configured in standard SPI mode, is a full-duplex synchronous channel that supports a four-wire interface (receive, transmit, clock, and slave-select) between a master and a selected slave. 77K views Jul 21, 2025 · In the current project directory, a new project called <component_name>_example is created. This directory and its subdirectories contain all the source files that are required to create the AXI Quad SPI example design. 2 English - The core connects the AXI4 interface to SPI slave devices which support the standard, dual or quad SPI protocol. The Dual/Quad SPI is an enhancement to the standard SPI protocol (described in the Motorola M68HC11 data sheet) and provides a simple method for . 2" still shows results with s_AXI4_aclk clock at 100Mhz and ext_spi_clk at 50Mhz, clearly contradicting the information on AXI Quad SPI V3. ubptx rnkc wlsgsk bbelopg xvzppu zozysrt edpqksw zhuosl kakt dkwu kjpbu bfejxm djkz tydlyo aoytv
