NOTE: This Answer Record is part of the Xilinx MIG Solution Center (Xilinx Answer 34243) The Xilinx MIG Solution Center is available to address all questions related to MIG. 6. 0 - Issues can occur when generating/regenerating a MIG project with the same component name MIG 2. Rarely MIG calibration might fail after bitstream download. I am using the IP Interface "ddr4 sdram c1", with a differential input clock signal and a desabled debug signals for the controller. The Memory Controller supports the following calibration routines. 2 includes changes that positively impact the available read (Xilinx Answer 32320) MIG 3. Note: This Answer Record is a part of the Xilinx MIG Solution Center (Xilinx Answer 34243). Only way of connecting JTAG of VU13P then reseting MIG had effect. 6 is not production status IP. Manual Changes to Reduce Calibration Time in MIG v2. 4 to include this calibration stage. Following MIG Debug guid in <<Xilinx_Answer_60305_rev_2014_4. When you have the Complex calibration pattern selected, it is the final calibration value and overall has a smaller window than the Simple pattern. xbutil scan xbutil query. With the WebPACK version of ISim, this may actually take a couple of days. Usually XRT driver Hi, I am running DDR4 MIG tests as mentioned in XTP364. In WR_CMD state, the state machine waits for the MIG to be ready to accept commands. The description of these signals for every calibration stage is quite short so I was wondering if there Read calibration can be re-done at any time, but to run the calibration, 128 bits of the SDRAM's memory will be overwritten with the read calibration word. Please help me save my precious time if anybody has tried it So for Xilinx® boards use lspci utility. For information on other calibration stages, please see Note: Xilinx recommends existing Virtex-6 DDR2/DDR3 designs upgrade to MIG 3. Goal¶. Why Use Xilinx MIG DDR3? Xilinx MIG DDR3 provides a The purpose of this article is to help readers understand how to use DDR3 memory available on Neso using Xilinx MIG 7 IP core easily. Until this version is available, a manual work-around is provided below. This section will help you to define these limits (cu_bw & cu_latency) and find the optimal point which gives best results (maximum bandwidth with minimal latency). Topics. MIG arranges phasors, clocks, etc and small write-read test with the help of 200 MHz reference clock in calibration stages, which detailed information can be found via this Introduction The purpose of this article is to help readers understand how to use DDR3 memory available on Skoll using Xilinx MIG 7 IP core easily. MIG Usage To focus the debug of calibration or data errors, use the provided MIG Example Design on the targeted board with the Debug Feature enabled through the MIG UltraScale Xilinx Answer 43879 –7 Series MIG DDR3/DDR2 - Hardware Debug Guide 2 ChipScope Pro Tool The ChipScope™ Pro tool inserts logic analyzer, bus analyzer, and VIO software cores directly into the design. The Design Assistant provides useful design and troubleshooting information, but also points you to the exact documentation you need to read to help you design efficiently with MIG. Calibration passes successfully. Hello, I am designing a DDR4 controller with using Xilinx DDR4 MIG Ip Core. Calibration always passes. However, by modifying the following lines in ddr4_0_ddr4. 06Mhz (6664 ps). 7 and v1. When I program the device, the calibration fails in the first stage DQS Gate. It gives you a description of the Write Latency calibration stage and how to debug it. MIG status Note: This answer record is part of the Xilinx MIG Solution Center (Xilinx Answer 34243). and i can see the changed signal in the simulation. MIG status NOTE: This Answer Record is part of the Xilinx MIG Solution Center (Xilinx Answer 34243) The Xilinx MIG Solution Center is available to address all questions related to MIG. 0, Virtex-5 QDRII - Potential for small margin between the CQ and FPGA clock after stage 2 calibration for frequencies between 125 - 250 MHz MIG Virtex-6 (Xilinx Answer 34308) Pin-Out and Banking Requirements (Xilinx Answer 34544) Board Layout Requirements; MIG 7 Series (Xilinx Answer 51317) Pin-Out and Banking Requirements For information on the MIG 7 Series Debug Port and how to debug calibration failures and data errors using the traffic generator, see (Xilinx Answer 43879). We are now starting to use the BPI Flash method of The QDRII+ MIG performs self calibration after a system reset. So for Xilinx boards use lspci utility. Note: This answer record is part of the Xilinx MIG Solution Center (Xilinx Answer 34243). Whether you are MIG 7 Series DDR2/DDR3 PHY Only Design Guide - Xilinx This section of the MIG Design Assistant focuses on the ZQ Calibration defined by the JEDEC Specification, as it applies to the MIG 7 Series FPGA DDR3 designs. 7 This stage of calibration determines the read data valid window using a 128 long PRBS sequence This Answer Record details how to debug a failure during the Write Leveling stage of the Virtex-6 MIG DDR3 calibration process. I even triend with CAS=18 instead of 17 as mentioned somewhere on this forum. During the DQSFOUND stage of calibration, the different DQS groups are aligned to the same PHY_Clk and the optimal read data offset position is found with respect to the read I could use some help/pointers on what to look for when debugging a write calibration failure with 16 bit DDR3. 1 DDR3 calibration algorithm released in Vivado 2014. 9. (RZQ and ZIO) generated by the MIG tool (or EDK) to This section of the MIG Design Assistant focuses on the ZQ Calibration defined by the JEDEC Specification, as it applies to the MIG Spartan-6 MCB DDR3 designs. 2 Interpreting the results. I have checked the system clock and the reset signal. Indicates the DDR line calibration is complete. Write Leveling. e 625 ps). This debug interface is always Xilinx MIG 1. The compiled design is regularly tested in or regression-testing infrastructure. 5 Version Resolved and other Known Issues: See (Xilinx Answer 45195). Calibration is the first stage of MIG if you run the code. If it is correct then you'll want to look at PG150 for instructions on how to debug data errors after calibration. What is it you exactly want to know? 1. It fails on the first step "DQS Gate: Fail" with message "Pattern not found on GT_STATUS, all samples were 1. You can find more information about this IP through its product guide init_calib_complete NOTE: This answer record is a part of the Xilinx MIG Solution Center (Xilinx Answer 34243).
