WebClaims: 1. A method for calibrating a data valid window comprising the steps of: setting a base delay of one or more datapaths to a predetermined value; determining an optimum offset delay value for each of said one or more datapaths based upon actual memory accesses; and delaying a read data strobe signal based upon said base delay and said ...

WebThe controller must assert DFI_RDLVL_EN = 1 to initiate READ DATA EYE training. The Training IP sweeps the input tap delay, reads the data and compares it with the expected … WebThe PHY Data Macro is further described using an example Read Data Eye training. When the Read Data Eye Training is enabled, the PHY Data Macro receives a Training Control FSM that sends a memory write command to the Data Generation and Comparison Logic 400 which generates a known data pattern for output to DQ[7:0], DQS, and DQS# that is to be ... http://www.truecircuits.com/images/pdfs/TCI_DDRPHY_Datasheet.pdf port forward duckdns
