Read capture timing analysis indicates the amount of slack on the DQ signals that are latched by the FPGA using the DQS strobe output of the memory device.

The TimeQuest Timing Analyzer analyzes read capture timing paths through conventional static timing analysis and further processing steps that account for memory calibration (which may include pessismism removal) and calibration uncertainties as shown in the following figure.
