Calibration Error Associated With Qsys Simulation Model Settings - Calibration Error Associated With Qsys Simulation Model Settings Description This problem affects DDR3 products. Calibration failures have occurred in Qsys-based DDR3 designs with simulation model generation enabled. In failing cases, calibration does not complete successfully, and neither cal_success nor cal_failure is asserted. Resolution The work around for this issue is to not enable any simulation model when generating the synthesis file set. This issue has been fixed.
