Calibration Error Associated With Qsys Simulation Model Settings

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT

Critical Issue

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.
