AR# 40578

MIG 7 Series v1.1 - Fixed latency mode is not supported for QDRII+ designs

Description

I can enable the Fixed Latency Mode in MIG 7 Series v1.1.

Is Fixed Latency Mode supported?

Solution

No, Fixed Latency Mode is not supported in MIG 7 Series v1.1, but is supported starting with the 13.2 release.

When using Fixed Latency Mode, if calibration results are less than the selected fixed delay value, then MIG will add delay to match the fixed value.
