Do I need to perform skew matching including package per-pin skew and PCB delay when I migrate the device with different package delay with Intel® Agilex™ FPGA EMIF IP ?

Environment

Bug ID: 18017147271

Quartus Edition

Intel® Quartus® Prime Pro Edition

Version Found: 21.2

BUILT IN - ARTICLE INTRO SECOND COMPONENT

Description

You do not need to perform package per-pin skew when you plan to migrate the device with different package delay because migratable devices with different package delays and calibration being able to compensate for the variation so only matching the PCB trace delays is required for full frequency specification operation.

Resolution

Follow these guidelines:

Include package length in skew matching for FPGA device with no migration = Required
Include package length in skew matching for FPGA devices with migration = Not Recommended

Resolution
