Why do I see data corruption when I use Intel® Arria® V GX and data transfer happens across the Global clock and Regional clock path?

Environment

  • Intel® Quartus® Prime Standard Edition
    • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You may see the data corruption at data transfer across the Global clock and Regional clock path upon fitter dependency.

    Resolution

    Use set Uncertainty to 400ps across Global clock and Regional clock Quad region as a workaround

    • Use set Uncertainty to 400ps hold timing from Regional clock to Global clock path
    • Use set Uncertainty to 400ps setup timing from Global clock to Regional clock path.

    Please do not use the path at global clock resource across different Quad region.
