Does the M20K content get automatically reset during Partial Reconfiguration if the persona bitstream does not use RAM/ROM initialization?

Environment

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

    When using the Partial Reconfiguration (PR) flow, if your persona bitstream does not use RAM/ROM initialization, the content of M20K internal memory will not be reset. Due to this, the previous data may be available in the M20K block. 

    Resolution

    Your persona bitstream must initialize the RAM/ROM.
