Why is there a long delay between nCONFIG high and nSTATUS high on Intel® MAX® 10 devices?

Environment

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

    Due to nCONFIG behavior on Intel® MAX® 10 devices, when nCONFIG is held low after the power supply ramp time has completed, you may notice a power-on reset (POR) delay of up to 2.5 ms from nCONFIG high to nSTATUS high. This delay is not seen when nCONFIG is high on power up. Similarly, if a user manually pulls nCONFIG low after the device is in user mode to initiate a reconfiguration, you may notice a power-on reset (POR) delay of up to 2.5 ms from nCONFIG high to nSTATUS high. 

    Resolution

    This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software
