Error(18948): Error message received from device: Detected internal error.


You may see this error in Intel® Quartus® Prime Pro Programmer when trying to configure an Intel Stratix® 10 device with a design that contains any of the following features/IP and the reference clocks for these features/IP are not running and at correct rates before and during configuration.

  • Transceivers (including PCIe HIP)
  • External Memory Interfaces (EMIF) 
  • Hard Processor System (HPS)
  • High Bandwidth Memory 2 (HBM2)
  • Secure Device Manager (SDM)


Ensure that the reference clock required by these features is present before and during configuration, otherwise configuration may fail.
