IP: Altera Unique Chip ID

Why does the Intel® Stratix® 10 Chip ID IP core read all zeros in user mode?

Description

When the Intel® Stratix® 10 Chip ID IP core is taken out of reset in user mode, you may see no output on the 'chip_id' port even after the assertion of 'data_valid' signal. This may be seen with designs compiled in Intel Quartus® Prime Pro software version 17.1. 

Workaround/Fix

To read out the unique chip ID from Intel Stratix 10 devices

  • Assert reset initially to reset the chip ID IP core.
  • Trigger a high -> low transition on the 'readid' port to initiate one read command to the IP core.
  • Use the 'readid' port to trigger multiple reads in user mode.

This problem has been fixed in Intel Quartus Prime Pro software version 18.0.
