Why does the Agilex™ FPGA EMIF simulation log have additional CALBUS messages?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 22.1, you may see these additional CALBUS messages during the simulation of the Agilex™ FPGA EMIF:

....

          4IOSS CALBUS Read -- addr=12107, data=00000000

          4IOSS CALBUS Read -- addr=06107, data=00000000

          4IOSS CALBUS Read -- addr=12107, data=00000000

          4IOSS CALBUS Read -- addr=06107, data=00000000

          4IOSS CALBUS Read -- addr=06108, data=00000060

          4IOSS CALBUS Read -- addr=06103, data=00000000

          4IOSS CALBUS Read -- addr=06107, data=00000000

          4IOSS CALBUS Read -- addr=12107, data=00000000

          4IOSS CALBUS Read -- addr=12108, data=00000060

....

 

Resolution

To disable those messages, revert to the previous IOSSM as described here:

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