Stratix 10 HPS DDR4 EMIF placement error
- 2 years ago
Hi ,
Sorry for the delay in getting back, was scrutinizing the pins with the team and doing testing on the Quartus fitter
To resolve the fitter error on the IO lane and tile, you will need to remove the pin assignment CLK_50_B2L in pin planner and let the fitter reassign it automatically (alternatively edit the qsf file, and remove the constraint "set_location_assignment PIN_BA27 -to CLK_50_B2F"
This is some others restrictions that was put in place in the requirements on banks 2M, 2L, 2N (other than the ones mentioned in the KDB )
On quartus 19.4 , probably I will check it later , as the KDB mention 19.1 and below, but i suspect additional requirements been put in place as well.
Thanks
Regards

Just a follow up on the question, I've tested Quartus 19.4 as well, the design can be compiled without any changes or restrictions. However it also does not have any upgrade IP prompt thus I suspect the new IP version have further pin requirements implemented on top of the KDB mentioned in above post (anyway the original design RZQ and PLL already in bank 2M ) in Quartus 20.x onwards.
Thanks
