Quartus Prime v18.1 : Arria 10 DDR4 Controller & PHY

[bjwinter]

This error appears when I attempt to Synthesize a design containing a DDR4 Controller and PHY combination in an Arria 10 target.

Error (129029): Input port RZQIN on atom "ddr4:u_ddr4|ddr4_altera_emif_181_qumtwji:emif_0|ddr4_altera_emif_arch_nf_181_ebhl3ui:arch|ddr4_altera_emif_arch_nf_181_ebhl3ui_top:arch_inst|altera_emif_arch_nf_oct:oct_inst|cal_oct.powerup_oct_cal.termination_inst", which is a twentynm_termination primitive, is not connected to a valid source

The error indicates an issue with auto-generation of the IP, where the above input is not being driven.

NOTE : I have submitted the error dump via the in application request.

Any assistance on this matter would be greatly appreciated!

Hi Bradley,

You need to make a connection in your top level design for the instances.

• OCT
• Reset

The EMIF_pll_ref_clk cannot be hooked up to internal PLL pin.

It's must be connected to external pin.

There are several dq pins that are not fit in the design.

So I let the Quartus to Auto Fit the signals pin location.

I will share the design that I've edited.

I hope it's working just like you wish.

Thanks,

Adzim
