How to set dual-purpose pin (nCEO) as regular IO in DSP Builder 18.1?

[DNEHL]

I have to use dual-purpose pin nCEO as an output pin in my project in DSP Builder. When I tried to compile my project I had such ERROR message

Error (176310): Can't place multiple pins assigned to pin location

Then I have added Quarus Prime Global Project Assignments block from Altlab library with parameters: Assignment name RESERVE_NCEO_AFTER_CONFIGURATION

and Value "Use as regular IO"

And I had the same ERROR message. What am I doing wrong?

Thank you, for your attention.

Hi Calvin,

Good day.

I have found the solution. It's correct to set Assignment's name CYCLONEII_RESERVE_NCEO_AFTER_CONFIGURATION

Thank you for your attention.

HI Calvin,

thanks for the answer, but it doesn't help me.

I'm trying to compile my project in DSP BUILDER in MATLAB, not in Quartus Prime. So I don't have possibility to open assignments menu. I'm using Signal Compiler block for this purpose.

Then I have added Quarus Prime Global Project Assignments block from Altlab library with parameters: Assignment name RESERVE_NCEO_AFTER_CONFIGURATION

and Value "Use as regular IO". But I had the same ERROR message: Error (176310): Can't place multiple pins assigned to pin location
