MAX10 ADC - getting it to simulate in Modelsim

Hi,

I'm setting up a new project - actually a rework of a 7 year old project were we had massive tools problems with the ADC, some of which I think were specific to Quartus 17.

I have regenerated the ADC IP in Quartus 18.1.
I have manually created the simulation in Modelsim 10.5b.

I have added all the ADC files I can find to the Modelsim project, as shown in the attached screenshot.
When I run the simulation, all the ADC outputs are floating.

Any clues as to what I am going wrong, please?

I tried running the msim_setup.tcl from the Modelsim command line, but this made no difference.

Searching this forum, I wonder if it has something to do with fiftyfivenm_adcblock_primitive_wrapper.v, but the solution eludes me, since I have compiled this.

Attached:
screenshot of my modelsim project, the generated IP code, and my vhdl which instantiates the ADC.

Thanks,

Rob
