Interface to User Logic in Qsys

I am porting an old NIOS II design from Quartus II 12.1 with SOPC Builder to Quartus Prime 20.1 Standard with Platform Designer. In our old design we have a few "Interface to User Logic" components...

Is this your own custom component? If so, use the Component Editor (accessed from the IP Catalog in Platform Designer), which is basically a wizard, to point to your HDL file(s) and set up the interface(s) (Avalon slave as you mention, which is now referred to as an "agent" interface in the newest versions of the software).

Thanks for the reply!

Yes, the components(there are 5 different) were made by a colleague of mine, ten years ago, they only appear as interface to user logic, and a .vhd file.
I tried going through a component, but there are some discrepancies where I am not sure what to do exactly.
E.g. I have a component where the data is inout, but I have to do a separate read and write data line in Platform Designer, I'll try to attach some screenshots of the component from SOPC and my try of implementing it in PD.

Bear with me, I am a novice at Quartus, and a bit under time pressure
