New ContributorModifying and/or hiding interfaces based on component parameters?
I am working in Quartus Prime 26.1 with Platform Designer. I have created a _hw.tcl file for my new component. I would like to hide some interfaces based on the component parameters; for example, "Enable AXI-Stream Output" would un-hide an optional AXI-Stream interface.
I have tried using an elaboration callback (described here), but Platform Designer complains upon loading the _hw.tcl file, stating that the "Component Editor does not save TCL callbacks", and asks me to remove the callback.
I cannot replace ENABLE true with ENABLE [get_parameter_value ... ] either; this also causes an error.
Any help would be greatly appreciated!

You can do this, but not through ongoing Component Editor edits.
Platform Designer supports parameter-dependent interface visibility via ELABORATION_CALLBACK (see Section 4.7, “Control Interfaces Dynamically with an Elaboration Callback” in the link above).
The expected flow is: create the component once in Component Editor, then manually edit _hw.tcl for callbacks/custom Tcl (Section 4.3). If you reopen that customized component in Component Editor, your custom Tcl is overwritten (Section 4.3 note / 4.3.2).For loading/testing without “New Component”: Platform Designer discovers _hw.tcl from IP search paths during Discovery (Section 4.2). So put your component directory in IP Catalog Search Locations / SEARCH_PATH / user_components.ipx (Sections 2.6.5.1.x and 2.6.5.2), reopen Platform Designer, and instantiate from IP Catalog.
So in short: your approach is valid; use manual _hw.tcl + IP search path discovery, not repeated Component Editor edits.
