Comes up in situations like the following

// mystruct::the_struct declaration omitted

function automatic mystruct::the_struct do_stuff_function;
  input mystruct::the_struct a;
  begin
    do_stuff_function = a;
  end
endfunction

The class_var was removed from our UHDM with this change in Surelog chipsalliance/Surelog#2539, that was found when I reported chipsalliance/Surelog#2537.

Looks like this is issue in the Surelog itself. I've created issue in Surelog for this: chipsalliance/Surelog#2550

I've tested example that you reported in: chipsalliance/Surelog#2537, using typedefs directly from package gives vpiClassVar as variable type, but it should give vpiStructVar. When we import whole package, and then use typedefs, Surelog gives us correct vpiStructVar, e.g.:

package b;
  typedef struct packed {
    logic                one;
  } foo_bar_t;

endpackage : b

package aa;
  import b::*;
  function automatic foo_bar_t foo_bar;
    foo_bar_t y;

  endfunction : foo_bar
endpackage : aa

We'll wait for the Surelog issue to be resolved and decide what to do next.

Is this resolved ?
