Wrong mapping of overloaded functions in Quartus 24.1 Pro

Hi, I'm stuck with a weird error in the new Quartus 24.1.0 Build 115 SC Pro Edition. I defined two functions with the same name but a different signature: pure function from_my_bool_a(data :...

Hi,


The problem at line 28 variable data_v : std_logic_vector(size-1 downto 0); where the size can't fetch a proper value which cause the unconstrained array type issue.


At lines 11 and 27:

pure function from_my_bool_a(data : in my_bool_at; size : in integer) return std_logic_vector


swap the data : in my_bool_at and size : in integer like below:

pure function from_my_bool_a(size : in integer; data : in my_bool_at) return std_logic_vector;


The synthesis will pass.


Thanks,

Regards,

Sheng

Thanks for the workaround. But I'm afraid I cannot apply it in my case.

Almost all types in my project and the conversion functions like from_my_bool_a are generated by a code generation tool. So I cannot simply change the parameter order.

BTW: The same code works flawlessly with Quartus 22.1 Standard. That is why I am suspecting a problem with the compiler.
