Quatrus recognizes localparam struct field referencing as a hierarchical identifier referencing

typedef struct { int unsigned size_of_smth; etc. etc.; } param_t;   localparam param_t PARAMS = `{ size_of_smth : 4, etc : .... };   typedef logic [PARAMS.size_of_smth - 1 : 0] smth;  

Quartus shows the following error:

Error (10742): Verilog HDL error at some_file.svh(12): constant expression cannot contain a hierarchical identifier

PARAMS.size_of_smth is a constant, so I think it should be supported

Hi,

I'm using two versions:

Quartus Prime Version 18.1.0 Build 625 09/12/2018 SJ Standard Edition

and

Quartus II 64-Bit Version 14.0.0 Build 200 06/17/2014 SJ Full Version

 

Both of them produce the same error

 

Thanks,

Siarhei

Hi,

I apologize for the overlook on this case. We had an internal transition issue and the engineer overlooked this case on his plate. May I know if your request still outstanding? I can then decide on the next course of action for this case. Thank you.

Thank you for letting me know. Would you mind explaining to me what the workaround was? I can use that information for the verification at my end before I submit a ticket to engineering for the bug fixing or enhancement.
