Can't record dynamic array in sequence item in QuestaSim 10.3a_1

[enchanter]

I am using QuestaSim 10.3a_1 and try to record a dynamic array in the sequence item. But it doesn't show in the waveform window. When I try to fix the array size and use uvm_field_sarray_int to record it, it works well and data show as expected in the waveform windows.

My code:

    # sequence item

    parameter int P_BIT_DEPTH = 10;

    rand int unsigned                   data_len;

    rand bit unsigned [P_BIT_DEPTH-1:0] data [];

    ...

    `uvm_field_array_int(data,     UVM_ALL_ON+UVM_UNSIGNED)

    `uvm_field_int      (data_len, UVM_ALL_ON+UVM_UNSIGNED)

    ...

    constraint c_data_size { data.size() == data_len; };

    constraint c_data_size_order { solve data_len before data; };


    # Sequence body task

    start_item(req);

    if (! req.randomize() with { data_len == 2; })

       `uvm_error(tID, "Can't randomize ingress packet")

    finish_item(req);

 

req.sprintf() always prints the right information, no matter data is dynamic or static array.

Recoding dynamically sized arrays and queues requires the the vsim -classdebug switch. Use of the `uvm_field macros are not required. Check the reference manual for other options related to the "add wave" command regarding dynamic memories. For more help, please contact Mentor Support.
