  2. Hi, I am trying to run uvm code using qverilog command using shell script as : qverilog \ -timescale "1ns/1ns" \ -mfcu \ +acc=rmb \ +incdir+../../../../../src+../sv\ ../../../../../src/uvm.sv\ $TB_HOME/tb_top.sv \ -R \ -sv_lib ../../../../../win32/uvm_dpi -supress 2181\ +UVM_TESTNAME=$TEST_NAME\ -c \ -do "run -all; q" \ -l questa.log I get the error as : ** Error: ../../../../../src/uvm_pkg.sv(27): near "package": syntax error, unexpected IDENTIFIER, expecting class ./examples/tb_top.sv: line 1: ///*-----------------------------------------------------------------: No such file or directory ./examples/tb_top.sv: line 2: //File: No such file or directory Where starting lines of tb_top are commented, but it is expecting file names there. Please help. Regards, Chandan
  3. 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.
