non-uvm message compliant, grep during report pahse.

[Kameshwar Rao]

is there way to search for the non-uvm compliant error message such as "ERROR - CSI Rx BFM "  during the uvm report pahse of uvm environment?

if we see this string error count variable need to be incremented and finally display test case is failed in log file.

The easiest is perhaps to run a post-processing script. If you insist you want to do this within simulation domain, try:

 

1. Your tool may have some API to get you all $error (Assuming that error originated from a $error and not plain $display)

2. You could do a "grep -c ERROR" and another grep -c UVM_ERROR and calculate the difference and increase the count. There are some tiny little details to get there as plain old Verilog's $system won't allow return values to be easy to access within Verilog. You could always write your own C layer around, but is it really worth it? Maybe a good task for an intern if you have access to!

1. uvm_report_server svr;
    reg [31:0] csi2_err_cnt_mem[0:1];

 

2. initial begin

        csi2_err_cnt_mem[0] = 0;

        csi2_err_cnt_mem[1] = 0;

        

        wait for events; //i mean after all bfm models are got dropped.

 

        svr = _global_reporter.get_report_server();
        svr.summarize();

 

        //Here I grep the non-uvm error message count into a file.
        $system("grep \"ERROR - CSI RECEIVER BFM\" ${SIM_RUN_DIR}\/${TC_TESTCASE_DIR}\/nccoex\/..\/result\/\*.log  \| wc \-l \> csi2_err.txt");

 

        //Read the file contents into two-dimentional memory.

        $readmemh("csi2_err.txt",csi2_err_cnt_mem);

 

       //adding the uvm_error and non-uvm_errors and comparing with value zero.
        if((svr.get_severity_count(UVM_FATAL) + svr.get_severity_count(UVM_ERROR)) + csi2_err_cnt_mem[0] == 0)
          begin   
            if(svr.get_severity_count(UVM_WARNING)==0)
              `uvm_info("final_phase", "STATUS: UVM TEST PASSED", UVM_LOW)
            else
              `uvm_info("final_phase", "STATUS: UVM TEST PASSED with WARNINGS", UVM_LOW)
            print_pass();
            $write("** UVM TEST PASSED **\n");
          end
        else
          begin

              print_fail();
             $write("** UVM TEST FAILED **\n");

          end


Note-1:  the above mention code is working fine for me.

 

Note-2: Srini, Thanks for reply.
