Example 2

<waivers version="7">

    <waiver name="waiver_elements">
        <status>DISABLE</status>
        <description>
          Disable SVTB rule 29.1.4.1 failing

        </elements>
    </waiver>

</waivers>

All failures of SVTB.29.1.4.1 will be disabled for the following file, because all modules declared in the file match the naming pattern.

test.sv

module test_1();
    /* module code */
endmodule;

module test_2();
    /* module code */
endmodule;

No failures of SVTB.29.1.4.1 will be disabled for this file. The waiver will be ignored because not all modules declared in the file match the naming pattern.

test.sv

module my_test_1();
    /* module code */
endmodule;

module test_2();
    /* module code */
endmodule;
