    // Enables randomization of testbench / RTL build.
    //
    // Build randomization is achieved by passing `--build-seed <optional-seed>` on the dvsim
    // command-line. If not passed, the build is not randomized. Build randomization is achieved
    // in two ways. One of them is setting the pre-processor macro `BUILD_SEED` to the seed value,
    // which is done below. The SystemVerilog testbench sources can use the `BUILD_SEED` macro
    // value to set some design constants (such as parameters) upon instantiation. The `BUILD_SEED`,
    // if not set externally (by passing the --build-seed switch) is set to 1 in 
    // `hw/dv/sv/dv_utils/dv_macros.svh`. The other way is by passing the {seed} value to utility 
    // scripts that generate packages that contain randomized constants. These utility scripts can 
    // be invoked as a `pre_build_cmd`, wrapped within the `build_seed` sim mode in the DUT 
    // simulation configuration Hjson file. All forms of build randomization must be wrapped within
    // this `build_seed` sim mode. They will all use the same {seed} value, which allows us to 
    // deterministically reproduce failures. The `--build-seed` switch is expected to be passed 
    // when running the nightly regressions. The `seed` value set by dvsim is a 32-bit unsigned 
    // integer (unless specified on the command-line).
