In reply to MahD:

Assuming the implementation of the built-in array locator methods have better performance, set_register task could be like

    // ---------------------------------------------------------------------//
    task automatic set_register(string block_name, string register_file, 
                    string register_name, string field_name, 
                    bit [3:0] RegisterValue);

        uvm_reg_block   reg_model;
        uvm_reg_block   reg_block;
        uvm_reg         regs[$];
        uvm_reg_field   fields[$];
        uvm_status_e    status;

        uvm_reg register[$];
        uvm_reg_field field[$];
        string field_full_name;
        string reg_full_name;

        reg_model = m_env.m_ral.lckg_ral;
        reg_block = reg_model.get_block_by_name(block_name);
        if (reg_block == null)
            `uvm_fatal_context("set_register", "lckg_ral block not found", uvm_root::get());

        reg_block.get_registers(regs);
        reg_block.get_fields(fields);

        field_full_name = {reg_block.get_full_name(), ".", register_name, ".", field_name};
        reg_full_name   = {reg_block.get_full_name(), ".", register_name};

        register = regs.find with(item.get_full_name() == reg_full_name); 
        field    = fields.find with (item.get_full_name() == field_full_name);
        // Check for the size of register and field
        if(register.size != 1) 
            `uvm_fatal_context("REGISTER_NAME", "register name doesn't exist!!!", uvm_root::get());
        if(field.size != 1) 
            `uvm_fatal_context("FIELD_NAME", "field name doesn't exist!!", uvm_root::get());

        field[0].set(RegisterValue);
        register[0].update(status);
    endtask

For the nested foreachs, you could use the following equivalent one, I don’t think you will gain a performance, but it will be more readable.

 foreach (cfg.paths[clk_i, clk_o, s1, s2, s3, s4]) begin
      set_register("boston_lckg_lckg_csr", s2, s3, s4, cfg.paths[clk_i][clk_o][s1][s2][s3][s4]);         
 end

Note: I’ve partially compiled the code, to compile it fully I need the whole environment setup, but I guess you get the idea.
