| ### dv_base_reg_block |
| This class extends from uvm_reg_block and is used as the base class of all |
| auto-generated UVM RAL models for all IPs. This class provides a virtualized |
| `build(base_addr)` method that is used by the actual derived RAL models to build |
| the entire RAL structure. An instance of the RAL model is created in `cip_base_cfg`. |
| The model is however, locked by calling `uvm_reg_block::lock_model()` during |
| `cip_base_env::end_of_elaboration_phase()` to allow any customizations to |
| the RAL structures if needed during the`build_phase`. |
| |
| There are a few enhancement planned in future to this base ral model, that will |
| automatically be available in the extended IP specific RAL models through |
| inheritance: |
| * CSR exclusion automation: |
| We will add cip_base_reg and cip_base_field extensions to add attributes that |
| can be automated during the IP ral model auto-generation, which can be used to |
| exclude certain CSRs and fields from the CSR suite of tests. |
| * Support parameterized RAL model generation: |
| In future, we may have parameterized IPs that will have parameterized number of |
| CSRs / fields. Having this base class provides a path to support this. |
| |
| TODO add description for the other classes |
