Register Field Modeling

Beginner~60 min

Problem statement

How do you model multiple register fields with different access policies, reset values, and bit positions using uvm_reg_field?

Learning objective

Model a multi-field register in which every uvm_reg_field's LSB position, width, access policy and reset value matches the RTL bit map.
