SystemVerilog [1] UVM [2] class-based testbenches have become as complex as the hardware under test, and are evolving into large object-oriented software designs. The usual RTL debugging techniques must be updated to match this new complexity. Debugging tools are addressing these complexities, but this article will describe techniques and approaches that can be used to help debug these complex environments without advanced debug tools.
INTRODUCTION
Debugging large testbenches has changed recently. The testbenches are larger than they used to be, and they are more like software than they used to be. In addition, the testbench language features use object-oriented constructs,
