Improved Abstractions and Turnaround Time for FPGA Design Validation and Debug
Yousef Iskander, Cameron D. Patterson, Stephen Craven · 2011
Rapidly increasing FPGA density and complexity has heightened the need for higher levels of abstraction in validation and more rapid, focused approaches for design inspection. We present two methods of validating and debugging active, implemented FPGA designs running at target speeds. The first binds high-level software reference models directly to hardware enabling complex, automated, software-controlled testing scenarios, reducing the reliance on simulation. The second approach provides direct interactivity and visibility into a running FPGA design, enabling software-controlled breakpoints and arbitrary access to design registers. In-circuit breakpoints can be modified without the need to re-implement the entire design.
