Verilog is source code that becomes silicon. A Verilog review is how a litigation team examines what a chip design actually does: not the marketing block diagram, but the register-transfer-level logic that was synthesized into the accused semiconductor. That makes Verilog review a specialty inside a specialty, sitting at the border of software analysis and hardware engineering.
The short version: Verilog appears in semiconductor patent, trade secret, and licensing disputes, where the question is what logic a chip implements and where that design came from. Reviewing it requires digital design engineers who understand concurrent hardware semantics, synthesis, and the relationship between RTL, netlists, and fabricated silicon.
Where Verilog cases come from
Semiconductor patent litigation reaches Verilog whenever asserted claims read on how a chip works internally: pipelines, memory controllers, bus protocols, signal processing blocks. Trade secret cases follow chip design teams, because RTL embodies years of accumulated engineering judgment and travels too easily with departing engineers. And semiconductor IP licensing generates its own disputes: whether a licensed core was used beyond its terms, modified, or copied into a house design.
What a litigation-grade Verilog review looks for
- Concurrent semantics. Verilog describes hardware where everything happens at once. A reviewer who reads it like sequential software will mischaracterize the design, a mistake we see and one that cross-examination punishes.
- Claim mapping to RTL. Tracing patent claim limitations to specific modules, always-blocks, and signal paths, and understanding what survives synthesis into the shipped netlist.
- Design provenance. Module structure, naming, parameterization style, and repository history that distinguish independent design from derived work.
- Verification artifacts. Testbenches, assertions, and simulation waveforms, which often document what the designers understood their logic to do.
- The netlist connection. Relating RTL to gate-level netlists and, where needed, to silicon-level reverse engineering of the fabricated part.
