Practical articles on AI-generated RTL, verification limits, and hardware design.

• Why use HDL Arena instead of a generic AI chat tool?

  Blind RTL comparison, practical engineering review, and approved learning workflows—plus the data-handling and verification limits to understand first.

• Why RTL generation is different from just coding

  Concurrent hardware, finite widths, clocks, and cycle-level contracts: why convincing HDL needs more than a working algorithm.

• How compile and synthesis is done in our flow

  Follow original RTL through isolated Icarus compilation and generic Yosys synthesis—and understand what a passing check does not prove.

• How ranking works

  Seeded starting ratings, the default 1000-point baseline, and blind local votes: a practical guide to the Elo-style leaderboard.

• How to write best prompts for best RTL

  A reusable hardware specification template, a stronger multiplier prompt, and the edge cases worth spelling out before generation.

• DSP, memory or other RTL blocks: how do they work?

  From signed MACs and pipelines to memories, FIFOs, counters, and state machines: the circuit patterns behind useful RTL.
