FIRRTL

FIRRTL (Flexible Intermediate Representation for RTL) is a specialized language used to describe and optimize digital circuit designs, particularly for hardware like computer chips. It serves as an intermediate step between high-level design specifications and the actual hardware implementation, allowing designers to analyze, modify, and improve circuit behavior efficiently. FIRRTL enables hardware developers to simulate, verify, and transform circuit designs before physically manufacturing the chip, helping ensure correctness and performance. Think of it as a universal blueprint that streamlines the process of turning complex digital logic into real, functioning hardware.
