FIRRTL (Flexible Intermediate Representation for RTL)

FIRRTL (Flexible Intermediate Representation for RTL) is a specialized programming language used to describe digital hardware designs, like those in chips or processors. It acts as a common intermediary, translating complex hardware specifications into a standardized form that computer tools can analyze, optimize, and transform. This flexibility allows designers to verify functionality, improve performance, and generate efficient hardware layouts from high-level descriptions. Essentially, FIRRTL streamlines the process of turning abstract hardware ideas into detailed, implementable designs, making hardware development more efficient and accurate.
