The Arithmetic Reaches Into Physical Design

FMA combines multiplication and addition with one final rounding, so exponent alignment, partial products, normalization, exceptions, precision, and IEEE 754 behavior interact throughout the datapath.

Wire delay, fanout, clocking, placement, cell libraries, process corners, and power grids then reshape the logical design. Engineers must iterate between physical results and RTL architecture.

A Cadence seat can cost around $80,000 per year, while foundry rules and corporate practice often remain closed. That structure concentrates the experience required to turn a correct module into manufacturable silicon.

Universities, chip companies, foundries, and open-tool teams can publish verified arithmetic blocks with reproducible physical flows. Open FMA IP can become infrastructure for an entire generation of independent AI-chip builders.
