Solutions

The boundary lines between traditional engineering disciplines have dissolved. As SerDes data rates increase, standard copper interconnects cease to act as passive conduits and instead behave as complex, wideband waveguides subject to frequency-dependent loss, phase delay anomalies, and dynamic multi-physics constraints. Traditional, automated EDA workflows often rely on single-frequency approximations and idealized boundary conditions that mask systemic structural vulnerabilities.

Forel Solutions provides an independent, physics-first deterministic engineering solution that bypasses software abstractions to resolve the physical anomalies driving hardware failure.
