KD Tech Stack

Automotive-grade optical semiconductor ICs for in-vehicle high-speed networking

Semiconductor Manufacturing Tres Cantos, Madrid 51–200 employees Founded 2010 Privately Held

KD designs integrated optoelectronic semiconductors for automotive—combining fiber optics, photonics, and electronics on a single chip to eliminate EMI and scale in-vehicle data rates from 1 Gb/s to 50 Gb/s. The tech stack (Verilog, SystemVerilog, Synopsys, Cadence, Questa, Vivado) and project focus (DSP/FEC algorithms, channel modeling, production automation) reveal a hardware-to-manufacturing transition: the company is scaling from R&D prototypes toward high-volume factory launch, with pain points centered on production capacity, automation optimization, and grant program delivery.
