AtaiTec specializes in signal and power integrity modeling, simulation, and measurement correlation for IC, package, connector, cable, and board.
ADK (or Advanced SI Design Kits) is a collection of SI utilities; x2D is a 2D RLGC field solver that helps define the PCB stackup and trace width/spacing for impedance control; SI3D is a 3D SI tool that computes S parameters of complex 3D structures; ISD (or in Situ De-embedding) is meant to replace TRL calibration and help save SMAs and board material.
While the company has existed since 2005, primarily as a consulting company supported by a single client, the company changed to its current form in 2010. The tools are in part based on the long term experiences gained from their earlier work.
