While device-level models are usually sufficient for the controlled ESD environment of the factory floor, they are completely inadequate for system-level testing. The levels of ESD strikes from both voltages and currents can be much greater in the end-user environment.

To ensure system immunity we are going to review PCB design at various stages with our proprietary tool to identify gaps and suggest improvements to ensure ESD immunity at the PCB design level.

We have supported telecommunication, automotive and aerospace industry with such design reviews and actively involved in projects from these industries.
