A Charged Device Model (CDM) simulation method has been demonstrated to predict CDM fail current of receiving circuits with gate oxide connected to pad. This method involves inclusion of 20ps rise time edge into the stimulus. It was shown previously that this fast rise time component of the pulse can cause the gate oxide damage. The simulation method is intended as a schematic-level tool during pre-silicon design phase to deliver CDM ESD protection. Simulation results are verified by silicon results with qualification CDM test on package and Transmission-Line-Pulse (TLP) measurements on wafer-level.

Each new version of Wi-Fi standards offers more capabilities but also more complicated regulatory testing requirements. Deciding which capabilities to include and planning for pre-compliance testing can save multiple trips to the test labs and reduce time to market.

LTE and LTE-Advanced technologies are vulnerable to interference as well as jamming. However, strategies and techniques exist to address interference and guarantee coexistence with other services, especially in critical situations. Robust device design and thorough testing are essential for maintaining stable and efficient communication in high-interference environments.

It is common for people doing simulations to make a measurement of a similar set up to validate the simulation. The real issue is whether the tool user understands the problem well enough to capture the important features, and whether the user understands the tool well enough to use it correctly.
