title="Modeling"]<p>The goal of our modeling program is to equip a signal integrity group with unimpeachable 3D EM models and material properties that achieves less than 2 Ohms measure-based TDR to simulation and Extreme Signal Integrity performance and a 2% impedance tolerance for Stripline transmission lines (WRT has a process to exceed the 5% even for multi-laminate construction).  </p><h4><u>Material Identification Program</u></h4><ul><li>WRT has a highly proprietary material ID methodology using a host of structures that are used to fit material ID in X-Y and Z PCB orientation.</li><li>Material Identification and modeling is EDA-centric, fitting the models in a specific EDA tool.   There is a pre-fabrication review phase and post-verification phase that is measure-based.</li><li>Construction of a reduced Channel Modeling Platform that focuses on material ID is core to this activity.   There is a partial set of verification structures that are used to verify the models</li><li>Cross-sectional analysis (included in CMP) and pcb fabrication verification is also done</li><li>Measurements of the CMP undergo comprehensive S-parameter quality checks which proceeds careful calibration</li><li>Measurements, Comprehensive model material ID fit reports, PCB libraries of the CMP, and measurement to simulation correspondence examples are included in the final report</li></ul><p>See part of an example report <u>here.</u></p><h4><u>2D, 2.5D, and 3D Simulations to 90GHz</u></h4><ul><li>The Material Identification program is a pre-requisite of this

your requirements with the WRT ESI Team:</p><ul><li>Prior to the meeting we will typically establish a mutual NDA, send email to <a href="mailto:jim@wildrivertech.com">jim@wildrivertech.com</a> to commence this process</li><li>Please be prepared to discuss the high-level objectives, rough schedule, what level of future-proofing is required, and ancillary requirements (cost, production volume, mechanical or thermal requirements, etc.).</li><li>We also like to identify the level of signal integrity challenge, operating bandwidth, rise/fall times, signal integrity margins, etc. If you do not
