OptEM Connector
OptEM Connector is used by engineers developing cables and connectors for systems with high-speed data transmission.
Connector development engineers are typically concerned with impedance control. To minimize reflections designers must compensate for sections with lower impedance while keeping in mind the requirements for signal speed and frequency range.
Using OptEM Connector a designer can model cross sections and observe L, R, C, G, and characteristic impedance (Zo) results, as well as create transmission line models for analyses like TDR, ground bounce and near/far end crosstalk simulation.
Cable designers are often concerned with the lossy and frequency-dependent characteristics of long wires. OptEM Connector assists with the detailed analysis of conductor and shield losses resulting from skin effect and proximity effect.
System designers require connector and cable transmission line characterization for high-speed simulation to properly account for time delays, impedance mismatch, and additional crosstalk effects caused by connectors and cables within their system.
DXF Input & Geometry Extraction
OptEM Connector reads DXF CAD files from which multiple cross-section regions can be captured and extracted all at once in a matter of seconds.
The material properties and conductors within each cross section are assigned using object definitions. An object definition includes the type of material, on-screen color, naming rule, plating, and conductor type (signal or ground). Modeling efficiency and flexibility is enhanced through editing features.
Profile Modeling
Often the profile of a connector is also drawn on the same sheet as the cross sections. A complete model of a connector is created simply by assigning each extracted cross section to a position within the profile.
Assigning each cross section to a position in the profile allows OptEM Connector to automatically model the non-uniform geometry located between cross sections and greatly increases the overall accuracy of the final circuit simulation.
System Modeling & Analysis
OptEM Connector provides a schematic capture facility which allows connectors, cables, and other models to be assembled into a system model. A circuit analysis of the entire system is then performed.
