TIE+ 2018 Topics

 

The TIE+ subject of the 2018 edition will be focused on the simulation for signal and power integrity of electronic assemblies (single board and multi-board systems).

The need to incorporate such specialized electromagnetic simulations in to the PCB design flow is determined by the fact that, at high frequencies associated with digital data transmissions, the interconnect can be no longer considered an ideal electrical connection and the parasitic elements have to be taken in to consideration.

A general overview of the topics of interest for this disciplinary area is provided below.

> Transmission line theory
— Line impedance
— Propagation delay
— Reflections

> Single ended and differential data transmissions
— Terminations
— Eye diagrams
— Routing topologies

> Crosstalk
— Coupling mechanisms
— Near-End and Far-End crosstalk
— Crosstalk induced ISI

> IC modeling for SI simulations
— IBIS Modeling
— I\O buffer impedance analysis
— Package parasitics modeling

> Passive components & interconnect modeling
— S-parameters
— Touchstone modeling
— Capacitor modeling
— Via hole modeling
— 2D\3D Field solver extraction

> PCB Stack-up definition
— PCB material properties
— PCB build-up process
— Technology limitations
— IPC design recommendations

> Timing analysis
— Interface timing budget planning
— Interconnect propagation delays
— Jitter characterization

> Power Integrity of digital circuits
— Decoupling capacitor modeling
— Power nets/ plane parasitic modeling
— IR Drop Analysis
— Target Impedance definition for digital circuits
— AC domain analysis of decoupling networks
— Transient analysis of power line switching noise
— Power Distribution Network (PDN) Impedance analysis

> Interconnect modeling techniques

> Electromagnetic field solvers

> Signal & Power Integrity simulations tools
