Signal Integrity
Bandwidth growth with smaller form factors at speeds of 100G today and 400G tomorrow is necessary to support 5G and IOT technologies. The faster signal rise and fall times mean high frequency signal components!. CROSSTALKs, both near-end crosstalk (NEXT) and far-end crosstalk (FEXT) become more severe; LOSSES: skin effect, dielectric losses, rough surface scatterings, and radiation losses, become significant; and NONIDEAL RETURN PATHS start to show up. These effects will degrade your system's signal integrity...
Power Integrity
Example: small lightweight IOT devices must be extremely power efficient. To prevent product malfunction or failure caused by voltage loss on critical supply nets, it is important to analyze power intergrity during layout. Excessive current density and unpredictable circuit behaviors must be paid attentions....
Developed by my colleague, Dr. Cosmin Iorga, a novel method for power integrity analysis and power delivery network (PDN) models extraction, in FPGA systems by configuring the FPGA to function as a Vector Network Analyzer (VNA) test instrument for its own power delivery network, please visit the website: piscanner.com
Electromagnetic Compatibility
Example: EMI electromagnetic interferrence, RF modules/blocks need shieldings and via stiching etc.! As such, consideration for, must become part of the IOT product design and analysis methodology. Common sources of EMI are Components' parasitic L&C, PCBs' post-layout parasitic L&C, Systems and Components' Instability, and Non-harmonic rings. Both common-mode EMI and differential-EMI must be reduced in order to meet the stringent standards such as FCC, CISPR etc.; PCB layout parasitic must be accurately extracted via 3D EM solver/modeler, and lowered; EMI noise filters can be properly used....
