BELLEVUE, WA – May 22, 2009 – Physware, Inc., a provider of high-speed and high capacity 3D electro-magnetic solutions for Signal Integrity (SI), Power Integrity (PI), Electromagnetic Interference (EMI) Integrity and Simultaneous Noise Integrity (SNI), today announced that PhysWAVE, Physware’s flagship 3D fullwave solution, has been optimized to assist design of MIMO Antennas for RF Front Ends and Wireless ASICS. 

Tackling SI-PI-EMI-SNI (Simultaneous Noise Integrity) issues involving RDL and GDS layers, complete packages, sections of board, and embedded passive and decoupling capacitors is non-trivial. PhysWAVE makes this easier for the designer through flexibility, scaling, accuracy, and efficiency of underlying 3D accelerated boundary element technology. This technology also provides sufficient flexibility to model integrated antennas within the same complex system environments. Users can therefore use one tool environment to examine both undesired (EMI / EMC) and desired (antenna patterns) crosstalk, impedance mismatches, and radiation. Importantly, the antenna patterns are not idealized but are those produced in the presence of the integrated system. Therefore effects such as multi-antenna crosstalk, interferences from signal lines, power noise coupling, non-ideal and finite grounds, and non-planarities are sufficiently accounted for.

“Wireless ASICs, RF Frontends for data and voice transmission, GPS subsystems, and RFID tags and systems require integrated antenna sub-systems. These antennas need to provide multiple transmit-receive, multi-input multi-output, and possibly frequency-reuse functionality. The antennas need to function in the presence of non-ideal environments and a background of EMI and crosstalk emanating from the system. In addition, antennas may couple back into elements of GDS and RDL layers, packages, and sections of the board. While several stand-alone antenna simulation tools exist, what is required, for an effective solution, is a single-suite solution that allows for modeling of antennas in the same framework as SI-PI-EMI-SNI simulation for chip-through-system. PhysWAVE, through its flexibility and scalability, makes this possible today”, said Dr. Junho Cha, Applications Specialist, Physware, Inc.
