Simulator makes sense of RF signal integrity
Nexxim is a novel product targeting the next generation of analogue/mixed-signal applications, including high-performance RFCMOS, GaAs/SiGe RF ICs and gigabit computer and communication backplanes.
Design software gains solvers on demand
Ansoft Designer v2.0 expands the company's Solver on Demand technology to include Nexxim, for RF/mixed-signal circuit simulation, and Q3D Extractor, for 3D quasi-static parasitic extraction.
This eliminates prototype iterations that require expensive test equipment and multiple spins that delay time to market.
Modern electronic products use gigabit-speed serial links to move large quantities of digital data across today's telecommunication, high-definition video, gaming and data storage systems.
Ansoft's electromagnetic modelling and advanced circuit simulation are essential for designing these data links.

Simulator gains Murata library
Users of Ansoft's Nexxim can now use a new device library based on Murata's discrete capacitor/coil inductor products.
Serial link standards, such as PCI Express, Serial ATA, Gigabit Ethernet and HDMI have very stringent accuracy requirements, allowing only one bit in billions to be in error.
Previous methods for simulating link performance required long simulation times to capture these low bit error rates (BERs).
The new technologies give engineers methods to rapidly predict system-level performance with eye diagram plots and BER curves.
Nexxim V4 features VerifEye, a new methodology for eye analysis of serial links using statistical methods that maintain accuracy while offering major reductions in run time compared to conventional transient methods.
These statistical transient analysis tools represent the most practicable means to test for the low bit error rates needed by today's multiGb/s channel designers.
Nexxim V4 also features QuickEye, a fast eye diagram analysis method that allows input of very long, user-defined bit streams.
This analysis allows engineers to identify specific bit sequences that cause bit errors.
Nexxim V4 features new mixed system-level behavioural simulation with transistor-level transient simulation.
This hybrid integration enables designers to simulate a complete system consisting of various levels of abstraction much more quickly than in simulators that operate at only the transistor level.
Ansoft Designer V4 features a new "push excitation" feature and enhanced dynamic links to Nexxim and to Ansoft'sHFSS, SIwave and Q3D Extractor electromagnetic field simulation tools.
These products combine to allow engineers to accurately predict signal integrity effects and EMI/EMC performance of advanced electronic systems, including gigabit communication channels, multifunction high-speed wireless systems and sophisticated microwave systems.
