New technology creates 'best practice' for signal and power integrity analysis

With Ansoft Designer 6.0's new Solver on Demand technology from ANSYS, electronic design engineers can quickly and accurately analyse signal integrity, power integrity and emi problems from a single schematic and layout-based environment.

Ansoft Designer 6.0 is said to enable high speed electronics and rf/microwave designers to access field and circuit simulation tools while designing electronic packages and pcbs early in the design cycle before manufacturing costs are incurred. Solver on Demand technology integrates HFSS 3d electromagnetic field simulation software from ANSYS and HSPICE, an integrated circuit simulation tool from Synopsys within the Ansoft Designer 6.0 design platform. The resulting benchmark design flow offers the ability to predict how high frequency electromagnetic components affect the integrated circuits. The design platform brings the power of HFSS 3d modelling to the layout and allows it to be combined with encrypted HSPICE models. Addressing the challenges that electromagnetic field simulation raises, HFSS has been built directly into Ansoft Designer 6.0. Models of rfic layout, ic packages and pcbs from Cadence Design Systems, Mentor Graphics and Zuken can be imported directly to Ansoft Designer and solved in HFSS without any further setup. The package layout can be parameterised to compute tuning and sensitivity to understand impedance variations due to process. Ansoft Designer 6.0 is said to provide a powerful user interface to HSPICE with direct links to HFSS and access to the ANSYS QuickEye and VerifEye convolution and statistical eye analysis as well as IBIS-AMI technology.
