The latest version of Ansoft Designer offers expanded Solver on Demand capability and new design verification technology to speed the design process of RF systems and RF/analogue ICs and to increase the accuracy of signal-integrity studies.

"Ansoft Designer allows engineers to capture high-frequency parasitic behaviour directly in their circuit simulation and apply that knowledge toward design optimisation and verification", said Dr Rich Hall, Director of Ansoft Designer R and D.

"By extending the Solver on Demand technology to include HFSS engineers can perform parametric design optimisation with gigahertz-accurate full-wave extraction".

By including HFSS, Ansoft's 3D full-wave electromagnetic-field simulation software, into Ansoft Designer's Solver on Demand capability, engineers gain maximum flexibility in characterising RF components.

Users can easily implement electrical models ranging from Ansoft Designer's planar EM or approximated equivalent circuit models to 3D full-wave using HFSS through a single key click.

The ability to balance the optimum level of accuracy versus required simulation speed provides a great benefit to engineering productivity.

For designs with large transistor counts and/or high spectral content, Ansoft Designer v3 also supports HFSS cosimulation with Nexxim, Ansoft's high-capacity, transient and harmonic balance, circuit-simulation software.

The new design verification features include user-defined design rule checking (DRC) to address the design for manufacturing (DFM) requirements of high-performance RF, IC and SI applications.

Individual designers and CAD/EDA support professionals can now implement design-verification scripts to track manufacturing constraints and flag potential problems before tape-out.

Ansoft Designer v3 is available on PCs running Windows 2000, XP, and Server 2003 Standard Edition.
