Advanced Design System (ADS) 2002 from Agilent Technologies is an electronic design automation (EDA) software that features advances in simulation technology and usability for engineers creating radio frequency (RF) designs. ADS 2002 is tailored for system and circuit design engineers developing all types of RF designs from discrete RF/microwave modules to integrated monolithic microwave integrated circuits (MMIC) for communications and aerospace/defense applications.

Advances in ADS 2002 include:

• Co-simulation with layout components: Bring physical electro-magnetic (EM) effects into the schematic environment. The co-simulation feature breaks down the barriers between electrical and physical analysis domains. This enables designers to incorporate layout artwork in schematic environments for concurrent analysis of circuit performance along with critical physical (electro-magnetic) effects.

• A verification model extractor: Extracts system-level verification models from device-level circuit designs. The extracted models offer simulation speed improvements up to 10 times faster than earlier ADS versions for designs with 10 or more active devices.

• New simulation technologies that provide greater levels of simulation performance: Enhancements include advances in the DC convergence algorithm, advanced memory utilization for harmonic balance simulations, faster transient (HF-SPICE) simulation in the only SPICE simulator created for microwave circuit design, and algorithm advances to the Krylov HB pre-conditioners. ADS 2002 features a new Shur-Complement Krylov HB pre-conditioner and a Krylov HB capability for circuit envelope and oscillator simulations.

These three new capabilities are being offered for the first time in commercial EDA software. The software also offers a new filter DesignGuide that synthesizes lumped-element filters for RF/microwave circuit design using a wizard-like user interface for design specification, tolerance/sensitivity analysis, auto-simulation and interactive response tuning.

ADS supports the following operating systems: SolarisTM 7 and 8 Operating Environment (Solaris OE); Microsoft Windows 98/NT 4.0/2000/; HP-UX 10.20 and 11.0; and IBM AIX 4.3.
