Advanced Design System 2002 - What's New?

Models and Design Kits

Behavioral Modeling: Verification Model Extractor

Verification model extractor extracts system-level verification models from device-level circuit designs.

Faster Simulation for RF System Verification

The system-level models that are extracted by the verification model extractor offer simulation speed improvements up to 10 times faster than earlier ADS versions for designs with 10 or more active devices.

ADS Symbols for Sub-Networks

Any existing ADS schematic symbol can now be copied, modified if desired, and then used to represent any sub-network in the design.

ADS Design Kit Tool Set

A new interface and a documented methodology now exist for loading and unloading design kits in ADS.

Schematic Design Entry

Component Insertion with Hot Keys

Hot keys can now be created for any component. The menu command for each hot key is also added automatically to the Insert > Component menu in ADS.

Cadence Dynamic Link - Node Probing

Desired nets on the Cadence schematic can be selected interactively so that the corresponding data will be saved to the dataset.

Cadence Dynamic Link - Device Operating-Point Information

Detailed device operating-point information can be displayed directly on the Cadence schematic.

Configurable Netlist Exporter

The Configurable Netlist Exporter allows checking of ADS schematics against layouts built in third-party tools including Cadence Dracula and Assura and Mentor Calibre.

Analysis Setup

DesignGuides

New DesignGuides support filter design and 5-GHz wireless LAN design.

The wireless LAN DesignGuide is included in the E8874A 5-GHz Wireless LAN Design Library.

Filter DesignGuide

The Filter DesignGuide synthesizes lumped-element filters for RF/microwave circuit design using a wizard-like user interface for design specification, interactive response tuning, tolerance/sensitivity analysis and auto-simulation.

Wireless Design Libraries

cdma 2000 Design Library

Enhancements to the cdma2000 DesignLibrary include code domain power and Rho measurements, new BS, BER, and MS projects, and an upgraded signal source project.

Simulation

ADS 2002 improves simulation performance and shortens product development time by increasing simulation speed, more efficiently utilizing memory and providing new analysis capabilities for the most challenging and strongly nonlinear designs.

Enhancements include advances in the DC convergence algorithm, advanced memory utilization for harmonic balance simulations, faster transient (HF-SPICE) simulation, and algorithm advances to the Krylov HB pre-conditioners.

ADS 2002 also features a new Shur-Complement Krylov HB pre-conditioner for simulating large strongly non-linear designs and a Krylov HB capability for circuit envelope and oscillator simulations.

EM/Circuit Co-Simulation with Layout Components

Co-simulation with layout components brings physical electro-magnetic (EM) effects into the schematic environment. Co-simulation with Layout components 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 EM effects.

Speed, Capacity, and Convergence

Improved DC convergence algorithms for parallel inductors (loops) and series capacitors now overcome problems with extremely large and small component values in a circuit.

Improvements in transient simulation (HF-SPICE) have increased transient analysis speed by ten per cent.

Transient Noise Analysis

Transient noise analysis in the time domain is now available for wireline applications. This makes it possible to simulate jitter in oscillators and clock data recovery circuits.

Faster BER Simulations

Ptolemy Simulation and Models

Enhancements in Ptolemy data-flow simulations include speed and run-time-memory improvements. BER simulations now support LSF HDL Co-simulation with Cadence's NC-Sim.

NC-Sim HDL Co-Simulation

Data Display

A new Trace Display Mode - called Draft mode - is available for the faster display of large amounts of data (>20 k data points).

Physical Design

ADS 2002 Layout - New Features and Improvements

New features in ADS 2002 layout include a user-defined ruler, the ability to choose 45 degrees as the lock angle, a marker showing the text origin, an easy palette for inserting and editing meander transmission line components/traces/paths, automatic updating of sub-networks, and import of hierarchical MDS layouts.

Meander Lines Easy Palette

Inserting and editing meander transmission line components/traces/path within given space constraints is now a one-step process from the easy set-up palette.

Faster Redraw Speed

Depending on the size of the layout, 2x to 10x improvements in redraw speed can be expected. These improvements are due to new options allowing control over the depth of plotting in hierarchical designs, minimum object sizes, and display box sizes.

New and Improved Boolean Code

A new Boolean operations engine offers additional and enhanced Boolean operations in layout.

New Layout Ruler

A user-defined layout ruler makes it easier to check layout dimensions quickly.

Check for Missing Wires

Additions to the menu command Check Representation make it possible to check for mismatches in nodes between the layout and the schematic and to detect wires in the schematic that are missing from the layout.

Design Verification

Measured Signals Used as a Simulation Source

The Agilent 89600 Vector Signal Analyzer (VSA) software offers a new measurement-based signal source element in ADS to bring IQ data from the Agilent 89600 VSA, E4406A VSA, or E4440 PSA into ADS for use as a simulation source.

This new signal source element allows analysis and verification to transition from the test bench back into ADS to perform connected-analysis in ADS.

New and Improved Instrument Links

Design Documentation, Web-Based Training

Electronic Lab Notebook

The ADS Electronic Notebook creates HTML documents for project designs and results. This saves time documenting designs and makes it easy to share design information using Microsoft Internet Explorer (versions 4.0 and above).

Web-Based Product Training

Web-based product training is available in ADS Fundamentals, ADS Momentum, ADS Communications System Designer, and WCDMA/3GPP Communication Systems Design. Advanced Topics in Circuit Design goes online in February 2002.
