Norcross, G.A.Eagleware-Elanix Corporation announced
GENESYS 2005, a major new release of its RF and microwave design suite. The new version includes WhatIF (a new frequency planning tool), CAYENNE (a new time domain simulator), and two new synthesis modules, designated AMPLIFIER and MIXER, as well as enhancements to the linear, nonlinear, and system architecture simulators, new models, and a revamped user interface.
The new version includes a frequency planning tool that uses a new simulation technique that analyzes spurious performance of intermediate frequencies (IFs). Spur-free regions are identified, including multiple frequency band conversions to a common IF. Users see performance tradeoffs between IFs and can identify all spurious offenders, giving them control over mixer requirements and specifications. Simulation speed is fast since conventional sweep analysis has been eliminated.
CAYENNE is a SPICE-like time domain simulator. In addition to the normal analysis capabilities available in other time domain simulators, it incorporates direct use of S-parameter data. In addition to full-frequency convolution, its faster hybrid frequency/time mode creates models that are accurate at a specific high frequency and are approximate at other frequencies. It also allows trade-off of accuracy versus simulation time; co-simulation with electromagnetic simulator, including lumped elements; compatibility with all GENESYS linear, nonlinear, Verilog-A, and system elements; and it accepts data written by SystemVue system simulator to allow RF/Microwave transient analysis with real baseband time domain input.
The new mixer synthesis module allows the user to design and analyze mixer configurations using a variety of topologies as starting points. The 11 topologies of the initial release range from simple passive configurations to complex active models. For each configuration, supporting information provides insights into the theory of operation, applicable frequency range, and performance tradeoffs.
The new amplifier synthesis module facilitates the design of linear low-noise RF amplifiers. Requirements can be automatically transferred from system-level behavioral models, and simulation results can be exported to system-level simulation to check results. Transistor and FET implementations are supported in both single and multiple stage configurations.
User interface enhancements in the new version include: datasets that provide a persistent view of simulation results and permit easy comparisons among simulation runs; enhancements to the equations capabilities to include structured programming constructs such as WHILE loops and multi-line if-then-else statements; and extended scripting capabilities to support all design elements.
Other enhancements to the suite include:
- Filter synthesis now supports generation of differential filters
- Oscillator synthesis now supports closed-loop time domain analysis
- SPECTRASYS spectral domain simulation has been enhanced to include support for voltage analysis and measurements, arbitrary port/model impedance, phase noise, and hierarchical models
- New Motorola LDMOS models, Taconic Substrate Library, and new ideal circuit components
The software will be available in Q3 2005, and pricing starts at $5,000. Click here for more information.
