What's new in GENESYS 2003.03

Genesys 2003.03 also includes all features found in GENESYS 2002.09 and earlier versions. See our Comparison Table of Recent Versions for an easy reference.

The latest release of Eagleware's GENESYS microwave and RF design suite, version 2003.03, introduces the High-Accuracy RLC Library from Modelithics, a set of high-accuracy passive component models, an internationalized version, new system and circuit models, improved schematic wiring, one-step graph/table creation, as well as numerous enhancements improving your ease of use.

MODELITHICS SUBSTRATE DEPENDENT LIBRARIES

Eagleware, in conjunction with Modelithics of Tampa, FL, now offers accurate substrate-dependant model libraries for a wide variety of components. Unlike traditional component libraries that offer simple models, the RLC libraries include sophisticated models that account for substrate effects. Derived from careful measurements, you will see how the self-resonance and other parasitic effects vary with dielectric constant and material thickness. These models will help you select the right component for the frequency range and substrate that you are using, saving you time and design turns.

INTERNATIONALIZATION

Designers can now label parts, write equations and notes, and name files and workspace objects in their native languages. This may be Japanese, Korean, Chinese, Russian, or any language compatible with Microsoft Windows. Designers use their local language keyboards, and key layouts may be easily changed to support multilingual workspaces. Since GENESYS is a Unicode application, files can be exchanged worldwide with full compatibility.

To make GENESYS even more accessible, Eagleware has also localized its software suite by translating menu commands, dialog boxes, error messages, and tool tips into a growing list of languages, currently including Japanese, Korean, and Chinese (both traditional for Taiwan and simplified for PRC). With internationalization and localization, the entire process of architecture design, synthesis, linear, nonlinear and EM simulation, physical design, test, and documentation can be accomplished in the user's first language.

Internationalization and localization improves communications with colleagues and customers, reduces errors, and speeds the design process from start to finish. With today's announcement, Eagleware becomes the first company in the RF and microwave industry to make its software accessible internationally.

INTERMOD TABLE MIXER

The new Intermod mixer table in SPECTRASYS gives you additional capabilities not available in any other simulation product. Some of these capabilities include the ability: 1) to identify every spectral component at the mixer output including the identification of the LO spectrum used to create the output spectrum, 2) to easily define the Intermod table in the equation block, and 3) to define in the equation block additional spectral components getting into the mixer input.

These capabilities put the power back in the hands of designers so that they can make the best-informed decision about the mixer and subsequent architecture in the shortest amount of time. For instance, the immediate identification capability informs the designer of the most detrimental mixer products allowing architectural changes before committing to hardware. Furthermore, defining the Intermod table in the equation block gives the designer the ability to make each and every entry in the table a function frequency, power level, or any other parameter that can be defined by an equation or parameter.

NONLINEAR SWITCHES

The nonlinear input parameters of 1 dB compression (P1dB), saturation power (PSAT), third order intercept (IP3), and second order intercept (IP2) have been added to the linear switches (SPST through SP20T) to create nonlinear switches. You will be able to see and identify all second and third order distortion products created by these switches.

FREQUENCY DIVIDER

This new model divides any spectrum arriving at its input by the division ratio specified by the user. Subharmonics can also be specified in a harmonic table contained in the model. As with any other SPECTRASYS element, spectrum identification can be used with the divider to determine the source of all divided spectrums at the frequency divider output.

NONLINEAR FIXED and VARIABLE ATTENUATORS

The nonlinear input parameters of 1 dB compression (P1dB), saturation power (PSAT), third order intercept (IP3), and second order intercept (IP2) have been added to the fixed and variable attenuators to create non-linear attenuators. Now the user will be able to see and identify all second and third order distortion products created by these attenuators. 

SCHEMATIC PART AutoWire

Connecting parts in the schematic editor has never been easier. You can now hover the arrow cursor over a part terminal to enter the new AutoWire mode. When the cursor changes, you can now press and hold the left mouse button to drag a wire from that terminal, without having to click on the "Draw a 90 degree connection line (Wire)" toolbar button first. By default, an orthogonal (90 degree) wire will be placed, but holding the SHIFT key down, while hovering over the terminal, will place an angled wire instead. AutoWire does not interfere with the SPACE key command, which drops a new part (whatever was placed last), i.e., the next time you press SPACE you will drop a new part, not a new wire.

NEW GRAPH / TABLE MENU COMMAND

The schematic editor has a new submenu on the right button menu. When you right-click on a port or node, you can use the new submenu to easily add a new graph or table to your workspace. Frequently used measurements, based on the simulations available, will appear in the menu.

"Relevant" measurements, like the S-Parameters of the clicked-on port, are simply the S-Parameter measurements that are most likely to be of interest (in regards to the selected port). You can double-click the graph and choose to hide any traces that you prefer not to display.

ASYMMETRIC-COUPLED MICROSTRIP LINES

This new linear schematic element (MCN4A) models the response of two parallel-coupled microstrip lines of different widths. The associated layout can be automatically generated. The element is found on the microstrip toolbar. The response is accurate over the same range of parameter values as the symmetrical coupled lines element (MCP).

NEW USER CUSTOMIZATION

You may now customize GENESYS using three new files.

1. UserButtons.lst A text file that supports customization of the drop down buttons for selecting models.
2. UserModels.mod  A text file method of creating models. You would normally use a workspace with model definitions; this file is provided to support older customization schemes.
3. UserDesignators.dat  A text file method of overriding the GENESYS default designators (those part names provided when a part is first placed in a schematic). In prior versions, this was done by editing Designators.dat, the Eagleware provided designators file.

GENESYS 2003.03 now supports multiple equation blocks. You can define more than one equation block by adding equations to the workspace. Each equation block can have its own name. All equation blocks are parsed for the workspace. The new version also supports multiple note pads. Add a new note pad the same way you add a new GENESYS object. The note pad can be named and can be made to come up in any part of the screen when the workspace is saved. This is a handy way to keep separate notes on various pieces of your workspace.

FREQUENCY-DEPENDENT NOISE SOURCES

GENESYS 2003.03 adds frequency-dependent noise sources (voltage and current). Noise source amplitudes and frequencies can be set from the equation block. Noise sources are selected when editing a schematic under the source pull-down as source:noise voltage and source:noise current.

NEW HARBEC OSCILLATOR ANALYSIS

With GENESYS 2003.03, you may now use our HARBEC (Harmonic Balance Analysis) engine to analyze oscillators. This analysis includes nonlinear effects of active components to produce a more accurate estimate of the oscillation frequency as well as a complete spectral analysis of the oscillator circuit. HARBEC works in a fully closed loop with oscillators. Below is a picture of a GENESYS screen with oscillator analysis.
