Release Highlights - Genesys 2008.01
Completely New
Momentum GX Momentum GX now supports producing Far Field patterns and Antenna characteristics calculation (see two examples demonstrating this in MomentumGX/Antennas).
A new option to automatically reconnect and center layout before running allows optimizations and sweeps to be run while changing line lengths and widths (see the example MomentumGX\MomentumGX evaluations.wsx).
Mesh reduction can be defined in Momentum GX properties.
Momentum GX:
Search Path for Libraries In this release, you can now select a set of libraries that will be automatically searched if an object has no library reference name. This applies to symbols and models as well as substrates and all other objects that can come from libraries.
The Library Manager has been enhanced to support checking libraries on/off for the search set. It also enables you to order libraries so they are searched in a specific order.
For example, if you have a library "MyModels" that you have been using for your models, you might just want to add it to the Designs search path and then you can refer to your models by short-name rather than short-name@MyModels.
The Equation Search Path is used with the M Language function call support - which can select functions from libraries using the search path.
Math Language Equations Genesys now supports a second equation language. The language selection is done in the equation window by clicking the G button and picking Genesys Language or Math Language.
The G language is our traditional Genesys Equation language.
We do not have much documentation on the new Math equation language but it helps to be familiar with .M-file programming. The Math equation language does not have the concept of sweeps, dependent, and independent variables. The Math language supports basic network TCP/IP communications for controlling and reading instruments.
Interactive Annotation Widgets Slider that can be placed on a schematic, live report or graph that allows for tuning of parameters (see example Tutorial\Slider Controls.wsx).
Button that can be placed on a schematic, live report or graph to run a script (see example Tutorial\Command Btn Example.wsx).
Changes
Drag and Drop Support for drag and drop from workspace tree of S-Data datasets and designs into a schematic to be used as sub-circuits
Added "Preferred Symbol" selection for design
Momentum GX Added "convert circular vias to squares" feature. Allows for reduction in memory usage
Support layout element pad rotation to arbitrary angle
Support of vias, connected box metal covers
Support vias through air layers
Support "angle resolution" for pads and rounded transmission lines
Spectrasys Improved simulation speed by a factor of 2 or more
New Frequency dependent attenuator model
New Linear voltage and power gain only block models
New non linear voltage and power based high and low order models. These models support reverse intermod generation
Added 12 new equation based measurements which use only the user entered stage information and are the same as traditional calculations used in spreadsheets
Added self mixing capability to the basic mixer
Added new IPSAT and OPSAT measurements
Added ability to only store power, voltage, or both groups of measurements in path datasets
Added ability for the user to select signals within a given range of a peak signal for intermod generation
Added system simulation information to simulation log
Graph Can directly tell graph a measurement to use as the independent (x-axis)
Allow drawing in stages. Will speed up operations that redraw multiple times (optimizations, sweeps, re-size, zooming ...). Option to turn this off in global options
Data reduction when number of data points is large (speed up for drawing, tooltips and overall response)
Optimization Added Delta selection and set to 1e-5 for Optimizations to improve gradient optimization of linear circuits
Approximately 30% speedup with frequency dependent linear circuits
Linear Added new symbols for S data models
Added 1 and 2 port S data parts
Added subcircuit part
Added new S data and subcircuit parts to linear toolbar
General Directly edit model name and symbol name on a Part Parameters properties page.
Major changes to the way connectors (wires) connect after a drag to ensure connector points are consistent with standard schematic practice
Equations on same level of hierarchy can now always see each other's variables
Toolbar button on main toolbar to allow hide/show dockers (simulation log, workspace tree...)
Mouse wheel now scrolls for schematic, live report and layout. Ctrl+Mousewheel zooms. Settable in Tools / Options
Improved Add New Variable to dataset (can now dbl-click empty area to add a var, custom dlg title support)
User-specified Frequency Units are now used when creating new F variable
Support copy/paste of a graph to metafile from Live Report
Ability to browse for VA models from Part Parameter, Change Model
Rectangular selection tool no longer includes sch part text in its page bounds test (only symbol body needs to be surrounded to include part in selection)
Reassigned hotkey 'D' in schematic to Nonlinear Diode
Model Improvements CCCoupler1Model for DC
MCurve
Sign of PTF parameter of nonlinear BJT models
Noise for MOSFET
Changed minimum value of Rd from 0.01 to 0.001 Ohms, to support power MOSFETs
Fixed nonzero bulk resistances error for transient and HB simulations
Implemented noise analysis
Fixed VCVS model (disconnected -In and -Out)
Tables Support user-selectable display units
Now save auto-sized column widths when the table window is closed
Harbec Added new dataset variable IPORT - port injected currents
Implemented new function calculating Large S parameters largeS, largeSmix, largeSconv
Layout Support any port location in footprint pad area, including edges
