AWR Design Environment™

Version 2009 - What’s New?

© 2009 AWR Corporation

What’s New in Microwave Office® and Analog Office®?

• Simulation:– APLAC® multi-rate harmonic balance

(MRHB™)– Constant output power simulation– Load-pull analysis– EM extraction enhancements

• Models:– X-models– Behavioral model support

• Mesuro's active load-pull system• User-Experience:

– Layout enhancements– Measurements– Customizable project tree

• And more– Filter Synthesis– Optimization– Licensing


Simulation: Multi-Rate Harmonic Balance (APLAC only)

• Each circuit element / section solves only the necessary tones and harmonics

• Useful for any design with up/down conversion or designs where some circuit elements need many harmonics and others do not.

frequency sweep etc.– Schematic – hierarchy import/export, element display visibility etc.– Simulation – pick project frequencies from a datafile

• New help page to explain script functionality– https://awrcorp.com/scripting/doku.php?id=landing:start


User Interface: Discrete Model Blocks


User Interface: User Folders

• New node in project tree• Any data item can be stored in a folder• Folders can have multiple levels of hierarchy


User Interface: Project Tree

• When data items (schematics, graphs, etc.) are duplicated…– They are automatically ready to be renamed

• When a measurement is duplicated…– The add/modify measurement dialog automatically opens

• Expand / collapse state of the project is now remembered


User Interface: Startup Dialog


Filter Synthesis: iFilter™

Filter Wizard– Optional module

• iFilter – Distributed– Coming soon…– Optional module


Optimization: Good News!

Optimization continues on even when an error condition is encountered!


Licensing

• All physical verification interface licenses now include ICED and Calibre

• Multi-core APLAC harmonic balance licenses are also now included with all nonlinear simulator licenses

• An AXIEM™ license is now only checked out for simulation (i.e., when AXIEM is in use). This also allows for manual return by the user too.
