Microwave Office 2008 offers increased flexibility

With Ver 2008 of the Microwave Office design environment, Applied Wave Research Inc. (AWR) has made significant changes to the user interface to increase its flexibility for the user. The new version also includes APLAC harmonic balance (HB) analysis software as an alternative nonlinear HB engine within the Microwave Office high-frequency design suite. The company reported that overall, hundreds of improvements have been made throughout the design environment.

In ver 2008, the appearance of the overall interface can now be switched back and forth to appear much like Microsoft Office 2000 or 2003. AWR explained that it made these changes for users to customize easily the design environment to suit personal preferences, with the goal of streamlining various design tasks to save time and optimizing screen space available for design.

The AWR-APLAC foundry-approved RF simulation capability was previously available only as an option in the AWR design environment, but now comes as a standard HB engine in ver 2008 for customers who license the HB capabilities of the Microwave Office design environment. The APLAC engine is targeted at designers of complex, extremely nonlinear circuits and is based on a proprietary implementation of HB analysis that complements the frequency-domain simulation capabilities of Microwave Office. It has been fine-tuned based on more than 15 years of experience in RFIC design at Nokia and other device manufacturers, and AWR noted that it has been used in the design of more than 30 percent of all mobile phone RFICs.

Advanced designs
In addition to the user interface and APLAC enhancements, Microwave Office software now incorporates ICED IC verification software along with its support for Mentor Graphics Calibre. Since the last major release, AWR has added advanced process design kits for TriQuint Semiconductor, WIN Semiconductor Corp., and United Monolithic Semiconductors, and more are planned for the coming months.

System optimization
Ver 2008 also features enhancements to AWR's Visual System Simulator (VSS) software, which was integrated into the AWR design environment several years ago. This software suite aims to assist the end-to-end design and optimization of communications systems by enabling the impact of real-world signal impairments and other factors to be evaluated early in the design cycle when they can be addressed most effectively. VSS provides the tools necessary to optimize each of the components in a system architecture from the behavioral through component levels (in relation to Microwave Office software or AWR's Analog Office software), and then using actual device measurements to validate the final design.

VSS also includes an enhanced RF budget analysis tool, which enables the user to make traditional RF-cascaded measurements along a communication link that now uses a circuit solver and expands the range of supported topologies. Cosimulation with Microwave Office, including the APLAC HB engine, is also now enabled.
