Asynchronous EM Simulation	Simulation State Management (SSM)
With AWR 2011’s asynchronous EM simulation support, users don’t need to wait for EM analysis to finish or EM results to be reintegrated into their design. With asynchronous EM, AWR users keep working, while their EM analyses run behind the scenes, transparently on multiple CPUs on the same computer or with distributed jobs on networks or clusters (coming soon). Job queuing allows ‘what if’ scenarios to be scheduled immediately and run in parallel.	AWR 2011 incorporates a new, comprehensive approach to managing simulation results within the design environment framework for both synchronous and asynchronous simulation data. SSM allows users to easily track, manage and visualize/apply simulation results for the current and/or any previous simulation. The SSM utility also supports a per-simulation approach to data sets that allows for a more granular control of such results. All simulation results can be stored in data sets and managed by SSM, allowing the user to control the amount of simulation history retained as the design progresses.

Group Design	EM Yield, Sweeps & Optimization
AWR 2011 introduces new capabilities to improve user productivity for group design/design teams such as the ability to manage project data and resolve conflicts as sub-designs are combined into a higher-level, overall project design. Schematics, layouts, EM, analysis, and measurements are all importable from existing designs. Multiple sets of global and output equations can be handled readily as well. Conflicts are identified upon import and can be addressed immediately, block-by-block, as the design or sub-design is imported, and ensures that blocks stay self-synchronized as the design complexity grows from existing or as-designed components.	With AWR 2011, EM yield, sweeps, optimization and DFM are a well-integrated and very real component of design. Capitalizing on the parametric and schematic type of EM shapes, arbitrary shapes and geometries, as well as user-defined layers can readily take into account manufacturing-related effects, like mask alignment and etch tolerance. Overlay these with SSM capabilities, users are now able to track each variant, such as looking for corner cases or actually sweeping manufacturing-related parameters or even monitoring overall performance of circuit simulations in linear, HB, or time-domain circuit simulations.

Envelope Analysis	Radar Design Library
AWR 2011 now offers expanded co-simulation capabilities between Microwave Office & Visual System Simulator with the addition of a new envelope simulator. Envelope simulation enables designers to simulate circuit level time variant phenomena such as memory effect and sophisticated digital predistortion (DPD) configurations that rely on dynamic bias or envelope tracking methodologies.	AWR 2011 now includes a radar design library. The library allows detailed behavioral modeling of the RF and signal processing of a radar systems, together with 3D antenna patterns derived from synthesis or measurement. Links to Matlab and LabVIEW allow custom signal processing algorithms.
