Design Flow

This page contains improvements to the AWR Design Environment related to design flows.

Dramatically increase simulation throughput with parallel and remote simulation.

Parallel and remote simulation

Simultaneously run multiple simulations on the same computer or many computers with parallel local and remote simulation. Take advantage of parallel top-level simulations, sweeps, optimization analysis, and yield analysis.*

License requirements: Parallel simulation requires TOK-200 licenses. Remote simulation requires the same license feature set that the user has checked out on their machine. Please contact your local AWR sales representative if interested in learning more or demoing this feature.

Top Level Simulations

Run multiple top level simulations in parallel locally or remotely. Every measurement data source or EM Structure is a top level simulation and running them in parallel provides a significant performance increase.

The project will open and 4 intentionally slow top level simulations will simulate.

  1. Look at the project tree - there are four top level documents.
  2. Look at the simulation window - note that four simulations are scheduled and that the running simulation is running in a distributed MWO session (the simulation window prefixes the Name with DistSim).
  3. With proper licensing all SWRVAR_DIST sweep points will run in parallel, each in a separate distributed MWO session.
  4. Please contact your local AWR sales representitive if interested in learning more or demoing this feature.
  5. When done, cancel the simulations.

Sweeps

Run multiple sweeps in parallel locally or remotely. Some sweep run very efficiently in parallel (i.e. each frequency point of a power sweep, swept EM analysis, etc.).

The project will open and 4 intentionally slow sweeps will start.

  1. Look at the open schematic - there is a SWPVAR_DIST element to control distributed sweeps.
  2. Look at the simulation window - note that four simulations are scheduled and that the running simulation is running in a distributed MWO session (the simulation window prefixes the Name with DistSim).
  3. With proper licensing all SWRVAR_DIST sweep points will run in parallel, each in a separate distributed MWO session.
  4. Please contact your local AWR sales representitive if interested in learning more or demoing this feature.
  5. When done, cancel the simulations.

Optimization

Run optimization iterations in parallel locally or remotely. Advanced optimization algorithms (Parallel Advanced Genetic Algorithm and Parallel Particle Swarm) take advantage parallel iterations for increased performance.

The project will open and a parallel optimization will start.

  1. Look at the simulation window - note that four simulations are scheduled and that the running simulation is running in a distributed MWO session (the simulation window prefixes the Name with MWO:).
  2. With proper licensing many optimization iterations can run in parallel, each in a separate distributed MWO session.
  3. Please contact your local AWR sales representative if interested in learning more or demoing this feature.
  4. When done, close the task manager and cancel the simulations.

Yield

Run yield iterations in parallel locally or remotely. Yield analysis lends itself well to parallel iterations for increased performance.

Parallel yield analysis is not available in V14.0. If you have interest in this capability, please contact AWR Product Marketing

Jump-start matching network design using the Network Synthesis Wizard.

Matching Network Wizard Overview

The Network Synthesis Wizard allows the user to specify goals and components to generate matching network topologies in a matter of minutes. In this example an interstage matching network is designed to meet optimize power transfer between two non 50 Ohm networks.

Additional Network Synthesis Wizard examples can be found on the antenna and design flow pages.

The project will open to show the Matching Network Report Output Equations Page and simulate.

License requirements: Network Synthesis (SWS-100)

  1. Open the "Example" instance of the Network Synthesis Wizard and review the setup on each tab
    • Synthesis Definition - defines the "direction" of the matching network and frequency band(s) of interest.
    • Components - defines the available series and shunt components as well as first component and last component limitations.
    • Parameter Limits - defines the parameter limits, parameter rounding, component series, etc. for each component
      • Note that the L and C are limited to the E48 value table and that the TLINE values rounds to 0.1 Ohm.
    • DC & Bias Feed - defines the matching network DC path constraints and the bias injection network that the wizard should consider.
    • Goals - defines the Measurements and Goals for the synthesis. Double click on a Measurement or Goal to see the setup.
      • Note that the examples in this measurement uses the PA and Driver circuit impedances to calculate mismatch loss on both side of the synthesized matching network.
      • The goals is setup for 0 mismatch loss.
    • Search Options - defines advanced search options.
    • Results - shows the results from the Synthesis run and controls how many network and what additional data is sent back to Microwave Office

Synthesizing and sending results to Microwave Office

  1. Push the Synthesize button to start a new synthesis.
  2. Note that the candidate networks were synthesized in less than a minute for a simple problem like this!
  3. When the synthesis is complete click on the "Cost" column to sort the results by cost and note that the top 5 networks are selected for export to MWO.
  4. Click on the To MWO button to send the results to Microwave Office.
  5. Push the OK button on the "Overwrite Options" dialog.
  6. Push the Close button to close the Wizard.

Exploring results

  1. All of the generated networks have been sent to Microwave Office and placed in the <Synth_Results> User Folder in the Project Tree
  2. Click on the individual networks under the User Folder to see the results from the networks.
  3. Note that the Graph results update to show response with the selected network and the displayed schematic updates to show the selected networks
