New features and changes introduced in this version are:
The SimRF Outport block now supports output of real-passband signals from the SimRF™ environment. See the Reduce Computations by Using RF Simulation Techniques example in the Getting Started documentation for a comparison SimRF and Simulink techniques for modeling real passband signals.
To run models with SimRF Equivalent Baseband library blocks, you no longer need to install DSP System Toolbox™ software. In this version, you must install DSP System Toolbox software only if you want to use:
SimRF Idealized Baseband library blocks.
DSP System Toolbox features, such as frames and DSP System Toolbox library blocks.
To run models with S-Parameters blocks, SimRF software no longer generates support files. In this version, SimRF models require compilation only when they contain an Amplifier or Mixer block.
Models from previous versions that contain Amplifier or Mixer do not run in this version unless you recompile them. To run this type of model in the new version, perform one of the following procedures.
Copy your model, rename it, and run the renamed model in the new version. This action causes SimRF to generate new support files with different file names, leaving the original model and support files intact. This procedure guarantees that the original model continues to run in the old version.
Run the model in the new version, and follow the instructions on the error message to delete the old support files. Next, run the model again to generate new support files. The recompiled model does not run in previous versions.
The S-Parameters block now displays rational fitting results alongside data in the Visualization pane. You can use this feature to validate simulation of S-parameter data in SimRF software.
The SimRF Parameters block now supports noise temperature modeling from a single parameter. Set the Temperature parameter to model a global noise temperature for each Amplifier and Mixer block in the SimRF environment.
The Noise block now supports noise modeling on a subset of carrier frequencies. Set the Carrier frequencies parameter to a vector of frequencies to model noise on only those carriers.
For R2011b, error and warning messages identifiers have changed in SimRF software.
If you have scripts or functions that use message identifiers that changed, you must update the code to use the new identifiers. Typically, message identifiers are used to turn off specific warning messages.
For example, the SimRF:InvalidString identifier has changed to simrf:simrf_restring:InvalidString. If your code checks for SimRF:InvalidString, you must update it to check for simrf:simrf_restring:InvalidString instead.
To determine the identifier for a warning, run the following command just after you see the warning:
[MSG,MSGID] = lastwarn;
This command saves the message identifier to the variable MSGID.
Note Warning messages indicate a potential issue with your code. While you can turn off a warning, a suggested alternative is to change your code so it runs warning-free. |
