10.2. Removing Resource Sharing Folding

With DSP Builder v14.0 you could use resource sharing folding, which is now removed in v14.1 or later. When you open pre v14.1 designs in v14.1 or later, you must remove resource sharing folding, which you originally selected on the ChannelIn block:


  1. Open the design in v14.1 or later.
  2. Replace ChannelIn and ChannelOut blocks with new ChannelIn and ChannelOut blocks.
  3. Change any part of your design that uses TDM vectors.
  4. Change any aspects of your design that uses a sample delays rather than clock delays.
    Note: If you do not remove resource sharing folding, and you simulate your design you see a MATLAB system error.
