Critical Issue
Description
DSP Builder designs that contain Simulink algebraic loops may produce error messages.
Resolution
To work around this problem, add a SampleDelay block
on each input to the ChannelOut block and press play.
DSP Builder spreads around and balances latencies and delays. During simulation, you now have SampleDelay blocks across your feedback paths and Simulink no longer producers an algebraic loop error message. This workaround has no effect on the final hardware,
This problem is scheduled to be fixed in a future version of DSP Builder.
