Check for infinite and continuous sample time sources

Check ID: com.mathworks.HDL.ModelChecker.runSampleTimeChecks

Check ID: com.mathworks.HDL.ModelAdvisor.runSampleTimeChecks

Check source blocks with infinite or continuous sample time.


By default, the Sample time parameter of a Constant block is inf. During HDL code generation, HDL Coder™ does not resolve inf sample times of Constant blocks if the sample times propagate to the device under test (DUT) output. For more details, see the HDL Code Generation section of the Constant block page.

This check reports a warning if your design contains source blocks that have an infinite or continuous sample time.

Results and Recommended Actions

To fix this warning, click Modify Settings to update the Sample time of these source blocks to inherit through back propagation. That is, HDL Coder sets Sample time of these blocks to -1. You can then rerun the check.
