Hi,

I have a Model which I am creating a "Generic Xilinx Platform" using IP Core Generation workflow within HDL Workflow Advisor.

I have "Balance delays" turned on.

Workflow Advisor fails giving an Error of "Delay balancing unsuccessful because Signal rate of inf found."

The offending blocks are from the Simulink Library, an example is "Compare to zero" which is HDL Coder compatible but if you look under the mask then you find the offending constant that has a SampleTime of inf.

Another example I have seen is Counters from the Simulink Library, which when you look under the mask have multiple constants within them with SampleTimes of inf.

Is there a checkBox somewhere that I can tick to ignore these errors for "Delay Balancing". Obviously we can't edit your fundamental Simulink Library blocks....

The original Model was created in 2014a, but if I look under the Mask of the 2020a blocks then they still have the "inf" SampleTimes.

Many Thanks,

Stuart
