'/Serializer1D/HDL1DSe' error occurred when invoking 'getOutputSizeImpl' method of 'hdl.serializer1D'

5 views (last 30 days)
Hello,
I got the following error when I tried to build a DSP model with a deserializer-serializer structure. This error only happened when the 'ValidOut' port was enabled on the serializer. This only happened in some of my models and was more likely to happen when there were downsampling blocks between the deserializer and serializer.
I attached a simple model with this problem. It would run if the 'ValidOut' was disabled. Any clue on why this happens? Thanks a lot!

I was able to avoid the error by setting the dimension of inputA to 1. Model attached.
