I am trying to convert a block to HDL using HDL coder with IPcore genration as an option.It throws assertion failed Chareterizationkeygenerator error. Error using hdlcoder.pirctx/doCriticalPathEstimation Assertion failed: b:\matlab\src\cgir_hdl\target_analysis\characterizationkeygenerator.cpp:45:val
Error in slhdlcoder.HDLCoder/makehdl
Error in slhdlcoder.HDLCoder/makehdlturnkey

Error in Simulink.ModelAdvisor/executeCheckCallbackFct
Error in Simulink.ModelAdvisor/run
Error in Simulink.ModelAdvisor/runCheck
Error in ModelAdvisor.Node/runTaskAdvisor
This is the error list i got .I thought the error might be an issue in Model advisor being outdated and ran it task.mode. But it still throws the same error. Can anyone explain the reason why this error occcurs?
I am usinn arrow Sockit with altera Cyclone v . Thanks in advance

Hi Suneel, thanks for bringing up this issue to our notice. it is a bug. you can work around this problem by turning off CriticalPathEstimation feature. you can do that in many different ways. you can set this off on the model using
hdlset_param(<yourmodelname>, 'CriticalPathEstimation', 'off')
from workflow advisor, in HDL Code Generation section, uncheck "Generate high-level timing critical path report".
This change will not affect the quality of the code generated by HDL Coder; however, this will not give you an early report on estimated critical path in your design.
To understand the problem further, I need following information:
1. Model to reproduce the issue
2. Matlab version.
you can send me these details to

Do you have any Rate Transition blocks in your model? Try removing the Rate Transition blocks from your model and try again. Also, you can try using R2017a_prerelease since the issue does not exist in R2017a_prerelease.

I dont have any rate transition blocks it is a single rate all over the model. I think i don't have access to pre release probably because of license issues. Can you suggest further on anything related to Model advisor?
