Dear DBart1,

Thank you for joining this Intel Community. I am truly apologize for the delay in response due to long holiday in my region.

The issue you are facing is a known issue but it is not fix in the IP. As a workaround, we have published a KDB on how to cut the failing path in this link --> https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/solutions/rd08142014_213.html

Hope this helps.

Thanks

Regards,
