ID:14566 The Fitter cannot place <number of failed cells> periphery component(s) due to conflicts with existing constraints <failed cell summary>. Fix the errors described in the submessages, and then rerun the Fitter. The Intel FPGA Knowledge Database may also contain articles with information on how to resolve this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number.

CAUSE: The Fitter detected conflicts between existing design constraints that makes it impossible to legally place all periphery components.

ACTION: Details on the errors affecting each periphery component are summarized as submessages. Review the errors and modify either the design or existing design constraints.
