In the Intel® Quartus® Prime Pro Edition software the Platform Designer will append unique suffixes (hashes) to the IP component file names during generation to ensure uniqueness of the file. The uniqueness of the file is neccesary because the IP component is dynamic and the RTL for the IP is generated during runtime based on the input parameters. A given set of parameter values produces the same hash for each generation. This methodology ensures no collisions between the multiple variants of the same IP.
This information is scheduled to be added in a future release of the Intel® Quartus® Prime Pro Edition User Guide: Platform Designer.
