Cross-Reference File (.xrf) Definition

An ASCII text file (with the extension .xrf), that is generated by a third-party synthesis tool, and which allows the Intel^® Quartus^® Prime software to locate or cross-probe an object from the Intel^® Quartus^® Prime source design file to the third-party tool source design file.
