Document Table of Contents Registering the SDC-on-RTL SDC File

For the Early Timing Analysis flow, your design must include an associated SDC-on-RTL SDC file. You must register the SDC file with Intel® Quartus® Prime software by adding it to the QSF, as shown in the following image:

Figure 39. Registering the SDC-on-RTL SDC File
Note: Alternatively, you can also associate an SDC-on-RTL files with your project from the Timing Analyzer using the File menu.

SDC files are registered with an Intel® Quartus® Prime software project through the following RTL_SDC_FILE assignment:

set_global_assignment -name RTL_SDC_FILE sdc_on_rtl_file.sdc
Note: Although you can use any file extension, Intel® recommends using an intuitive file extension, for example, rtlsdc, to help distinguish SDC-on-RTL SDC files from the conventional Intel® Quartus® Prime software SDC files if your design uses both.
