2.7.3. Consolidating the .sdc in the Top-Level Design

When the partition designers complete their designs, they export the results to the project lead. The project lead receives the exported .qxp files and a copy of the .sdc with partition-specific constraints.

To set up the top-level .sdc constraint file to accept the .sdc files from the separate Intel® Quartus® Prime projects, the top-level .sdc should define the hierarchy variables specified in the partition .sdc files. List the variable for each partition and set it to the hierarchy path, up to and including the instantiation of the partition in the top-level design, including the final hierarchy character ”|”.

To ensure that the .sdc files are used in the correct order, the project lead can use the Tcl Source command to load each .sdc.
