How do I stitch multiple MIF files generated by the Quartus II software into a single MIF file, for fPLL reconfiguration in Stratix V, Arria V and Cyclone V devices?

Description

You can stitch multiple Memory Initialization Files (MIF) generated by Quartus® II software into a single MIF file for fPLL reconfiguration in Stratix®  V, Arria®  V and Cyclone®  V devices using the script provided in the link below:

merge_mif.tcl

To use the script, follow the steps below:

1. Place the tcl file and the MIF files in the same folder.

2. Source the merge_mif.tcl in tcl console.

3. Type the following command to stich 2 mif files (e.g A.mif and B.mif) into output.mif.

Command : stitch A.mif  B.mif [output.mif]

Note : If you do not specify the optional [output.mif] paramater, it defaults to merged.mif.

4. In merged.mif, the content of B.mif comes after A.mif.

5. Repeat step 3 if you want to merge another MIF file (e.g C.mif) to merged.mif . You can stitch multiple MIF files together as long as the depth of the merged file does not exceed 512.
