24.1.2.1 Migration Libraries

In addition to the standard Microchip libraries, Microchip provides a set of migration libraries. These libraries contain cores supported in 3.1.1u1 and earlier versions of the Designer Series software and cores possibly needed to retarget designs from a different Microchip family. Microchip does not recommend using the migration libraries on new designs. The Verilog migration libraries are installed in the “<microchip_install_directory>/lib/vlog/<act_fam>_mig.v” directories.
