# FILE DESCRIPTION
# ----------------
# This file contains a simple script to automatically apply
# IO standards and other IO assignments for the UniPHY memory
# interface pins that connect to the memory device. The pins
# are automatically detected using the routines defined in
# the hps_sdram_p0_pin_map.tcl script.
# All the memory interface parameters are defined in the
# hps_sdram_p0_parameters.tcl script
