#Convert Xilinx Mif to Altera MIF
#Ex of How to run Script for a 16x8 (16 bit wide, 8 deep) Xilinx Block RAM:
#python X_altera_mif_conversion.py -d 8 -w 16 -i Xilinx_mif.mif -o intel_mif.mif
#If your Xilinx MIF (Xilinx_mif.mif) is a 8x16 (dxw) MIF generated in Vivado/ISE, the command above will generate a intel MIF file intel_mif.mif in the correct format that will pass Quartus synthesis.
