Hi KhaiY, the vhdl file contains a component named BRAM_16x1S as part of the archive BRAM16x2 archtecture. It works splendidly as it is in Xilinx ISE 14.6. But Quartus 13.x fails to compile this same vhdl file. This is that file:

I'll add it hereby as attachement too.
Thanks again for taking the time to look into the problem!
