Synthesis of ROM & Synthesis Attributes

I did add the attribute with q as the signal, and this did work. I removed the Quartus settings for "synthesize any ROM size" and after compilation the ROM was placed into embedded memory. This is helpful because when the source VHDL is made with these attributes the downstream configuration options in Quartus don't have to be set, which is what I was aiming for. James
