The only thing I can think of is that the erase action is writing something in the private registers ( see the last lines from the ep2s60 bsdl) : "The following private instructions must not be used as they"& "may render the device inoperable:"& " "& " 1100010000 "& " 0011001001 "& " 0000101001 "& " 0000010000 "& " "& "Customer should take precautions not to invoke these instructions"& "at any time. Contact Altera Applications for further assistance.";
