Patch created on July 11 2013 Patch Case#: 129568 //**************************************************************** Problem: ALTASMI_PARALLEL just support for 4BYTEADDREN since it only allows user to operate EPCQ256 in 4-byte addressing mode. As Stratix IV required EPCQ256 in 3-byte addressing mode for configuration, 4BYTEADDREX support is needed to enable EPCQ256 to be used with Stratix IV. Solution:Adding 4BYTEADDREX operation in ALTASMI_PARALLEL to enable support of EPCQ256 with Stratix IV. Caution - You must either have previously installed the Quartus II 13.0 software or must install the Quartus II 13.0 software before installing this patch.
