A. Board Revision History

This appendix catalogs revisions to the Stratix IV GX FPGA development board.

Table A–1 lists the versions of all releases of the Stratix IV GX FPGA development

board.

Single-Die Flash Version Differences

The single-die flash version of the Stratix IV GX FPGA development board is created

to replace the obsolete dual-die flash device with a single-die flash device. The two

flash devices are considered equivalent except for some software routines used to

access them because the single-die device has only one CFI table whereas the duel-die

device has two CFI tables.

To determine which flash your board is using, refer to the device part number

installed at U32. The single-die package is smaller than the dual-die version.

f For more information about the flash change and its application, refer to the Stratix IV

GX FPGA Development Kit User Guide.

Engineering Silicon Version Differences

The engineering silicon version of the Stratix IV GX FPGA development board is the

initial release of the board. This section describes the differences between the

engineering silicon and production silicon versions of the board.
