1 Early shipments of the Nios development board, Stratix II
edition use an EP2S60F672C5ES device. This is a fully tested
engineering sample (ES) device. However, it has a known issue
affecting the M-RAM blocks. The issue can be worked around
easily, but some consideration is required when migrating
designs based on this device to a non-ES device. There is a label
near the FPGA; if the letters “ES” appear on the label, the device
is an engineering sample.
f For details, refer to the Stratix II FPGA Family Errata Sheet and the
documented example designs included in the Nios II Development Kit.
