Dynamic mode switching allows the designer to set up each Stratix II
DSP block to dynamically switch between the following three modes:
■
■
■
Each half of a Stratix II DSP block has separate mode control signals.
Since DSP block functions are implemented in HardCopy II devices using
HCells, HardCopy II devices do not support dynamic mode switching. If
this feature is used, the Quartus II software flags the DSP implementation
and does not allow you to migrate the design. The fitter reports that all
HardCopy II devices are not compatible with the design. To migrate your
Stratix II design to a HardCopy II companion device, disable dynamic
switching in the DSP blocks.
For more information on the Stratix II DSP operational modes, refer to
the Stratix II Device Handbook.
HardCopy II memory blocks can implement various types of memory
with or without parity, including true dual-port, simple dual-port, and
single-port RAM, ROM, and FIFO buffers. HardCopy II devices support
the same memory functions and features as Stratix II FPGAs.
Functionally, the memory in both devices are identical. However, the
number of available memory blocks differs based on density
Since device functionality is fixed in HardCopy II devices, M4K block
contents cannot be preloaded or initialized with a MIF when they are
configured as RAM. When the M4K blocks are used as ROM, they will
initialize to the design’s ROM contents.
When using the non-registered outputs mode for the HardCopy II M4K
memory block, the outputs power up uninitialized. When using the
registered outputs mode for the HardCopy II M4K memory blocks, the
