Notes to Table 3–4:
(1) This is the number of ASIC-equivalent gates available in the HardCopy IV E base array, shared between both adaptive logic module (ALM) logic
and DSP functions from a Stratix IV E FPGA prototype. The number of usable ASIC equivalent gates is bounded by the number of ALMs in the
companion Stratix IV E FPGA device.
(2) HardCopy IV E devices do not have dedicated MLABs, but the Stratix IV E MLAB features and functions are supported in HardCopy IV devices.
(3) This device has 12 PLLs in the F1517 package and 8 PLLs in the F1152 package.
HardCopy IV ASICs offer pin-to-pin compatibility to the Stratix IV prototype, making
them drop-in replacements for FPGAs. Due to this compatibility, the same system
board and software developed for prototyping and field trials can be retained,
enabling faster time-to-market for high-volume production.
HardCopy IV devices also offer non-socket replacement mapping for further cost
reduction. For example, the EP4SE230 device in the 780-pin FBGA package can be
mapped to the HC4E25 device in the 484-pin FBGA package. Because the pinout for
the two packages are not the same, a separate board design is required for the
Stratix IV device and the HardCopy IV device.
1 For the non-socket replacement path, select I/Os in the Stratix IV device that can be
mapped to the HardCopy IV device. Not all I/Os in the Stratix IV device are available
in the HardCopy IV non-socket replacement device. Check pinout information for
both the Stratix IV device and the HardCopy IV device to ensure that you can map
successfully, and select the HardCopy IV companion device when designing for the
Stratix IV device.
Table 3–5 and Table 3–6 show available I/O pin counts by package for each Stratix IV
and HardCopy IV companion pair.
