Chapter 3: Mapping Stratix IV Device Resources to HardCopy IV Devices
Designing with HardCopy IV I/Os
The sizes of each bank are 24, 26, 32, 40, 42, 48, or 50 I/O pins (including up to two
dedicated input pins per bank). During mapping from a smaller device to a larger
device, the bank size increases or remains the same but never decreases. For example,
banks may increase from a size of 24 I/O to a bank of size 32, 40, 48, or 50 I/O, but will
never decrease.
Table 3–7 summarizes the number of I/O pins available in each I/O bank for all
companion pairs of Stratix IV GX and HardCopy IV GX devices.
