Chapter 3: Mapping Stratix IV Device Resources to HardCopy IV Devices
Designing with HardCopy IV I/Os
HardCopy IV ASICs offer the non-socket replacement flow to reduce design board
space and cost. Because HardCopy IV and Stratix IV device packages are different,
some Stratix IV device I/Os are not available in the HardCopy IV device. Table 3–9
shows the number of I/Os in each bank on Stratix IV and HardCopy IV devices for
the non-socket replacement flow.
