The report example in Figure 5–4 shows the resource comparisons for a

design compiled for a Stratix II EP2S130F1020 device. Based on the

report, the HC230F1020 device in the 1,020-pin FineLine BGA® package

is an appropriate HardCopy II device to migrate to. If the HC230F1020

device is not specified as a migration target during the compilation, its

package and migration compatibility is rated orange, or Medium. The

migration compatibilities of the other HardCopy II devices are rated red,

or None, because the package types are incompatible with the Stratix II

device. The 1,020-pin FBGA HC240 device is rated red because it is only

compatible with the Stratix II EP2S180F1020 device.

Figure 5–5 shows the report after the (unchanged) design was recompiled

with the HardCopy II HC230F1020 device specified as a migration target.

Now the HC230F1020 device package and migration compatibility is

rated green, or High.

HardCopy II

Companion

Device Selection

In the Quartus II software, you can select a HardCopy II companion

device to help structure your design for migration from a Stratix II device

to a HardCopy II device. To make your HardCopy II companion device

selection, on the Assignments menu, click Settings. In the Settings dialog

box in the Category list, select Device (Figure 5–6) and select your

companion device from the Available devices list.

Selecting a HardCopy II Companion device to go with your Stratix II

prototype constrains the memory blocks, DSP blocks, and pin

assignments, so that your Stratix II and HardCopy II devices are

migration-compatible. Pin assignments are constrained in the Stratix II

design revision so that the HardCopy II device selected is pin-compatible.

The Quartus II software also constrains the Stratix II design revision so it

does not use M512 memory blocks or exceed the number of M-RAM

blocks in the HardCopy II companion device.
