8. Migrating Stratix II Device

Resources to HardCopy II

Devices

Introduction

Altera® HardCopy® II devices and Stratix® II devices are both

manufactured on a 1.2-V, 90-nm process technology and offer many

similar features. Designers can use the Quartus® II software to migrate

their Stratix II design to a HardCopy II device. The Quartus II software

ensures that the design revision targeting a HardCopy II device retains

the same functionality as the original Stratix II design.

Beginning with version 5.0 of the Quartus II software, you can select a

HardCopy II companion device from the Device Settings dialog box

(Device menu). Selecting a HardCopy II device as a companion device is

similar to adding another Stratix II device in the migration device chain.

The Quartus II software compiles the design to use the common resources

available in all of the selected Stratix II devices and the selected

HardCopy II devices. The HardCopy II companion device becomes the

target device when you switch to the HardCopy II flow from this Stratix II

flow later in the Quartus II project compilation.

For more information on compiling with Stratix II and HardCopy II

companion revisions using Quartus II software, refer to the Quartus II

Support for HardCopy II Devices chapter of the HardCopy Series Devices

Handbook.

When you select a HardCopy II companion device, you can set the

Quartus II Compiler to limit the design to the minimum resource

availability of memory blocks and available logic for digital signal

processing (DSP) from either the targeted Stratix II or HardCopy II

companion device. Additional limitations also include I/O pin

assignments and phase-locked loops (PLLs). This document is a guide for

designers migrating Stratix II designs into HardCopy II devices. This

document highlights resources that are not supported by the selected

Stratix II and HardCopy II companion device pair or any resource

differences between Stratix II devices and the HardCopy II device.
