1. HardCopy IV Design Flow Using the
Quartus II Software
HIV52001-2.1
This chapter provides recommendations for HardCopy^® IV development, planning,
and settings considerations in the Quartus^® II software. Beginning with the
Quartus II software version 9.1, both companion and compilation for HardCopy IV
ASICs are supported. During HardCopy IV ASIC development, the Quartus II
software ensures that both the Stratix IV FPGA and HardCopy IV ASIC have
compatible pins, I/O standards, logic, and other resources.
HardCopy IV Development Flow
In the Quartus II software, two methods are available for the HardCopy IV
development flow: Stratix IV device first flow and HardCopy IV device first flow.
■ Stratix IV device first flow—Design the Stratix IV device first for system functional
verification and then create the HardCopy IV companion device. Performing
system verification early helps reduce overall total project development time.
■ HardCopy IV device first flow—Design the HardCopy IV device first and then
create the Stratix IV companion device for system functional verification. This
method more accurately predicts the maximum performance of the HardCopy IV
ASIC during development. If you optimize your design to maximize
HardCopy IV ASIC performance, but are unable to meet your performance
requirements with the Stratix IV FPGA, you can still map your design with
decreased performance requirements for in-system verification.
1 Whichever design flow you choose for your HardCopy IV development, both the
target design and the companion device design must be in one Quartus II project.
Designing with the Stratix IV Device First Flow
The HardCopy IV development flow beginning with the Stratix IV prototype is very
similar to a traditional Stratix IV design flow, but requires that you perform a few
additional tasks to map the design to the HardCopy IV companion device:
1. Choose a Stratix IV device for prototyping.
2. Specify a HardCopy IV device for conversion.
3. Compile the Stratix IV design.
4. Create and compile the HardCopy IV companion revision.
5. Compare the HardCopy IV companion revision compilation to the Stratix IV
device compilation.
6. Generate the handoff files and reports.
7. Archive the design and send it to Altera to start the back-end design process.
