Reduce Development Time, System Complexity, and Certification Risk
Qualified Functional Safety Data Package
Industrial automation, transportation, the smart grid, automotive, military and aerospace, and
medical require that machinery and products are highly reliable, safe, and certified for functional
safety. Safety is a central requirement when you develop machinery that must comply with
worldwide established safety standards such as IEC 61508 and ISO 26262.
When you develop a safe product, you need to consider safety as a core system functionality.
Design challenges include:
• Adopting quality management standards, a “safe” design methodology, and safety concepts
• Accounting for additional project effort (time and technology), resulting in longer time to market
and higher cost of ownership
Impact of Functional Safety
Typical design steps to develop an application, before safety:

If you add some of the required steps to design a safe application and achieve functional safety certification (shown in
yellow), you can see the significant project complexity:
Project Startup,
Risk Analysis
Architecture
Development

Having immediate access to qualified semiconductor data, intellectual property (IP), development flows, and design
tools from a vendor like Altera can help you significantly shorten your overall project timeline by 1 ½ years to 2 years:

Accelerating Development
To simplify and speed up the certification
process for faster time to market, we worked
with TÜV Rheinland and obtained approval for
Altera® FPGA devices, IP, our established safety
FPGA design flow, and development tools for
safety designs up to the Safety Integrity Level 3
(SIL3). This certification means that our tools,
methodologies, and devices are sufficiently free
of systematic errors.

Altera FPGAs Provide Flexible Safety Solutions
Figure 1 illustrates a typical industrial controller application. It integrates standard (“non-safe”)
and safety functions with very few board components using FPGA devices, such as the Altera
Cyclone® FPGA, and a soft processor core, such as the Nios® II processor. In this example, all
three embedded controllers are Nios II soft-core processors, each with an individual custom
peripheral set.

With such a safety-focused
architecture for a SIL3
certified application, you can
reduce the total cost of owner-
ship, design footprint, and
power consumption while
meeting the global requirements
for functional safety.

failures. Using an option card

increases the cost significantly.
Integrating a SIL3 “safe” solution in a pre-qualified FPGA with standard application functions
on the main board not only lowers the safety cost footprint, but it also enhances system
flexibility and shortens development time. It is designed with safety as a core system function-
ality in mind.
If you are concerned about the lack of flexibility, long development times, or device
certification issues that come with traditional safety architectures, Altera’s FPGAs are the
ideal solution.
