Unlike other industry sectors, the challenge in designing a SoC for automotive doesn't involve working at bleeding edge technology nodes - it's only now starting to focus around 28nm. At this well-established and high yield node the automotive sector is seeking optimum dielectric isolation (leakage current v speed trade off).
When choosing a project team to design your automotive SoC, they will have to take into account the specific design rules associated with,
- High Temperature Operating Life (HOTL)
- Automotive Safety Integrity levels (ISO26262 ASIL A-D)
- Testing the design to a reliability prediction program, (SN29500/TR62380)
in order to supply you with a SoC that is compliant to stringent industry safety standards.
With customer Power, Performance and Area targets, Time to Market and compliance with these design rules, you need to start as early as possible in the design process with a robust verification strategy. This will underpin the success of your design as you progress through DfT and into Physical Implementation, using the following techniques:
- Functional Verification
- Formal Verification Techniques
- DfT for Automotive
- DFM aware Physical Design
- ESD Design Technique
- Power Management
Current verification methodologies, such as SystemVerilog, assertion based verification (ABV), UVM and metric driven verification, will help you to “shift left” in the design process.
In addition, the latest DfT techniques should be applied to increase the testability of the design and reduce production test times.
Thirdly, considerations for the Physical Implementation of the SoC. Using the correct software tools is vital as it will give you the necessary design checking, version management, register generation and documentation support adherence to regulatory compliance mandates such as DO-254 and ISO 26262.
Key to your success will be the awareness and experience of your engineering team in working to specific automotive design standards, and making sure that your verification strategy starts as early as possible in the design process.
