Industry Drivers
Why top-tier design houses mandate black-boxing for high-performance SoCs.
Industry Standard Practice
Verification & Testing
Choosing the right methodology for the verification plan.
📦
Black-Box Testing
- ✔ Logic is verified via Input/Output behavior only.
- ✔ Ideal for 3rd Party IP where source code is unavailable.
- ✔ Focuses on system-level integration and protocol compliance.
- ✔ Faster setup; does not require deep logic knowledge.
🔍
White-Box Testing
- ⚡ Internal paths and code coverage are fully visible.
- ⚡ Required for internal modules to find logic bugs.
- ⚡ Allows for specific corner-case bug hunting.
- ⚡ High effort; requires understanding the full RTL.
Strategic Impact Synthesis
While black-boxing offers high security and speed, it trades off total logic control. Modern SoC managers balance these two states based on the IP source.
Key Insight
Use Black Boxes for Verified Vendor IPs; use White Boxes for In-house RTL Development.
