Design a 2 lb. radio… Over a 10 year period… that will run for ½ hour… and sell for $4000… for use by New York stock brokers… to raise their social status

Design a 4 oz. radio/computer/camera/TV/stereo/GPS… Over a 9 month period… that will run for 2 days… and sell for $0 (after rebate)… to connect every human on the planet… to instantly exchange every form of information: voice, text, web, photo, video…

The Recipe for High Quality Smartphones

1. Go Standard, Go MIPI!

2. Use verification IPs to validate connectivity and compliance

3. Catch the bugs when they aren’t ready!

4. Know when you are done!

Go Standard, Go MIPI! • Leveraging proven

technologies

• Reusing IPs, reducing cost

• Enjoying a supportive eco-system

• Testing labs • Verification IPs • Engineering Knowledge

• Shortening Time To Market!

• What is a Verification IP (VIP)?

- SW model, based on the MIPI specification (CSI, DSI, UniPro, LLI etc.)

- Designed to run against RTL implementation at cycle accurate level

- Test the design in ‘real life’ scenarios and ensure compatibility with the standard

Catch Bugs Before They Catch You!

• Traditional testing methods cannot handle the growing Smartphone design complexity

• Random testing, generating relevant scenarios is essential for catching interfaces bugs
