Signal Integrity (SI) / Power Integrity (PI) or Thermal issues:
1. Your PCB does not work after multiple re-spins, causing a lot of delays for the market ?
2. Your company wasting a lot of money on design iterations ?
3. Your design does not work across corners, i.e.. Typical/Fast/Slow, Cold/Hot, Low/High Voltage,…?
4. Your design does not meet system timings ?
5. Your design has no or low system margins, i.e.. Signal Eye-height/Width failed or low margin?
6. Failed EMC/EMI test after the design is completed ?
7. Cooling system is not good cause processor/internal component temperatures too high, cause damages?
8. The customer is complaining, but are you clueless ?
