Challenges in Signal Quality Testing
As AI and high-speed computing evolve, the demand for high-speed data transmission continues to rise. This surge in demand introduces significant challenges to maintaining signal integrity, underscoring the importance of PCIe electrical signal measurements.
PCIe Signal Quality Measurement
Extensive Measurement Effort:
Tx testing of an 8-slot (x16) server based on PCIe 5.0 involves up to 4,608 eye patterns and takes 40–41 days to complete.
Compromised Test Scope:
Industry challenges have led to a 50-80% reduction in full test coverage, significantly compromising quality assurance.
Quality Assurance Impact:
Manual testing processes increase the risks of errors.
AI/Automation Demand:
A non-compromising solution is needed to optimize both efficiency and accuracy.
