Description: To achieve TB/s bandwidth, maintaining signal integrity in high-speed channel is mandatory. In the high-speed channel, not only channel parameters but also non-linear power/ground noise generated by SSO noise affect signal integrity. However, conventional simulators and eye-diagram estimation methods fail to accurately estimate the eye-diagram considering these noises. In this study, we propose fast and accurate statistical method which considers non-linear power/ground noise and SSO noise. The proposed method is applied for signal integrity analysis in HBM interposer channel. Proposed method estimates impacts of power/ground and SSO noise on HBM channel. Based on proposed method, hierarchical PDN design is optimized.

Takeaway: In this study, we propose statistical method which considers non-linear power/ground noise and SSO noise. The proposed method is applied for signal integrity analysis in HBM interposer channel. Proposed method estimates impacts of power/ground and SSO noise on HBM channel. Based on proposed method, hierarchical PDN design is optimized.
