Software tools ease AUTOSAR compliance Design How-To 2/9/2012 Post a comment The AUTOSAR initiative is tackling the industry-wide constraints of complexity, competition, and cost. AUTOSAR provides incentives for manufacturers to replace their proprietary software/hardware interfaces with standardized ones linked to an independent architectural layer.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
