PCIe 6.0 introduces a major shift in power-state strategy: the real battle is no longer between L0 and L1—it is between L0p, L0s, and L1. In this blog, we explore how these states differ, why PCIe 6.0 changes the rules, and which one matters most moving forward.
In the demonstration, a data link was established using a Keysight arbitrary waveform generator (AWG) transmitting to a Cadence PHY receiver. The system demonstrated good bit error rate (BER) performance.
Compute Express Link (CXL) is revolutionizing data center architecture, with power management emerging as a key area of innovation. Among its power-saving mechanisms, the L0p (Low Power) state plays a pivotal role in reducing energy consumption during periods of low link activity.
Memory interleaving is a technique that distributes memory addresses across multiple memory devices or channels. Instead of storing data sequentially in one device, the system alternates between devices at a fixed granularity. It could help improve bandwidth, reduce latency, and enhance scalability. In the context of Compute Express Link (CXL), memory interleaving is facilitated by the HDM (Host-Managed Device Memory) Decoder.
In semiconductor design, projects are remembered for their extremes—legendary successes and cautionary failures. The difference often hinges on when problems are discovered. A bug found late in development can derail timelines and budgets. This is why "shifting left"—moving testing and validation earlier in the process—is now a critical strategy for innovation.
As chip designs grow larger and more complex, they become increasingly difficult to manufacture as a single piece of silicon. Yields (the percentage of properly functioning chips from a semiconductor wafer) decrease significantly with larger die sizes.
