- Jul 25, 2026 Clock Domain Crossing: Synchronizers, Handshakes, and False Paths Why a flip-flop sampling an unrelated clock can go metastable, how a two-flop synchronizer bounds the failure rate, and how data buses cross domains without tearing. hardware engineering
- Oct 23, 2025 Metastability: What a Two-Flop Synchronizer Buys and What It Cannot Why a flip-flop that samples a changing asynchronous input can hover between logic levels, how the resolution failure rate falls exponentially with the time allowed, and why buses cannot be crossed one bit at a time. hardware engineering
- Oct 5, 2024 Setup and Hold Time, Metastability, and the Two-Flop Synchronizer Why a flip-flop needs its input stable around the clock edge, how a near-threshold sample resolves probabilistically, and how cascaded flops bound the failure rate. hardware engineering
