This topic turns the section's theory into decisions. Given a signal and two clocks, it tells you which pattern to reach for, which direction-specific rules apply, and what each choice costs in latency, throughput, area, and verification.
Lesson | After it you can... |
|---|---|
Map any crossing type and clock ratio to a pattern and its main hazard. | |
Apply the slow-to-fast rules and examples. | |
Stretch and space fast pulses so none is lost. | |
Compare patterns by latency, throughput, area, and verification effort. |
Start with the matrix, then read the lesson for your crossing direction, and check the cost table before committing.
The crossing type (level, pulse, word, counter, stream, configuration, reset) and the clock ratio (slow-to-fast, fast-to-slow, or unknown).
