10 Questions
How is slack calculated in timing analysis?
By subtracting the arrival time from the required time.
What is slack in the context of timing analysis?
The difference between the required and arrival times.
What does positive slack indicate in timing analysis?
The circuit meets timing requirements.
What does negative slack indicate in timing analysis?
The circuit is not fast enough.
How does a timing analyzer account for different gate delays?
By defining delays separately for rising and falling transitions.
Define propagation delay time.
Maximum time from the input crossing 50% to the output crossing 50%.
What is contamination delay time?
Minimum time from the input crossing 50% to the output crossing 50%.
Explain the rise time.
Time for a waveform to rise from 20% to 80% of its steady-state value.
What does the term 'Edge rate' represent?
(tr + tf)/2, the average of rise time and fall time.
Why is propagation delay often referred to as simply 'delay'?
Propagation delay is usually the most relevant value of interest in chip design.
Explore the key concepts of delay and power optimization in chip design, focusing on the impact of wires and transistors. Learn about metrics like propagation delay time and contamination delay time for designing chips that work efficiently.
