NanoTime complements dynamic simulation and is able to exhaustively check for all internal timing and noise interactions. It creates block-level timing models that can be used with PrimeTime® for full-chip signoff. It can also leverage Synopsys simulators Hspice and FineSim to deliver the highest accuracy.
What is NanoTime?
nanoTime() method returns the current value of the most precise available system timer, in nanoseconds. The value returned represents nanoseconds since some fixed but arbitrary time (in the future, so values may be negative) and provides nanosecond precision, but not necessarily nanosecond accuracy.
What is timing verification in DSD?
Dynamic timing verification refers to verifying that an ASIC design is fast enough to run without errors at the targeted clock rate. This is accomplished by simulating the design files used to synthesize the integrated circuit (IC) design.
Is nanoseconds and milliseconds the same?
The time in milliseconds is equal to the nanoseconds divided by 1,000,000. Nanoseconds and milliseconds are both units used to measure time. Keep reading to learn more about each unit of measure.
How Fast Is system nanoTime?
nanoTime() takes about 25 nanoseconds. Not great, not terrible. It implies it’s probably unwise to use System. nano() to measure anything taking less than a few dozens of nanoseconds as the overhead of our instrumentation would be higher than the measured interval.
What is the difference between functional and formal verification?
Functional Verification is checking your DUT’s behaviour on different inputs combinations… Formal Verification is checking different possible States covered by you DUT…
How long is a pico second?
What exactly is a picosecond? It is one trillionth of a second. To make it look cleaner, scientists and researchers usually write a picosecond like this: 10-12. Another way of writing that is 0.000000000001 of a second.
Is system currentTimeMillis thread safe?
public static long currentTimeMillis() // Returns the current time in milliseconds. Pros: It is thread safe. Thread safety means that if this method is called between two or more different threads, it will not return erroneous results.
