3. Introduction
Static Timing Analysis is one of the techniques used to verify the timing of a digital design.
The term timing analysis is used to refer to either static timing analysis or the timing simulation.
Analysis does not depend upon the data values being applied at the input pins.

4. Continued..,
In STA a stimulus is applied on input signals resulting behavior is observed and verified.
The purpose of static timing analysis is to validate if the design can operate at the rated speed.

5. Basic figure of STA

6. Functionality of STA The DUA is the design under analysis
Examples of timing checks are setup and hold checks
Setup checks : It ensures that the data can arrive at a flip-flop within the given clock period
Hold checks : It ensures that a flip-flop captures the intended data correctly

7. Functionality of STA
These checks ensure that the proper data is ready and available for capture and latched in for the new state
Entire design is analyzed once and the required timing checks are performed for all possible paths
STA is a complete and exhaustive method for verifying the timing of a design.

8. Functionality of STA
The DUA is typically specified using a hardware description language such as VHDL or Verilog HDL
The external environment including
a)Clock definitions b)SDC
The timing reports are in ASCII form with multiple columns and column showing one attribute of the path delay

9. Advantages of STA
Static timing analysis is a complete and exhaustive verification of all timing checks of a design
Timing analysis methods such as simulation can only verify the portions of the design that get exercised by stimulus
Faster and simpler way of checking and analyzing all the timing paths

10. What is Crosstalk and Noise
Traces are used to make the connections between various portions of the circuit
Interconnect induces noise and crosstalk
Crosstalk means interference
Noise means unwanted things (signal)

11. Causes of Crosstalk and Noise
Design functionality and its performance can be limited by noise
Noise occurs due to crosstalk (interference) with other signals or due to noise on primary inputs or the power supply
Limit the frequency of operation and it can also cause functional failures
