sink pin
The pin located at the end of the timing path. This pin is usually the one where arrival time and required time
are evaluated for path violation.
skew
The difference between the clock insertion delay to the clock pin of a sink register and the insertion delay to
the clock pin of a source register.
slack
The difference between the arrival time and the required time at a specific pin, generally at the data pin of a
sequential component.
slew rate
The time needed for a signal to transition from one logic level to another.
source pin
The pin located at the beginning of a timing path.
STA

static timing analysis
.
standard delay format (SDF)
Standard Delay Format, a standard file format used to store design data suited for back-annotation.
static timing analysis
An efficient technique to identify timing violations in a design and to ensure that all timing requirements are
met. It is well suited for traditional synchronous designs. The main advantages are that it does not require
input vectors, and it exclusively covers all possible paths in the design in a relatively short run-time.
synopsys design constraint (SDC)
A standard file format for timing constraints. Synopsys Design Constraints (SDC) is a Tcl-based format used
by Synopsys tools to specify the design intent, including the timing and area constraints for a design.
Microsemi SoC tools use a subset of the SDC format to capture supported timing constraints. You can
import or export an SDC file from the Designer software. Any timing constraint that you can enter using
Designer tools, can also be specified in an SDC file.
timing constraint
A requirement or limitation on the design to be satisfied during the design implementation.
timing exception
An exception to a general requirement usually applied on a subset of the objects on which the requirement
is applied.
timing requirement
A constraint on the design usually determined by the specifications at the system level.
