Full quote Constraint blocks can be used to specify a network of constraints that represent mathematical expressions such as {F=m*a} and {a=dv/dt}, which constrain the physical properties of a system. Next snippet Such constraints can also be used to identify critical performance parameters and their relationships to other parameters, which can be tracked throughout the system life cycle.

Related snippets (backlinks) A constraint block is defined by a keyword of «constraint» applied to a block definition. Properties of this block define parameters of the constraint, with the exception of properties that hold internally nested usages of constraint blocks. The usage of a constraint block is distinguished from other parts by a box having rounded corners rather than the square corners of an ordinary part. A parametric diagram is a restricted form of internal block diagram that shows only the use of constraint blocks along with the properties they constrain within a context. Figure D.26 defines the various model elements that will be used to conduct analysis in this example. It depicts each of the constraint blocks/equations that will be used for the analysis, and key relationships between them. Visit also Visit also (backlinks) Flags
