Properties of this block define parameters of the constraint, with the exception of properties that hold internally nested usages of constraint blocks. Full quote 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. Next snippet Related snippets A constraint block is a block that packages the statement of a constraint so it may be applied in a reusable way to constrain properties of other blocks. A constraint block typically defines one or more constraint parameters, which are bound to properties of other blocks in a surrounding context where the constraint is used. All properties of a constraint block are constraint parameters, with the exception of constraint properties that hold internally nested usages of constraint blocks. A constraint property is a property of any block that is typed by a constraint block. It holds a localized usage of the constraint block. Binding connectors may be used to bind the parameters of this constraint block to other properties of the block ... A constraint property may be shown on a parametric diagram using a rectangle with rounded corners. This graphical shape distinguishes a constraint property from all other properties and avoids the need to show an explicit «constraint» keyword. Otherwise.. Constraint blocks provide a mechanism for integrating engineering analysis such as performance and reliability models with other SysML models. 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. A constraint block includes the constraint, such as {F=m*a}, and the parameters of the constraint such as F, m, and a. Constraint blocks define generic forms of constraints that can be used in multiple contexts. For example, a definition for Newton’s Laws may be used to specify these constraints in many different contexts. The usage of a constraint binds the parameters of the constraint, such as F, m, and a, to specific properties of a block, such as a mass, that provide values for the parameters. 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.
