boundary scanThe use of scan registers to capture state from device input and output pins. IEEE Standard 1149.1-1990 describes the international standard implementation (sometimes called JTAG after the Joint Test Action Group which began the standardisation work).

boundary value analysis
A test data selection technique in which values are chosen to lie along data extremes. Boundary values include maximum, minimum, just inside/outside boundaries, typical values, and error values. The hope is that, if a systems works correctly for these special values then it will work correctly for all values in between.

In domain theory, a subset S of a cpo X is bounded if there exists x in X such that for all s in S, s <= x. In other words, there is some element above all of S. If every bounded subset of X has a least upper bound then X is boundedly complete.("<=" is written in LaTeX as \subseteq).

bound variable1. A bound variable or formal argument in a function definition is replaced by the actual argument when the function is applied. In the lambda abstraction
\ x . Mx is the bound variable. However, x is a free variable of the term M when M is considered on its own. M is the scope of the binding of x. 2. In logic a bound variable is a quantified variable. See quantifier.
