Abstract: An instruction provider for providing a sequence of instructions based on a representation of a sequence of test vectors. Each instruction defines the provision of at least one test vector to a device under test. The instruction provider is configured to identify in the representation of the sequence of test vectors subsequences of test vectors which occur at least two times in the representation of the sequence of test vectors.

Abstract: System and method for implementing a memory test language compiler. The compiler includes a fast semantic processor for interpreting programming patterns in a test program, including converting stateful patterns into stateless patterns, and a device access timing generation module for generating an output based on the stateless patterns. The fast semantic processor can generate a closure for a device access line as the output. In the state of the closure, each device access line is in a closed state. A functor is formed from the interdependency of the variables and the loop dependency and a cache is used to handle recursive variables. The functor is propagated to device access lines as output, wherein the functor references the cache when needed.
