Abstract: A method performed by a software design tool for providing an algorithm to a BIST controller that tests memory within a circuit. The method includes reading a description of a user defined test algorithm for a BIST controller, translating the description into an in-memory representation of the user defined algorithm, and reading a memory model selected by a user. The in-memory representation of the user-defined algorithm is associated with the selected memory model. From the association an HDL description of a BIST controller is generated. The HDL description is operable to apply the user defined algorithm to a memory corresponding to the selected memory model.
