摘要:
The present invention provides a method, an apparatus, and a computer program product for applying external clock and data patterns for TTP-LBIST. A simulation model for the logic under test is set up in a simulator. Next, a user sets up an external LBIST block, which comprises pre-verified internal clock and data pattern logic, and connects this block to the logic in the simulation model. The internal clock and data pattern logic provides the input patterns used in OCPG modes of LBIST. This internal clock and data pattern logic is already verified through the design effort. Therefore, the internal pattern generators become the external pattern generators in the simulation model. The external LBIST block applies the external clock and data patterns, and subsequently, the user receives and processes these output patterns to determine if the logic operates correctly.

The invention relates to a method and system for testing bit failures in array elements of an electronic circuit. Said method comprising the steps of changing an original hardware representation (DD) of the array such that errors can be injected in a memory by manipulation of associated read and/or write logic of the memory via input signals, building an emulator model (SME) from said changed hardware representation for emulating the array, and injecting errors into the changed hardware representation for determining the array to get stick capabilities.
