Method for abstraction of manufacturing test access and control ports to support automated RTL manufacturing test insertion flow for reusable modules

摘要

A system for RTL test insertion in an integrated circuit layout pattern includes a core module, a test wrapper, and a smart wrapper. The core module describes a function defined by logical elements, interconnections between logical elements, input pins and output pins. The test wrapper is adapted to encapsulate the core module and to create test pins representing the core module. The smart wrapper is adapted to encapsulate the test wrapper and to assign the test pins to a non-asserted state. The smart wrapper is adapted to place an assertion on one or more of the test pins for static or dynamic testing of the integrated circuit layout pattern.
