The P1500 DFT Disclosure Document: A Standard to Communicate Mergeable Core DFT Data
نویسندگان
چکیده
While the IEEE P1500 standards working group is on the verge of recommending a standard test interface for "non-mergeable" cores, a need was felt to adopt a standard methodology to achieve easy test interoperability for "non-merged" core (RTL, gate level) integration. A task force was formed under the P1500 working group investigating this issue and came up with a recommendation. DFT Disclosure Document (DDD) was the outcome of this exercise. The DDD, targeted to be an IEEE standard recommended practice document, aims at capturing the DFT related experience the core provider would like to share with the integrator to facilitate easy test integration. This paper presents the objective and structure of this document along with some use models from participating companies as well as an example.

IEEE P1500, a Standard for System on Chip DFT
This document briefly describes the upcoming standard IEEE 1500 [4], titled "Standard Testability method for Embedded Core-based Integrated Circuits". IEEE P1500 defines a mechanism for the test of digital aspects of core designs within a System-onChip (SoC). This mechanism is a scaleable standard architecture for enabling test reuse and integration for embedded cores and associated circuitry.

– Core-based testing, which is described by the proposed IEEE standard P1500, is an effective test method for Systems-on-Chip (SOC) containing embedded cores. This test method is usable for all classes of digital cores and provides solutions that allow automatic identification and configuration of testability features in SOC containing embedded cores. In this moment, IEEE P1500 is restricted to...

This paper addresses testing issues associated with System-on-Chip (SoC) designs. A network-processing engine SoC was constructed using reusable Intellectual Property (IP) and a test harness based on the emerging IEEE P1500 standard. Three different test access mechanisms (TAMs) are compared on this platform – a serial threading approach analogous to the IEEE1149.1 standard, a test-rail approac...

Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemical hardness (η), Thermodynamic Properties was determi...
متن کاملTowards a standard for embedded core test: an example
Integrated circuits are increasingly designed by embedding pre-designed reusable cores. IEEE P1500 Standard for Embedded Core Test (SECT) is a standard-under-development that aims at improving ease of reuse and facilitating interoperability with respect to the test of such core-based ICs, especially if they contain cores from different sources. This paper briefly describes IEEE P1500, and illus...
