An Efficient Approach to SoC Wrapper Design, TAM Configuration and Test Scheduling
Test application time and core accessibility are two major issues in System-On-Chip (SOC) testing. The test application time must be minimised, and a test access mechanism (TAM) must be developed to transport test data to and from the cores. In this paper we present an approach to design a test interface (wrapper) at core level taking into account the P1500 restrictions, and to design a TAM arc...
متن کاملEfficient Wrapper/TAM Co-Optimization for SOC Using Rectangle Packing
The testing time for a system-on-chip(SOC) largely depends on the design of test wrappers and the test access mechanism(TAM).Wrapper/TAM co-optimization is therefore necessary to minimize SOC testing time . In this paper, we propose an efficient algorithm to construct wrappers that reduce testing time for cores. We further propose a new approach for wrapper/TAM co-optimization based on two-dime...
متن کاملWrapper design for embedded core test
A wrapper is a thin shell around the core, that provides the switching between functional, and core-internal and core-external test modes. Together with a test access mechanism (TAM), the core test wrapper forms the test access infrastructure to embedded reusable cores. Various company-internal as well as industry-wide standardized but scalable wrappers have been proposed. This paper deals with...
متن کاملEfficient SoC Design with Homogeneous Processor Arrays
It is our opinion that the system-on-chip, all-in-one approach to parallel digital signal processing combining the homogeneous processor array with large amounts of data memory, will be the core of future embedded digital signal processing applications. In this paper we present two radical approaches to efficient system-on-chip (SoC) design with homogeneous processor arrays for real-time applic...
متن کاملA Reconfigurable Power-Conscious Core Wrapper and its Application to SOC Test Scheduling
This paper presents a novel reconfigurable powerconscious core test wrapper and discusses its application to optimal power-constrained SOC (system-on-chip) test scheduling. The advantage with the proposed wrapper is that at each core it allows (1) a flexible TAM (test access mechanism) bandwidths, and (2) a possibility to select the appropriate test power consumption. Our scheduling technique, ...
