Context

The IEEE 1687-2014 (IJTAG) standard was developed to answer the new testing needs of complex multi-IP instruments like Systems-on-Chip (SOC). It normalizes access to embedded IPs and instruments and the way IPs interact. IEEE 1687-2014 allows both interoperability of solutions and functional reuse of embedded resources.

Technology

The MAST software environment is the first to propose a fully functional approach to IEEE 1687-2014. It allows definition and execution of system and component test throughout their lifetime, from design to final deployment and usage.
MAST is composed by a library and a PDL API for C or C++. MAST allows dynamic execution of test programs without offline vector generation. This is possible by combining three elements:

  • A model of the System Under Test (SUT)
  • An API allowing SUT access following 1687 semantics
  • A Manager handling model management, API calls and access to the physical SUTMAST supports several physical interfaces for chip access, like for instance JTAG, I2C or SPI. It also allows system test during simulation.

Advantages

  • Time gain for both generation and application of test in chips or complex systems (SoCs, etc..)
  • Massive parallel execution of test algorithms
  • Algorithms written in C or C++ rather than TCL
  • Automated chip configuration for instrument access
  • Porting of test application throughout system life cycle
  • Native support for JTAG, I2C or SPI, extensible to arbitrary interfaces
  • Boosts confidentiality of tested elements or systems.

State of progress

The software works under Linux, Windows and Embedded Linux using exclusively standard libraries. Given the youth of the 1687 standard, validation and testing have been done on a representative set of examples in emulation, simulation and prototyping.

Applications

For actors in all fields of electronics and microelectronics (IP Provider, Design House, Fabless, TestHouse, Component providers, EDA software editors, ….):

  • Test of components, SoCs and electronic boards (Debug, DfT, Yield Analysis..)
  • System Analysis and Validation (Silicon and In-Field Debug)
  • Digital and Mixed-Signal Embedded instrumentation.
