Overview

The DTS Adapter from Silvaco enables an existing IEEE 1149.1 debug test system (DTS) to take advantage of the advanced debug/test capabilities available with today’s IEEE 1149.7-enabled semiconductor devices. Offered as a standalone product or as a companion product to our Compact JTAG IP for target systems, the DTS Adapter functions as a JTAG-to-Compact JTAG translator for the debug test system (DTS), supporting debug/test of IEEE 1149.7-compliant target systems.

Easily implemented in FPGA or ASIC, the DTS Adapter provides the signal conversion and signal generation needed for existing IEEE 1149.1 (JTAG) test hardware to support IEEE 1149.7 features such as 2-pin operation, online/offline operation, Star topologies, and Scan Topology Training. With the DTS Adapter inserted into your existing IEEE 1149.1 debug/test hardware chain, you only need to upgrade your debug/test software to take full advantage of the advanced test/debug capabilities offered by IEEE 1149.7 enabled semiconductor devices.

Key features

  • IEEE 1149.1 interface to existing test/debug hardware
  • IEEE 1149.7 interface to target system(s)
  • Supports all IEEE 1149.7 scan formats
  • Supports all IEEE 1149.7 scan topologies
  • Automatic translation between IEEE 1149.1 and IEEE 1149.7 signalling for IEEE 1149.7 2-pin scan formats (MScan, OScan0-7, SScan0-3)
  • Operation is transparent to IEEE 1149.1 test hardware, except for special functions that require programming the DTS Adapter
  • Generation of IEEE 1149.7 Escape Sequences as commanded by test/debug software
  • Control of TDI and TDO for IEEE 1149.7 Scan Topology Training
  • Programmable control and data segments for IEEE 1149.7 segmented scan formats
  • Proven interoperability with IEEE 1149.7 Compact TAP from Silvaco
  • Safe connection/disconnection of target system(s)―DTS Adapter output signals are disabled (high-impedance) until enabled by DTS software
  • Easily implemented in FPGA or ASIC
  • Also useful in simulation as an IEEE 1149.7 stimulus generator

e Verification Environment for FlexRay Advanced Automotive Networks

FlexRay is the vehicle networking standard being backed by all major automotive manufacturers because it is fast and flexible while being reliable and deterministic. NXP (formerly Philips) Semiconductor is a founding member of the FlexRay Consortium and has invested heavily in a comprehensive e verification environment for FlexRay, which IPextreme is taking to market.

FlexRay - The Hardware View

FlexRay is an upcoming networking standard being established to raise the data rate, reliability, and safety of the automotive applications of today and tomorrow. Synthesizable FlexRay intellectual property (IP) is now available for those who want to integrate it into a new chip. This paper discusses what the FlexRay IP is and how to implement it; highlighting issues, considerations, and solutions for the system designer.

Metric Driven Validation, Verification and Test of Embedded Software

Today’s complexity of embedded systems is steadily increasing. The growing number of components in a system and the increased communication and synchronization of all components requires reliable verification, validation and testing of each component as well as the system as a whole. Considering today’s cost sensitivity it is important to find errors as early as possible and to increase the degree of test automation to avoid quality losses because of the increased cost pressure.
