IPextreme rolls industry’s first cJTAG IP core

Campbell, Calif. — IPextreme Inc. has announced the availability of the industry's first synthesizable IP core that implements the upcoming IEEE 1149.7 standard, which will be ratified in early 2009. The cJTAG – IEEE 1149.7 IP core is a configurable, ready-to-integrate semiconductor IP solution supporting all six classes of the IEEE 1149.7 standard.

IEEE 1149.7 will provide designers with powerful extensions to the current IEEE 1149.1 (JTAG) standard. It uses fewer pins and maintains compatibility with IEEE 1149.1-based hardware and software. “The IEEE 1149.7 test and debug technology will allow the electronics industry to extend IEEE 1149.1 capabilities while also providing increased functionality to their embedded designs,” stated Stephen Lau, emulation technology product manager, Texas Instruments (TI). TI is a key contributor to the development of the IEEE 1149.7 standard.

Key features of the cJTAG – IEEE 1149.7 IP core include:

  • Support for IEEE 1149.7 classes 0-5 (selected through hardware configuration parameter)
  • Partitioned along IEEE 1149.7-specified functional boundaries (Extended processing unit (EPU) for class 0-3 operation and advanced processing unit (APU) for class 4-5 operation, further parameterization within EPU and APU for class-specific and optional features and separate blocks for clock and reset signal conditioning.)
  • Supports all mandatory and optional scan formats: JScan0-3, SScan0-3, OScan0-7 and MScan
  • Supports all mandatory and optional commands
  • Firewall provides robust hot-connection by disabling test clock (TCK) until firewall is disabled by the debug test system (DTS)

IPextreme will be hosting a one-hour webinar in mid-September, cJTAG – IEEE 1149.7: The Next Generation in Test and Debug.

Pricing: List price is $75,000.
Availability: Available now, the cJTAG – IEEE 1149.7 product includes Verilog source code, integration testbench and tests, documentation and scripts for simulation and synthesis, with support for common EDA tools.
Product information: cJTAG – IEEE 1149.7 IP core and TI slide presentation: Squeezing the Power out of Debug and Test Interface (DTI)
