JTAG DEBUGGER TOOL
(JTD)
SiliconAid Solutions, Inc. Confidential
WHY JTD
• New Product Introduction/Evaluation
• Proto-typing pre-Silicon on Xilinx
Boards
• Works in concert with ATE testers
• Debug capabilities to identify internal
registers failing on TDO
• Tracks JTAG state machine on vector
per vector basis
• Fast, easy, quick way to drive and
observe standard JTAG signals
• Leverages JTV output to enhance
debugging capability
SiliconAid Solutions, Inc. Confidential
JTD Major Features
• Hardware Interface using USB 2.0
• JTAG 5 pin connector
• Can drive evaluation board, Apps board, burn in
board, ATE tester board, and more…..
• Compares expected values for TD0
• Supports run till FAIL, STEP, etc..
• Leverages patterns from JTV
• Supports external SVF patterns

SiliconAid Solutions
JTAG VERIFICATION TOOL
(JTV)
SiliconAid Solutions, Inc. Confidential
JTV - Purpose
• Verification support for JTAG providers
– Focus is chip-level verification
• Provide an efficient means to
–
–
–
–
Insure correct JTAG functionality on first-pass silicon
Deliver a verified BSDL file for customer usage
Deliver high quality production test vectors
Diagnose fab-related pad or JTAG logic yield problems
• Goal is to
– Eliminate customer BSDL and/or JTAG-related problems
