JTAG Protocol Exerciser and Analyzer
JTAG Protocol Analyzer (PGY-JTAG-EX-PD) are the Protocol Analyzers with multiple features to capture and debug communication between host and design under test. PGY-JTAG-EX-PD is the leading instrument that enables the design and test engineers to test the respective JTAG designs for its specifications by configuring the PGY-JTAG-EX-PD as Master/Slave, generating JTAG traffic and decoding the JTAG protocol decode packets.

Multi-Domain View
Multidomain View provides the complete view of JTAG Protocol activity in a single GUI. Users can easily set up the analyzer to generate JTAG traffic using a GUI or script. Users can capture JTAG Protocol activity at a specific event and decode the transition on the JTAG bus. The decoded results can be viewed in the timing diagram and Protocol listing window with autocorrelation. This comprehensive view of information makes it the industry’s best, offering an easy-to-use solution to debug the JTAG protocol activity.
Exerciser
PGY-JTAG-EX-PD supports JTAG traffic generation using GUI and Script. Users can generate simple traffic generation using the GUI to test the DUT. Script-based GUI provides flexibility to emulate the complete expected traffic in the real world including error injections. In this sample script user can generate JTAG traffic as below:
Script Line #1: Set system Frequency 25MHz, Duty cycle to 50%, set TMS_Delay to 10ns, set TDI_Delay to 10 ns, and set inter message gap t0 10ns. Script Line #3: Instruction_Write
Script Line #4: Data_Write
Script Line #5: Instruction_Write
Script Line #6: Instruction_Write
Script Line #7: IR_Read
Timing Diagram and Protocol Listing View
The timing view provides the plot of CLK, TMS, TDI, and TDO signals with a bus diagram. Overlaying of Protocol bits on the digital timing waveform will help easy debugging of Protocol decoded data. Cursor and Zoom features will make it convenient to analyze Protocol in the timing diagram for any timing errors.
The protocol window provides the decoded packet information in each state and all packet details with error info in the packet. The selected frame in the Protocol listing window will be autocorrelated in the timing view to view the timing information of the protocol window and provides the decoded packet information in each state and all packet details with error info in a packet. The selected frame in the Protocol listing window will be autocorrelated in the timing view to view the timing information of the packet.
