UART Protocol Exerciser and Analyzer

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

UART Protocol Exerciser and Analyzer

UART stands for Universal Asynchronous Receiver Transmitter. A UART’s main purpose is to transmit and receive serial data. PGY-UART-EX-PD is the leading instrument that enables the design and test engineers to test the UART designs for their specifications. Generating UART traffic with custom traffic capability and decoding UART Protocol packets.

he product features are as follows:

  • Supports custom UART traffic generation
  • Simultaneously generate UART traffic and Protocol decode of the bus
  • Variable UART baud rates
  • Continuous streaming of protocol data to the host computer to provide a large buffer
  • A timing diagram of Protocol decoded bus
  • Listing view of Protocol activity
  • Error Analysis in Protocol Decode
  • Ability to write exerciser script to combine multiple data frame generation at different data speeds
  • USB 2.0/3.0 host computer interface
  • API support for automation in Python or C++

Multi-Domain view

Multi-domain View provides the complete view of UART Protocol activity insingle GUI. Users can easily set up the analyzer to generate UART traffic using a GUI or script. Users can capture Protocol activity at a specific event and decode the transition on the UART line. 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 UART protocol activity.


PGYUARTEXPD supports UART 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 UART traffic as below:

Timing Diagram and Protocol Listing View

The timing view provides the plot of TX 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 packet.

Setup View

Users can configure the PGY-UART-EX-PD for different baud rates, for different configurations of Data width and Stop bits. Users can also choose whether the parity is odd or even depending on the data type being used and also select the data shift type.
