Lynsyn

The target board power supply is connected through one of the current sensors and a JTAG cable is connected to the target board.  The Lynsyn is connected to a host PC with USB and a Xilinx JTAG adapter.  The other component of the system is the analysis tool which runs on the PC providing a graphical front end to the Lynsyn PMU.

• 10kHz current sampling frequency
• 7 independent current sensors
• Non-intrusive PC sampling (JTAG) for correlating power with source code; supports ARMv7-A and ARMv8-A architectures
• Connects to host PC with USB

Lynsyn uses two INA169 current-shunt monitors from TI to measure and amplify currents across 0.1 Ohm shunt resistors connected in series with high-side current wires/PCB-tracks that drive units of interest on the EMC2-DP.  Measurements from the current-shunt monitors are sampled by a Teensy 3.6 micro-controller using 13-bits and transmitted over USB to the host computer at approximately 12K samples per second.  This rate supports application tasks up to 83 micro seconds.  Synchronization signals are sent over JTAG and LVTTL GPIO ports on the EMC2-DP to the Teensy to control measurements.
