Lynsyn Lite
Lynsyn Lite (see the figure above) is an enhanced and cost optimised version of Lynsyn Original. It is designed to measure power for up to 3 different components at the same time, in addition to sample the program counters (PC) of the board under investigation.
-
3 power sensors, each consisting of an independent current and voltage sensor
-
Correlates power measurements with source code by sampling program counters over JTAG
-
JTAG sampling supports ARM Cortex A cores (currently A9, A53 and A57)
-
Up to 10kHz sampling frequency
-
Can be used as a generic remotely controlled current/voltage meter
-
Can be used as a generic USB JTAG programmer with Xilinx Vivado tools.
-
Includes open source software that samples and visualises the results
The PMU is controlled using SW running on a host PC.
