The Xilinx
®
System Monitor (SYSMON) technology enables monitoring the physical environment
via on-chip power supply, temperature sensors, and external analog inputs. SYSMON is a key
part of the power management infrastructure for the board, providing telemetry informaon for
the supplies for the Xilinx device and the various other on-board supplies.
The analog mixed signal (AMS) block present in Xilinx 7 series FPGAs is called XADC (includes
SYSMON funcon). Apart from the SYSMON funcon, the ADCs provide a general-purpose,
high-precision analog interface for a range of applicaons. The following gure shows the block
diagram of the single XADC block available in the Spartan-7 family. The interface can be JTAG,
DRP, and AXI to the XADC/SYSMON block.
See the 7 Series FPGAs and Zynq-7000 SoC XADC Dual 12-Bit 1 MSPS Analog-to-Digital Converter
User Guide (UG480) for details on the capabilies of the analog front end.
