This integrated solution for thermal management and the measurement of on-chip power supply voltages simplifies system management and diagnostics and can be used to minimize power consumption. System Monitor also enables debug and testing during hardware development and manufacturing. User defined alarms warn of critical temperature or power supply conditions.

System Monitor is fully accessible from fabric or JTAG TAP, and functional on power up before FPGA configuration and during power down (via JTAG TAP only). The fully specified general purpose analogue-to-digital converter (ADC) can digitize on-chip analog sensor output and monitor up to 17 external analog inputs for environmental data. Automatic calibration and self check features ensure accurate, reliable measurements over a temperature range of -40°C to +125°C.
