Detailed Description
System Monitor Header (J35)
Figure 1-30 shows the pinout for the System Monitor 12-pin header. The header provides user access to the analog power supply (AVdd) and the 1.25V reference shown in Figure 1-29, page 68. Access to the FPGA thermal diode and dedicated analog input channel (Vp/Vn) is also provided on this header. The header can be used to connect user specific analog signals and sensors to the system monitor.
The kelvin points for a 5 milliohm current sensing shunt in the FPGA 1V Vccint core supply are also available on this header. By connecting header pins 9 to 11 and 10 to 12 using
jumpers, the system monitor can be used to monitor the FPGA core current and power consumption. This can be used to collect useful power information about a particular design or implementation.
