Device Settings

The XEM7360 supports the FrontPanel Device Settings in the table below, accessible from the FrontPanel Application as well as the Device Settings API.

Note: All VADJ device settings require a power cycle to take effect.

Fan Control Device Settings

You may optionally connect a fan to JP1 (Molex 53398-0271). This connector drives a signal to the fan according to the Device Settings. For most applications, we recommend binary operating mode and enabling the fan at all times. You may optionally configure a temperature control whereby the output is switched based on the measured temperature of the FPGA die.

NAMETYPEDESCRIPTION
XEM7360_VADJ1_VOLTAGEINT32Vadj1 output voltage specified in 10’s of mV. For example, “330” would set Vadj1 = 3.3v.

Valid settings are 330, 250, 180, 150, 125, 120.
Rev EXX valid settings are 330, 300, 280, 260, 250, 220, 180, 150, 130, 125, 120.

DEFAULT: 120
XEM7360_VADJ2_VOLTAGEINT32Vadj2 output voltage specified in 10’s of mV. For example, “330” would set Vadj2 = 3.3v.

Valid settings are 330, 250, 180, 150, 125, 120.
Rev EXX valid settings are 330, 300, 280, 260, 250, 220, 180, 150, 130, 125, 120.

DEFAULT: 120
XEM7360_VADJ3_VOLTAGEINT32Vadj3 output voltage specified in 10’s of mV. For example, “180” would set Vadj3 = 1.8v. Vadj3 connects to a High Performance bank and supports a maximum of 1.8v.

Valid settings are 180, 150, 125, 120.
Rev EXX valid settings are 180, 150, 130, 125, 120.

DEFAULT: 120
XEM7360_VADJ_MODEINT32(1:0) : Vadj1 mode
(3:2) : Vadj2 mode
(5:4) : Vadj3 mode
(6) : Reserved
(7) : Vadj output enable: 0=disable, 1=enable, Applies to ALL Vadj. 

Vadj Modes:

0=Minimum setting (1.2V)
1=IPMI setting only.  If a valid IPMI EEPROM is not found, Vadj is set to its minimum setting (1.2V).
2=IPMI with fallback.  If a valid IPMI EEPROM is not found, Vadj is set according to XEM7360_VADJx_VOLTAGE.
3=IPMI ignore. IPMI settings are ignored and Vadj is set according to XEM7360_VADJx_VOLTAGE.

DEFAULT: 170 (0xAA) – Each Vadj at mode 2 with output enabled.
XEM7360_STATUSINT32Read-only register that contains status during runtime.

XEM7360_FAN_TEMP_THRESHOLD
FW 1.31 and before
INT32In temperature controlled mode, the number here represents the lower threshold (in degrees Celsius) for temperature-dependent operation.

At THRESH, fan control PWM=0%.

At THRESH+16C, fan control PWM=50%.

At THRESH+32C, fan control PWM=100%.
XEM7360_FAN_TEMP_THRESHOLD
FW 1.42+
INT32In temperature controlled mode, the number here represents the threshold (in degrees Celsius) for fan enable.

At THRESH, fan is enabled

At THRESH-10C, fan is disabled
