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.
Device settings are non-volatile. Setting changes are maintained after the board is powered off.
All VADJ device settings require a power cycle to take effect.
Device Settings
| NAME | TYPE | DESCRIPTION |
|---|---|---|
| XEM7360_VADJ1_VOLTAGE | INT32 | Vadj1 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_VOLTAGE | INT32 | Vadj2 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_VOLTAGE | INT32 | Vadj3 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_MODE | INT32 | (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_STATUS | INT32 | Read-only register that contains status during runtime. [0] – POK_3V3 [1] – POK_VADJ [2] – PRSNT_M2C_L [7:3] – RESERVED |
| XEM7360_FAN_MODE | INT32 | 0=Binary mode 1=Temperature controlled mode DEFAULT: 0 |
| XEM7360_FAN_ENABLE | INT32 | In binary mode, 0=disable, 1=enable DEFAULT: 1 |
| XEM7360_FAN_TEMP_THRESHOLD FW 1.31 and before | INT32 | In 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+ | INT32 | In 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 DEFAULT: 16C |
Fan Control Device Settings
You may optionally connect a fan to JP1 (Molex 53398-0271). This connector drives the input voltage 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 fan enable based on the FPGA die temperature. See the Specifications page for more information on the available fansink unit.
Note: The board input voltage is used to power the connected fan. Make sure the input voltage is an appropriate value for the fan.
IPMI Controlled VADJ
The XEM7360 adjustable voltage rails can be configured automatically by the carrier board. This requires a compatible EEPROM to be included and programed on the carrier board. For more information see the Vadj section of the Expansion Connectors page.
