The XEM7350 supports the FrontPanel Device Settings in the table below, accessible from the FrontPanel Application as well as the Device Settings API.
FMC Device Settings
The XEM7350 has a single FMC port which is configured using the FMC1_* settings. These settings are used to control FMC Vadj behavior as well as control and query FMC connector signals.
FMC1_CONTROL and FMC1_STATUS are volatile device settings that are never stored to nor retrieved from non-volatile storage on the device. Instead, they control and query signals on the connector in real time.
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.
|FMC1_VADJ_VOLTAGE||INT32||Vadj output voltage specified in 10’s of mV. For example, “330” would set Vadj = 3.3v.|
Valid settings are 330, 250, 180, 150, 125, 120, 0.
Rev FXX valid settings are 330, 300, 280, 260, 250, 220, 180, 150, 130, 125, 120, 0.
|FMC1_VADJ_ENABLE||INT32||Vadj output enable: 0=disable, 1=enable|
|FMC1_VADJ_MODE||INT32||Vadj setting mode|
1=IPMI setting only. If a valid IPMI EEPROM is not found, Vadj is disabled.
2=IPMI with fallback. If a valid IPMI EEPROM is not found, Vadj is set according to FMC1_VADJ_VOLTAGE.
3=IPMI ignore. IPMI settings are ignored and Vadj is set according to FMC1_VADJ_VOLTAGE.
|FMC1_CONTROL||INT32||Write-only register that controls FMC1 signals during runtime.|
 – TRST_L
|FMC1_STATUS||INT32||Read-only register that contains the FMC1 signal status during runtime.|
 – PRSNT_M2C_L
 – CLKDIR – PG_M2C
 – POK_3P3
 – POK_VADJ
[6:5] – GA[0:1]
1=Temperature controlled mode
|XEM7350_FAN_ENABLE||INT32||In binary mode, 0=disable, 1=enable|
FW 1.31 and before
|INT32||In temperature slope 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%.
|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
