int adc rpm
Speed of the ADC fan. Reports 0 if no fan is present.
int fpga rpm
Speed of the FPGA fan. Reports 0 if no fan is present.
int alerts
Alert bits from the system monitor.
Bit 0 : FPGA temperature alert (> 85
◦
C)
Bit 1 : Internal FPGA voltage out of range (< 1.01V or > 1.08V )
Bit 2 : FPGA auxiliary voltage out of range. (< 2.375V or > 2.625V )

int pcie
link width
Number of PCIe lanes that the card uses. Should be 4 for Ndigo5G.
int pcie max payload
Maximum size in bytes for one PCIe transaction, depends on system configuration.
3.3.5 Structure ndigo slow info
int size
The number of bytes occupied by the structure.
int version
A version number that is increased when the definition of the structure is changed. The incre-
ment can be larger than one to match driver version numbers or similar. Set to 0 for all versions
up to first release.

C.
3.4 Configuration
The device is configured with a configuration structure. The user should first obtain a structure
that contains the default settings of the device read from an on board ROM , than modify the
structure as needed for the user application and use the result to configure the device.
