Board revision number.
The board revision number can be read from a register. It is a four bit number that changes
when the schematic of the board is changed.
0: Experimental first board version. Labeled ”Rev. 1”
1: First commercial version. Labeled ”Rev. 2”
int board configuration
Describes the schematic configuration of the board.
The same board schematic can be populated in multiple variants. This is a four bit code that
can be read from a register.
int subversion revision
Subversion revision id of the FPGA configuration.
int chip id
16 bit factory ID of the TDC chip.
int board serial
Serial number.
With year and running number in 8.24 format. The number is identical to the one printed on
the silvery sticker on the board.
unsigned int flash serial high
high 32 bits of 64 bit manufacturer serial number of the flash chip.
unsigned int flash serial low
low 32 bits of 64 bit manufacturer serial number of the flash chip
int flash valid
If not 0 the driver found valid calibration data in the flash on the board and is using it.
3.3.3 Structure xtdc4 param info
This struct contains configuration changes provided by xtdc4 get param info().
int size
The number of bytes occupied by the structure.
int version
The version number.
double binsize Bin size (in ps) of the measured TDC data. The TDC main clock is running at
a frequency of 76.8 GHz resulting in a bin size of
≈
13 . 0208ps.
int board id
Board ID.
The board uses this ID to identify itself in the output data stream. The ID takes values between
0 and 255.
int channels
Number of channels in the current ADC mode.
Can take values 1, 2 and 4.
int channel mask
Bit assignment of each enabled input channel.
