Detailed Description

Unpack an event that has potentially more than one sample collected from a single ECOND.

See also

ECONDEventPacket for how a single sample from a single ECOND is unpacked.

Note

This unpacking is not well tested and may change depending on how the firmware/software progresses. The current draft was written using TargetFiberless::read_event as a reference. A second draft SoftWrappedECONDEventPacket was written using the HcalBackplaneZCUTarget::read_event as reference.

Member Function Documentation

from()

void pflib::packing::MultiSampleECONDEventPacket::from

(

std::span< uint32_t >

data

)

unpack the given data into this structure

The software emulation adds another header before the ECOND packet, which looks like

4b flag | 12b ECON ID | L | 3b il1a | I | 11b length

• flag is hardcoded to 0b0001 right now in software
• ECOND ID is what it was configured in the software to be
• L signals if this is the last sample (1) or not (0)
• il1a is the index of the sample relative to this event
• I signals if this is the sample of interest (1) or not (0)
• length is the total length of this link subpacket including this header word

Index	Description
0	full packet header flag mismatch
1	subsystem ID not equal to 7 (HCAL)
