Member Function Documentation

clearErrorCounters()

virtual void pflib::Elinks::clearErrorCounters ( int ilink )

pure virtual

Clear the error counters for the input link.

Parameters

[in]

ilink

link index

Implemented in pflib::Capture_zcu.

getAlignPhase()

virtual int pflib::Elinks::getAlignPhase ( int ilink )

inlinevirtual

Get the alignment phase.

Reimplemented in pflib::Capture_zcu.

getStatusRaw()

virtual uint32_t pflib::Elinks::getStatusRaw ( int ilink )

pure virtual

Get the status of the input link.

Parameters

[in]

ilink

link index

Returns

encoded 4-bytes of link status

Implemented in pflib::Capture_zcu.

isActive()

bool pflib::Elinks::isActive ( int ilink ) const

inline

Check if a link is active.

Parameters

[in]

ilink

link index

Returns

true if link is active, false if invalid index or link is inactive

markActive()

void pflib::Elinks::markActive ( int ilink, bool active )

inline

Mark a specific link as active (or inactive) depending on input.

If the passed link index is outside the range of valid links, then this does nothing.

Parameters

[in]	ilink	link index
[in]	active	true if link is active

readCounters()

virtual void pflib::Elinks::readCounters ( int link, uint32_t & nonidles, uint32_t & resyncs )

inlinevirtual

Decode the counters for non-idles and resyncs from the status bytes for the input link.

Parameters

[in]	link	link index
[out]	nonidles	set to the number of non-idles
[out]	resyncs	set to the number or resyncs

resetHard()

virtual void pflib::Elinks::resetHard ( )

pure virtual

Hard reset the links.

Implemented in pflib::Capture_zcu.

scanAlign()

int pflib::Elinks::scanAlign ( int ilink, bool debug = false )

virtual

Prepare for a big spy of the link.

Modes

• 0 -> software
• 1 -> L1A
• 2 -> Non-idle

Parameters

[in]	mode	type of bigspy to setup
[in]	ilink	link index
[in]	presamples	number of presamples Read the current setup for a bigspy
[out]	mode	type of bigspy to setup
[out]	ilink	link index
[out]	presamples	number of presamples Check if the current bigspy is done

Returns

true if we are done with the bigspy Readout the bigspy and return the data

vector of 4-byte words readout from bigspy scan the input link attempting to align it

Parameters

[in]

ilink

link index

scanBitslip()

int pflib::Elinks::scanBitslip ( int ilink )

virtual

enable auto-setting of bitslip value

Parameters

[in]

ilink

link index

setAlignPhase()

virtual void pflib::Elinks::setAlignPhase ( int ilink, int iphase )

inlinevirtual

Set the l1a delay for the input link.

Parameters

[in]	ilink	link index
[in]	idelay	delay to use

Reimplemented in pflib::Capture_zcu.

setBitslip()

virtual void pflib::Elinks::setBitslip ( int ilink, int bitslip )

pure virtual

set the bitslip value for the link

Parameters

[in]	ilink	link index
[in]	bitslip	value for bitslip

Implemented in pflib::Capture_zcu.

spy()

virtual std::vector< uint32_t > pflib::Elinks::spy ( int ilink )

pure virtual

spy into the passed link

Parameters

[in]

ilink

link index

Returns

the bytes retreived from the spy

Implemented in pflib::Capture_zcu.
