PATH_OPTIMISATIONS Struct Reference

Struct to control which optimisations the length calculation code runs on the given path objects. More...

#include <length_delay_calculation.h>

Public Attributes
bool	OptimiseVias = false
	Optimise vias for electrical length calculations, including effective via span and trace clipping inside via pads.
bool	MergeTracks = false
	Merges all contiguous (end-to-end, same layer) tracks.
bool	OptimiseTracesInPads = false
	Optimises the electrical length of tracks within pads.
bool	InferViaInPad = false
	Determines if there is a via-in-pad present on the board but not in the item set.

Detailed Description

Struct to control which optimisations the length calculation code runs on the given path objects.

This is required as some call sites (e.g. PNS) run their own path optimisation, whereas others (e.g. Net Inspector) do not.

InferViaInPad

bool PATH_OPTIMISATIONS::InferViaInPad = false

Determines if there is a via-in-pad present on the board but not in the item set.

This condition can arise from the PNS meander placer. TODO (JJ): This can be fixed in the router

MergeTracks

bool PATH_OPTIMISATIONS::MergeTracks = false

Merges all contiguous (end-to-end, same layer) tracks.

OptimiseTracesInPads

bool PATH_OPTIMISATIONS::OptimiseTracesInPads = false

Optimises the electrical length of tracks within pads.

Note that the track must terminate at the trace anchor point to be considered for optimisation. Will require MergeTracks if used with a non-contiguous item set.
