• INVALIDQT function which sets quality invalid of outputs according to a "valid"
input. Inputs are copied to outputs. If input VALID is 0, or if its quality invalid bit is
set, all outputs invalid quality bit will be set to invalid. The timestamp of an output
will be set to the latest timestamp of INPUT and VALID inputs.
• INDCOMBSPQT combines single input signals to group signal. Single position
input is copied to value part of SP_OUT output. TIME input is copied to time part of
SP_OUT output. Quality input bits are copied to the corresponding quality part of
SP_OUT output.
• INDEXTSPQT extracts individual signals from a group signal input. Value part of
single position input is copied to SI_OUT output. Time part of single position input
is copied to TIME output. Quality bits in common part and indication part of inputs
signal is copied to the corresponding quality output.
