How to get back drill report in PCB layout

[karthik2dave]

I am a QC person,

I have one doubt about back drill,

we have high speed signals list,

and all signals are manually checking back drill with back drill chart.

If any report is found to take signal wise report for back drill.

kindly please inform anybody,

thanks,
karthik

Allegro PCB High-Speed Option allows
users to specify which vias on critical
high-speed signals should be back drilled
to avoid reflections. An output report—
Backdrill NC and Legend Files from
Bottom, Top, or Any Layer if backdrilling
the inner core(s) of the PCB—allows users
to send backdrilling instructions to their
PCB manufacturers.

Otherwise must be manually checked.

Hi SunnySkyguy ,

for example: net name: xxxx_1.
we assigned back-drill for this net on layout file. already we followed & checked manually back drill with generated drill chart. but may i know is this possible for report wise taken for assigned back drill signals in layout.

for allegro tools - tools -reports(any other option)

regards,
