Hi, in 16.5 is there a way to apply net attributes to a capture net and then have Allegro use that information.
What I am trying to do is in capture give certain nets a max and min length so that when the netlest is generated the info will be passed to Allegro.
Actually I would like to be able to specify a few more things like the width of the net, Min spacing between 2 nets etc ... stuff like that so the engineers can enter the info at the sechmatic level.
I looked at the net properties spreadsheet in capture and filtered it by cadence allegro but I dont see any attributes that pertain to setting min, max length of the net etc.
Not too sure if it is possible to do this or not ?, It looks like there is a way to add additional attribute fields in Capture so perhaps this might be a method to get the attributes in ?, wonder what attributes to use ?
You can set min/max length and match lenght in property editor.
You need to select Flat Nets and then locate the row/column named propagation_delay and right click - invoke UI
similarly you can do the same for relative_propagation_delay

Hello Ole, Thanks for helping.
I did a bit of digging and found a good appnote that explains how to setup constraints in capture.
