forcing separate clines

archive

Allegro keeps all the segments (line/arc objects) that make up a cline (path object) in nice neat tail->head order in a list.

If you lay down a trace from a pin halfway to another pin then end your Connect command that leaves a stub cline with a ratsnest line to the destination pin. If you start a new Connect command, click on the end of the stub and complete the trace and end your command you get ONE cline from pin to pin - Allegro helps you by merging the two separate clines into one.

99% of the time this is what you'd want. But of course I need that 1% :

how can one prevent this behavior? To wit: how can one force Allegro to keep clines distinct?

pinA--------------------X-----------------------pinB

instead of merging to get

pinA--------------------------------------------pinB


TIA,

  • In A16 i don't know what its called, but in A15.5.1 one could create a symbol under the logic menu (eg add a 0201). One of the clines need a new netname to aviod drc and xnet errors.
    Other methods can be used, but will create either a missing connection or drc error.
