can we change the routing angle using skill, currently we can change it to "off, 45, 90", is there a setting in allegro that we need to change so we can route signal using other routing angle like "10"
Hi,I don't think that is possible. axlSetLineLock only allows 45, 90 or 0 (off).What is your application? I may be able to help if I know what you are trying to do.Cheers, Dave
Dave,thanks for the reply, I'm doing layout (Allegro 15.2~15.7), currently we have some issues about the fabrication of our PCB and Differential Signals/High Speed signals (Fiber Weave Mitigation), in order minimize these effects we need to route high speed signals skewed against the fiber weave of our board, or route high speed signals with at least 5~10 degrees routing angle thanks
Hi,Well, it''s got me stumped. Ithe only way I can think of to achieve this via Skill is to re-write the route command. Probably not a very desirable solution. Another alternative may be to ask your fabricator to place your boards at an offset to the weave - or use a laminate where this effect has been reduced.Sorry I can't be of more help.Cheers, Dave
Could you route these special traces manually (using 0/45/90) then use a SKILL routine to skew them by the desired angle?But having the fabricator build the skew directly into the board sounds like the right solution - transparent to the designer and the skew applies to all traces.Keep us apprised and Good Luck,Chris Walterslocal Cadence guru()PS - anyone know of a position for a(nother) Cadence guru?
Hi,"Could you route these special traces manually (using 0/45/90) then use a SKILL routine to skew them by the desired angle?" -- i was hoping that somebody can come up on how we could materialze this idea using skill, as for the skewing the board during fabrication may have some problems, especially when the required sigals to be routed with angle are high speed signals only and we are dealing with multi layered boardsthanks
