Is it possible to automatically taper a track to a smaller pad? For example, how would I go about tapering a 25 mil track to a 15 mil pad?
According to Cadence engineers, neither Allegro PCB Editor nor Allegro Package Designer support tapering. Moderator
Thanks Moderator! But, coincident to your posting that reply, I spoke with the support desk at EMA-EDA and was told that the 'fillet' function could possibly do those things. Unfortunately, it requires yet another license that I may not be able to purchase. Apparently the 'fillet' function is a command found under the 'gloss' submenu. glachiew
Hmmm...simply route your cline out away from the pin as far as you want to start the taper. Then, add a shape that intersects with the cline and the pin (or new cline) with the appropriate taper. Works great.
I've tried that several times but I can only get the shape (with it's assigned net of course) to attach to either the cline or the pin but not both. It's very weird. Are you running the package that has the advanced glossing features? I'm not. Thanks for the thoughtful post.
I am running the basic level package (200 series) and it works. I am wondering: are you completely surrounding the pin? Have you sufficiently captured the cline end point? I'll try to post a sample later on today.
Where are the endpoints of the cline? Maybe that's the problem. What I'm trying to actually do is to reduce a 50 ohm trace that's fairly wide (50 mils) down to a 12 mil pad. I can get the shape to attach to the cline segment but it will not 'spoke' to the pad. I have even tried tracing the shape exactly over the pad and it still won't spoke to the pad. I must have some rule or constraint that is prohibiting the spoke to occur. Thanks again for the reply - please suggest rules to check if you can!
SOLVED! Redwire, Thanks for providing the impetus to dig deeper into this problem. Here's the solution: Right click on the mouse when drawing the shape and then set the thermal relief connects to 'full contact' and the number of pins, minimum number of connects (default is 2 and that is why it didn't work for tiny pads), etc. You must have had your defaults set up correctly. Thanks again!!
