Re: Library Managment in Allegro V16.5 & Browsing Packaged Symbols.
I hear you......I was just ranting to my boss this morning about the pathetic (lack of) interface to skill files. Cadence really should pay more attention to some of these "minor" problems. But nooooo, what do they do? They screw around with the route and slide command instead, to the point that it sucks!!!! Now I can't get a ...

Re: Library Managment in Allegro V16.5 & Browsing Packaged Symbols.
You can go to SETUP > USER PREFERENCES > PATHS > LIBRARY > PSMPATH > click on the value box to the right of the PSMPATH. Check the expand box in the popup. Double click the pathname.

Re: Routing differential pair with same length

Re: Routing differential pair with same length
The "Electrical constraint set>static phase tolerance" in the constraint manager is what controls this. Click on the button that says"ns" and select "mils". Then type in the tolerance you would like. I usually type in 10 mils. Remember that "10 mils" will give you +/- 10 mils window. So any given diff ...

Re: Skill files location
Ok, so I was able to find enough info on COS to get the skill files to load. According to the doc I read, allegro.ilinit should be in the pcbenv folder. The path to the skill files MUST use the /. Here is the contents of the allegro.ilinit file:setSkillPath(buildString(append1(getSkillPath() ...
