[PCB_FORUM] Re: [SPAM] Re: Speeding up Allegro

Well, I am at the point where I need to find which power nets, the nets
which I had NO_RAT=TRUE property on before, and it's a lot easier to see
them when you can hi-lite the rats nets. Thanx anyways.

Jim,

On power nets with lots of connections, 
Add the property NO_RAT.

Jim, 

Look for those Nets that were defined as DC nets. You may temporarily
remove this property to improve Allegro performance ... (Logic/Identify
DC nets/ ....)

[PCB_FORUM] Speeding up Allegro 


        
        




Hi folks, 
Quick question and I'm pretty sure I've seen this subject floating
around before. Allegro 15.5.1 
I'm nearing the end of routing a very large and dense design. I'm down
to cleaning up the power signals (3.3v & gnd.etc) and Allegro is
draggin' big time. What is the easiest way to reduce the time between
mouse clicks when hooking up these large pin count nets? Currently is
about 20 seconds minimum between clicks. 
Change the shapes from dynamic to static? I've turned off the on-line
DRC, but that didn't seem to help. I know it's probably something really
obvious, but my brain has turned to mush these last couple days. 
Thanx in advance.
