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

Thanks Gary, but that's not the issue. I just wanted to speed up the
Allegro function speed when connecting up these large pin count signals.
Disabling the dynamic shapes works great, but thanks anyways.

Jim,

 

You can easily find all nets with a common property (i.e. No Rat):

 

-          click Display -> Element, "Nets" on in Find filter

-          set Find By Name pull-down to "Property"

-          click the More button

-          click on "No_Rat=" from the section at left (it moves to the
Selected objects at right)

-          click on the Apply button

-          all of the nets with No Rat now appear in the Show Element
window

 

Good luck with it!

 

Gary

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.
