Altium Auto Routing Issue

dcciie251

 Hi,
Need Altium expert help on below issue.

Using “Auto route” in Altium, routed report shown as below:
Routing finished with 3 contentions(s). Failed to complete 1 connection(s) in 6 Minutes 52 Seconds

Physically view can see few un-route nets, but “Design Rule Check” report showing “Un-Routed Net Constraint” = 0

Anyone can commend how accurate Altium “Design Rule Check” report?


What is the recommending action for further step to resolve un-routed net?

I tried run again auto route (All) then with below result:
Routing finished with 0 contentions(s). Failed to complete 0 connection(s) in 2 Minutes 22 Seconds
But physically view can see more un-routed net and un-connected via!!! WHY?


Anyone can recommend any other powerful auto routing tool that able to route Altium PCB file format (.PcbDoc), after routed then can import back to Altium for further process?


Thanks.

  •  Altium can export a Specctra netlist which is for a Cadence product.  You can autoroute in Cadence and then read in the routed board back in to Altium.

    But if you have Specctra you probably have Allegro which begs the question "why Altium" and why post Altium questions on the Cadence user forum? :)

  •  I fear you are spending time trying to get Specctra to overcome a possible translation issue and autoroute all connections 100%

    Not a good use of time. 

    As someone who has spent weeks trying to tackle 2,000+ unroutes on a board with 28,000 connections...Route that last connection by hand in Altium and ship it.  If Altium says it has Zero connections...  Its ready to be shipped.

     "Anyone can recommend any other powerful auto routing tool that able to route Altium PCB file format (.PcbDoc), after routed then can import back to Altium for further process?"

    Not for Altium.  If you switch to Expedition, their route technology, purchased from Veribest, does improve routing completion.

    But, their signal integrity and constrained net support is not nearly as powerful as Cadence.  If the board isn't going to work, why bother?

    Which was from Intergraph which purchased it from Daisy? IIRC? :)  I guess you go way back (too) :)

  • To continue the family tree, Daisy got it from their merger with Cadnetix.

  •  And then somewhere the Telesis (Telesys?) netlist format was created... before my time in pcb layout.
