Physical constraint error

Hi everyone,

I imported a .brd file from the Allegro PCB Editor to specctra for autorouting.I set the electrical and physical and spacing rules for the all the nets in the Allegro PCB Editor Constraint Manager but when i exported that to the Specctra Autooruter the spacing rules are not visible.Moreover the nets are routing without these spacing rules(Wire to wire spacing,wire to via spacing etc).But these are following the electrical and physical rules.Can anyone please give a solution to route the nets with the spacing constraints also?Is there any command to autoroute the nets including the spacing rules?

Thanks in advance

Hi BillZ,
I usually launch the router from PCB Editor.All the rules except the spacing rules for some nets are not loading.Some of the nets have the spacing rules also for example the wire to wire clearance etc.How can i overcome this situation?
Thanx
Neha.
