[PCB_FORUM] Re: Hi-speed routing

1 nano second is about 6 inches, as a rule of thumb.

 

If you have the stack up entered into Allegro correctly, One can hit
Display >Parasitic

On a cline and Allegro will display the delay.

 

Hope this helps

Hi,
 
I have a simple quesion.  Usually, how many nano-seconds does
1-inch-trace's propagated delay equal to?  Thank you.
