LVDS routing in Layout Plus or Specctra

lvds layout

Friends:

Do someone knows what can I do an automatic differential pair layout in Specctra or Layout Plus?

In Orcad Capture, I can set the differential pair, but I can't play it on Layout.

Some tutorial???

Thanks a lot

differentail pair in layout plus

Hi,

I am sorry but I am unable to answer your question but since you mentioned that you are able to set up a differential layout using orcad I was wondering if you could be kind enough to help me out with that! If you could tell me what components you used to set up the differential pair and how you went about simulating it then that would be super!!!!

thanks

specctra net pair

Hello,

differentail pair routing can be achieved by defining net pairs either interactive or by a *.do file. Additional parameters as distance are assignable. Some layout tools are able to export differential pair property in their Specctra interface, allowing assignment in layout design rules. Specctra requires ROUTE FST license for differential pair routing.

Hi,
You cannot use differential pairs in Layout. You can use them only in Capture. The netlist dosn't carry to Layout the information needed. Probably it is possible to work with differntial pairs in Allegro.
