Elgris Technologies (www.elgris.com) has ways to export Telesis netlist (including DEVICE files) from DxDesigner, PADS Powerlogic, Altium, etc.
In reply to luvishis:
I can't speak for the other front end schematic packages but I know that DxDesigner (Viewdraw) has the ability to export a Telesis Netlist with matching Device Files which can then be loaded into Allegro. It has been a while since I managed the licenses for DxDesigner but from what I remember there was a minimum charge for the PCB Interfaces license in order to export a 3rd party netlist from the schematic.
Hope this helps,Mike Catrambone
In reply to mcatramb91:
This is correct. DxDesigner(Viewdraw) does have an ability to export Telesis netlist. However, the price for this interface was raised significantly and it is several thousand dollars now. PADS Powerlogic or Altium Designer don't have a way to export to Telesis.
This is why Elgris developed the solution to export Telesis netlist from several schematic front-ends.
OrCAD Capture can generate a telesis netlist. When you make a package symbol you can generate a generic device file in PCB designer. These 2 in combination will allow you to import Allegro. You can also export device files from a completed board. Since Capture and HDL are intergrated with Allegro these files are generally not used much anymore. As Mike noted there is detailed information in the PCB Editor user guide.
