Many IC companies use Orcad for schematics and Pads or Allegro for layout. Many of them have them available for download. Allegro useds Orcad (Orcad Capture)(Design Entry CIS) for schematics.
Yes for netlist from Orcad its Netlist, other, orPadspcb.dll But I use Chuck T's Orcad-to-Pads netlister, PowerNET.exe which must be renamed orPowerNET.exe
It is a much better solution. But wait there is more! In Orcad export to 16.2 format, in Pads Logic, import, tools, Pads Layout. and now you are cross probing which makes part placement a wiz.
