16.2

  • Finding Router Efficiency (Trace Utilization)
    Hi All, I am new to Cadence Allegro. I need to calculate the trace utilization for a specific board. Is there a way in PCB editor (16.2) to do calculate this automatically? I have heard that the trace utilization (router efficiency) is roughly around 30% but I want to calculate the exact number for the...

  • DXF import in Allegro (argh!)
    I'm desparately trying to import a vector based logo into a Orcad PCB 16.2. However, this for some reason suddenly seem impossible: If I try to import DXF I never seem to be able to "view selected layers" (and thus never import anything). The dialogue does however show me DXF layer names...

  • Re: No Board outline when artwork is made
    It's late and I'm totally busted - but my 16.2 also seems to ignore the "undefined line width setting" for the outline... Showing the films looks fine (BoardGeometry/Outline layer is included in films)! So I thought I could just change the outline in the BoardGeometry/Outline layer...

  • Re: Plane creation in Orcad Layout V16.5 - adding board edge clearing
    I'm obviously not working with Allegro/Orcad PCB (I think Layout is stone dead?) often enough. But right now I'm trying to change an old board to include some clearing between etch and board outline. (Highly related to this pos, so I hope my intrusion will be forgiven ;-). It should be easy ...

  • Back annotate / Netlist Update
    I'm new to Orcad so bear with me. I've been using Orcad 16.2 Capture and Layout. The schematic was created in capture and then the board was laid out. In the board, I changed some parts (both name and footprint) as well as some netlists. How do I update the schematic to reflect this? I tried...
