    Hi All,
    I have been using Orcad last five years for schematic and pcb design.
    I think Orcad has bugs, it hasn't got useful tools specially at PCB
    design. So I want to use a different eda tool and we plan to use
    PCAD-2006. Our designs have got high speed tools and lines, BGA packs,
    a lot of SMD device, etc.
    Anybody have recommend about pcad or others (Pads, Allegro, Altium

    I know Pads, Orcad, Eagle, old Tango and at beginner level Altium and
    Protel (and a little PCAD). From the perspective of schematic capture,
    Orcad is my favourite. From the BGA editing and library manipulation
    perspective, Pads is the first one. From the autorouter perspective I
    can't say anything. All are nasty.
    Some specialists say that Altium Designer is the best for huge
    designs, but in my evaluation process I found Altium difficult for
    use, with a lot of documentation splitted in too many documents. Pads
    is difficult too, at least aparently has less documentation and better
    Any program will be, imagine you need a longer learning curve than
    you've spend for Orcad, so choose well.

    Well, if you use the whole package (Orcad + Allegro + SpectraQuest) you
    *do* have a high speed design package.

    I am not affiliated with them, but I have done successful high speed
    design in that environment (think thousands of 5Gb/s links).

    Most current tools support such things, but expect to pay through the
    nose for them.

    I think so Orcad is very good about schematic capture but PCB design
    is very bad.
    Allegro and Orcad interfaces are same? Can we say If you use Orcad you
    can use Allegro easily?
  5. P-CAD is effectively being phased out in favour of Altium Designer,
    (Altium own P-CAD)
    Read this:

    Altium Designer is the only "unified" product available, which means
    it has integrated support for FPGA's, embedded processing, and signal

    I would strongly recommend Altium Designer instead of P-CAD.

  6. : perspective, Pads is the first one. From the autorouter perspective I
    : can't say anything. All are nasty.

    In the old days when Pads was bundled with the Specctra router, I recall
    feeling the relief that finally there is an autorouter capable to perform
    a decent routing job, after tweaking its options a bit. The router in the
    current Pads versions is as bad as any other I've seen.

    Does anybody else share this appreciation to the Specctra, or is it
    just that the time has gilded my memories?

    A while back, I spent some time evaluating both Allegro and Altium
    designer as a replacement for the discontinued P-CAD that I have been
    using. Of the two, I felt that the Allegro was a lot more focused on
    designing boards and Altium Designer was trying to follow the Eclipse
    concept of one unified IDE. Company management decided that they didn't
    want to spend the money to upgrade at the time, but given the choice, I
    would have chosen the Allegro hands down.

    The integrated tool suite from Cadence (not available directly any more)
    includes OrCad and Allegro - they are both owned by Cadence so netlists
    etc. transfer easily.
