Error in Netlist: Multiple pin ...

Hossein1357

Hi,

I am trying to use Bus pin capability for creating schematic symbols in OrCAD 16.6 like below picture:

and connected bus from FPGA to it in schematic like below:

However, it fails during netlist creation and I receive mass of errors like below:

I really appreciate any help in this regard,

  • You cannot use bus pins on primitive parts, see page 291 of the Capture Users Guide, cap_ug.pdf, in the doc\cap_ug directory of the installation.

  • Sorry, there is something else in mentioned page. I couldn't realize its relation to my issue. I am using OrCAD 16.6, did you reference the same revision?

    Anyway, Why can't I place bus pins in my symbol when its available in symbol editor? 

    What else can I do to get rid of placing bunch of pins instead of a bus? Is there a workaround?

    Thanks,

    Hossein

  • 16.6 version Page 291 has a discussion on Bus Connectivity: "You can use bus pins...." then: "Bus pins will only work with the VHDL netlist format. No other netlist format understands them.
    Do not use bus pins in the following situations:
    Pins on primitive parts.
    Any design that you intend to use with PCB Editor." There is no workaround, part pins need to be scalar, individual pins.

  • Thank you for the answer. Yes, It seems so.

    However, in my document it is on P245 not P291!.

    I found it by searching the exact phrase you had written. Is there any new update for document? I would appreciate if you can give me a link.

    Thanks again,

    Hossein
