    Library merge issue for non-symmetrical package

    jishenbiao

      Hi,friends

      I face a issue as the attached pic shows,the non-symmetircal package would not placed in postion when i make the library merge.Any idea on the issue?

      I've tried to modify the parameter of library merge interface,like orientation/dubious match/ref layer,But none of them works

      Above for the attached pic(The VPL should be slightly upside, then the place will be perfect)

          Hi Ji

           

           

               As per my understanding the pad will be aligned based on the pin no1 of Valor Library.. It can't align for all pins at a time for this type of Asymmetric pins .It will align based on the reference pin  only,If we understand well that this pacakage perfectly right you can move manually to align and run the remaining checks ,Let us wait for the experts answer...

           

           

          Thanks and Regards

            Hi,sabitha

             

            tks for your quickly response,i understand the same with you.If it's correct,the soft should develop some algorithm to avoid the poor alignment for the non-symmetrical package, unless make the user to adjust the location manually.I hope there is some good method to solve this issue instead of software revision.

              Yes Ji ,In current algorithm takes some heel distance gap and then align the pin 1 from Valor Lib with pin 1 Pad in footprint,Some components does not have the heel distance ,in that case the pin should align on edge of the pad ,if such algorithm is available in tool your issue will be resolved ... I don't get clear idea right now that how it will be implemented in tool ,If you have any idea please post it through Mentor Idea site ,I will vote to promote this.

               

              Thanks and Regards
