    Expedition PCB OftenRun out of Memory, A 2.0 Auto or 6.0 Auto?

    yu.yanfeng

      All Expediton pcb User,

       

      Expeditionpcb PCB have serius issues about momery footprint. Whatever which version you used, I guess It can't support  a full flow of front-to-end big design smoothly.(I have posted two posts about out of memory ).

      Jerry told us user can use ./3GB to support big design,but it may make the problem more worse sometime. I found DXF ouput  make Expeditonpcb crashed when /3GB switch use in a design. If you check the memory, you see the memory of Expeditoinpcb increase to 3GB and that make it crashed. However, the DXF ouput  is ok without using 3GB, but you can't generated the silkscreen etc.

       

      Sometimes I think Expeditonpcb just like a 2.0 Auto although having long size. To be Expeditionpcb Enterprise, It should be changed with a 6.0 strong engine.

          A good news is that 2007.7 what's new is published.

          The first is the memory footprint, here is the public data in the what's new:

          Memory (MB)
          Design Prev 2007.7 % Diff
          Customer 1 661 /489 -26.02%
          Customer 2 2532/ 1137 -55.09%
          Customer 3 "Back Plane" 1424 /1063 -25.35%
          Customer 4 “Emulation" 3596/ 1926 -46.44%
          Customer 5 1644/ 602 -63.38%
          Customer 6 "RF" 993/ 666 -32.93%
          Customer 7 "RF" 975 /659 -32.41%
          Customer 8 "Network" /1498 1449 -3.27%

          Another feaute is the plane scallops' removal

          There is another feature I have requested years, that is Modelsim's integration with Dxdesigenr. But I think it may need 24 months to make  a full Entery-Simulation-Synthesis-Board flow really work.

            It's obvious that Expeditiopcb have an inherent problem about memory leakage. I hope Expeditionpcb core team recongnize this problem. The coming-to-release 2007.7 is the only hope to me.
