    Encounter OpenAcces: problems with exporting design Reply

    Hi!

    I have the following problem: I'm running an Encounter session in a directory called "Encounter". In this directory I put:

    a) pixel.conf file

    b) floorplan.fp files

    c) pixel_synt.v (verilog netlist)

    d) pixel.sdf file

    e) lib.defs file: in this file I have the paths pointing to many libraries, in particular a library called "Francesco_1" (this is a library I've previosuly created in Virtuoso. In this library I have the schematic fomr which the pixel_synt.v has been generated).

     

    Now, I import my design using pixel.conf and I do P&R.  During the design flow I save many times using Save As --> SoCE.

     

    At the end, I try to export the design in my Virtuoso library: I go on Save As --> OA; here I can select my library (Francesco_1) and save the design.

    Now, the problem is that this process dosen't always work: a couple of times I can obtain (in Virtuoso) a correct layout, but many other times it happens that in Virtuoso only few nets are imported (it is not layer dependant: I mean, I can have 10 nets of layer M3, but I should see 30 nets, so the problem is not with a particular layer. It just happens that some random nets are not exported).

     I tried to repeat this process many times, changing library and so on, but the problem seems very random (once I tried to export the layout in an empty directory, so without the original schematic, and it worked...next time I tried to do the same, and it didn't work).

     

    Suggestions?

     

    Thanks for help

    Francesco.
