Encounter -> OA -> Virtuoso conversion problem

baumanets

Hello.

I load to OA library LEF

cmos090 - PDK Library

   lefin -lef ../../../../common/SOC_DATA/lef/CORE90LPHVT.lef -lib
techliboa3 -techRefs cmos090
   lefin -lef ../../../../common/SOC_DATA/lef/CORE90LPHVT.lef -lib
techliboa3 -techRefs cmos090
   lefin -lef ../../../../common/SOC_DATA/lef/CORE90LPHVT.lef -lib
techliboa3 -techRefs cmos090
    lefin -lef ../../../../common/SOC_DATA/lef/CLOCK90LPHVT.lef -lib
techliboa3 -techRefs cmos090
  lefin -lef
../../../../common/SOC_DATA/lef/IO90LPHVT_1V8_50A_7M2T_soc.lef -lib
techliboa3 -techRefs cmos090
    lefin -lef
../../../../common/SOC_DATA/lef/IO90LPHVT_FILLERCUT_50A_7M2T_soc.lef
-lib techliboa3 -techRefs cmos090
  lefin -lef ../../../../common/SOC_DATA/lef/BG1V2_25_C90LP.lef -lib
techliboa3 -techRefs cmos090
   lefin -lef ../../../../common/SOC_DATA/lef/DC_LN_3V3TO1V8_100_soc.lef
-lib techliboa3 -techRefs cmos090
   lefin -lef ../../../../common/SOC_DATA/lef/PLL_PG_800x_soc.lef -lib
techliboa3 -techRefs cmos090
     lefin -lef ../../../../common/SOC_DATA/lef/PR90M7.lef -lib
techliboa3 -techRefs cmos090
      lefin -lef ../../lef/rings_BE.lef -lib techliboa3 -techRefs cmos090
   lefin -lef
../../../../common/SOC_DATA/lef/IO90LPHVT_BASIC_50A_7M2T.lef -lib
techliboa3 -techRefs cmos090

Then I save encounter project to OA database techliboa3

If I open  TOP_LEVEL cell i see Library in cells "FEOAreflib"

I want to refs via to PDK tech library and cells to STD/IO etc. library, but encounter save TOP_LEVEL with refs to  FEOAreflib

I tried to remaster cells, but it takes very long time.

How save/convert Encounter project to OA DB with refs to PDK, STD/IO?

  • Hi,

    You need first to create the library that you would like to import the LEF into.

    Please make sure at the library creation if you want to attach (only one library containing all the technology information) or to reference (if you want to use the incremental techfile capability).

    After you run the lefin command with target library the newly created one. 

    Can you please clarify what you mean by:" But I want to attach cells to my existing std, io, etc libraries." ?

    I assume that you want your design to reference the newly created library.

    In that case you need to run a remaster instances into the view.

    The best would be to save from EDI :

    Converting the EDI System Database to OpenAccess Database

    Run the following commands to convert the EDI System database to OpenAccess database:

    1. Run restoreDesign fe.enc.dat cellname
    2. Run set init_lef_file ""
    3. Run set init_oa_ref_lib " techLib"
      Other OpenAccess design reference libraries can also be appended. The first one should be the technology library.
    4. Run  set init_oa_abstract_view   "abstract"
    5. Run  set init_oa_layout_view   "layout"
    6. Run  saveDesign   -cellview   {designLib topCellName viewName}

     Thanks,

    Alex
