lxGenFromSource related questions

Inas

Hello,

Please i want  generate a layout for schematic so o searched in the cadence layout manual and i found this command.

Then i got the schematic ID using dbOpenCellViewByType then i used the command like that

lxGenFromSource(schID "lib name (same as sch)" "layout cell name (same as sch)" "layout view name")

when i did that it gives me in the CIW error says (extra arguments or keyword missing)

Also in the rest of the fields i don't know what i have to write like the template file field also if i want to instantiate the instances there is a field in the command which is t_initCreateInstances but i don't know how to use it is that bu writing the names in the schematic or what?

Thanks a lot

BR,

Inas

  • Hi Andrew,

    I am trying the steps as indicated. But I am not getting the instances/cells and pin placed in layout.

    Note: I am using Layout GXL as I don't have licence for XL ! 

    I am running following series of commands to generate layout from schematic using generate all from source. Everything comes up True as a result in CIW but when I open the resultant layout graphically , its blank. Please let me know what I am doing wrong,

    schematic_view = dbOpenCellViewByType("mylib" "mycell" "schematic")       ........Note: I already have schematic 

    layout_view = dbOpenCellViewByType("mylib" "mycell" "layout" "maskLayout" "w")

    lxGenerateStart(schematic_view layout_view)

    lxSetNetPinSpecs(?nets lxGetPinNets() ?lpp list("M1" "Pin") ?width 0.5 ?height 0.5)

    lxGenerateFinish(schematic_view layout_view) 

     

    I will appreciate your help on this.

    Thanks,

    San
