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 Inas,

    Look in the documentation for lxSetNetPinSpecs. Something like this:

    leSetEnv("createPinLabels" t) ; may need other cdsenv to control layers and heights for labels
    lxGenerateStart(schCv layCv)
    lxSetNetPinSpecs(?nets lxGetPinNets() ?lpp list("M1" "drawing") ?width 0.5 ?height 0.5)
    lxGenerateFinish(schCv layCv)

    this is a different API from using lxGenFromSource but achieves the same idea but with a bit more control.

    Regards,

    Andrew.
