Are there any SKILL functions for Auto routing in Non-graphical mode ?

I thought this had come up before and saw that you'd asked the same question a while back: http://community.cadence.com/cadence_technology_forums/f/48/t/33777

I answer a (somewhat) similar question recently too: http://community.cadence.com/cadence_technology_forums/f/48/p/35110/1345210#1345210

If you have access to the router, you could select multiple nets and then call lxSelectedRoute() or lxSelectedRouteNet() if you have shapes selected instead. The code I mention above does them one at a time, but better would be to select them all and call the function.

I'm not sure if there is a function to call the router without a form (probably should be, but from a quick check I couldn't find it) for all nets.

This is definitely helpful information . I appreciate it..

Thanks

Hi Andrew,

My question is similar to what was asked before. I am looking for a solution to do the routing part in non-interactive mode.

Here is my piece of code. 

procedure(CreateLayoutXL(libName cellName)

;; Generate from Source and Place as in Schematic

newCvId = lxGenFromSource(
CvId = dbOpenCellViewByType(libName cellName "schematic" "" "r")
?layLibName libName
?layCellName cellName
?layViewName "layout"
?initCreatePins t
?initCreateInstances t
?initCreateBoundary t
?initDoStacking t
?initDoFolding t
?initCreateMTM nil
?initGlobalNetPins t
?initCreatePadPins t
?initCreateSnapBoundary t
;?lxPositionMinSep n_lxPositionMinSep
?lxGenerateInBoundary t
?extractAfterGenerateAll t
?extractSchematic t
?ignoreSchematicCheck t
)

;;Auto-Routing section (source: Andrew)
cv = dbOpenCellViewByType(libName cellName "schematic" "" "r")
netName=cv~>nets~>name
foreach(net netName
geDeselectAll()
hsmSelect(?type 'net ?name net)
lxSelectedRoute(t)
)

printf("Lib Name: %s Cell Name: %s\n" libName cellName)
dbSave(newCvId)
dbClose(newCvId)
) ;end procedure CreateLayoutXL

The first part of the code (Generate from Source and Place as in Schematic) works in non-interactive mode. I would like to do routing part in non-interactive mode too. Is that possible? If so, could you specify the skill function?

Thanks,

Dinesh

Dinesh,

I'm not aware of a way of doing this (other than doing it graphically using geOpen or deOpen and then running in -nograph mode with a replay file). It may be possible, but I couldn't find it (from a  fairly quick check, so I may be wrong).

I would suggest you contact customer support where we can spend a bit more time on seeing if there's an answer or whether an enhancement request is needed.

Regards,

Andrew.

Andrew,

Thank you for the feedback. I logged in a service request regarding the same on Friday.
