VCAR ignoring non top-level keepouts

stuso

 Hi there,

i'm finding that VCAR is ignoring keepouts that are not drawn at the top level. For example a keepout one level df hierarchy down will be ignored. I do have  Conductor depth set to 32 in the export to router form. I'm not sure if this is something to do with the syntax of my rules (which i've included below). 

Cadence version: IC5141_USR6

VCAR version: ICC11241_lnx86 (11.2.41.06)

Thanks

Stu

MY KEEPOUT RULES:

 iccKeepouts = list(
    list( nil list(
        list(
            "=>" list('("prBoundary" "boundary"))
            '("M2" "drawing") "routing" t
        )
        list(
            "=>" list('("prBoundary" "boundary"))
            '("M3" "drawing") "routing" t
        )
        list(
            "=>" list('("prBoundary" "boundary"))
            '("VIA2" "drawing") "routing" t
        )
    )   32)
)

  • Hi there, i have a solution.

    I restarted cadence AND completely deleted everyting in my VCAR run directory. The keepouts are now being obeyed.

    I didn't explain initially but my keepouts were working OK last week, with the same rules file. However, i had been running different rules files and messing around in the same directory. Perhaps VCAR was picking up information/settings from the run directory.

    Thanks
