Tcl Scripting encounter

archive

Hi all,

I'm developing custom tcl scripts in Encounter for block floorplanning.
I can't execute the addStripe command with variables as "area parameters"

Example:
addStripe ....  -width $wid ......  -area{100 200 500 1000}......              is OK

but
addStripe ....    -width $wid  ...  -area{$inita $initb $initc $initd }......   doesn't work

I guess  the problem comes from the curly brackets because the $wid is applied
but the extension of the stripes is totally wrong.

Can anyone help me?
Bye

  • change you -area{..}

    to -area [list ${x1} $[y1} ${x2} $y{2}] should fix your problem.

  • Hi Giohdl,

    Not sure if the following can work, but worth trying as it illustrate an important property of TCL:

    addStripe .... -width $wid ... -area '$inita $initb $initc $initd "......

    Please refer to a TCL book on the amazing differences between {}, "" and [], if not you might run into this type of problem again!. Basically, anything inside {} are taken "as it is", so what TCL see is the number "$inita $initb $initc $initd" which of course is invalide. For LiSiang soluation, the [] force the TCL parser to do an "re-evaluation of the expression". For "", the tool do variable subsitation.

  • Hi,
    Your solutions are OK.
    This way any list of {coordinates} in
    Encounter commands can be replaced by variables.
