How to change Dimensions of cells using SKILL

bappada

In 45nm technology , the default dimensions are in microns whereas in 28 nm the unit u has to be mentioned ( default is metre (!)) . While writing a skill script to port schematics from 45 to 28 , how should I take care of the dimension conversion automatically?

    Multiply the dimensions by 1e-6?

     I use the following to change the dimensions ( to accomodate for the default micrometre)  but no change is seen.  

    oldW=dbGetq(inst w)

    if( rexMatchp("[nu]"||"e-6" oldW)

    then

    dbSetq(newInst oldW w)

    else

    dbSetq(newInst strcat(oldW "u") w)

    )

    Probably the parameter is either not called "w" - maybe that is not the displayed parameter on the form? Hard to tell without seeing the data.

    Regards,

    Andrew.
