command to find the maximum and minimum drivestrength of a particular std cell

selvam27

Hai,

Currently I'm writing a tcl script to fix max transition violation. In this script,I used the ecoChangeCell command to upsize and downsize the cells.

I am facing a problem in this script. If I run this script, it upsize the cell upto the maximum drivestrength and after that when there is no further cells available for changing. the script exits with ERROR indication.

 Now i want the script to continue even if there is an error notification.

 Can anybody help me in this to say the tool to continue with the script even when there is error..

or 

 Is there any command to find the maximum and minimum drivestrength of a particular std cell.

Plz help me

thank you

Selva

    30. To query the max_cap for a list of cells

         set cellPtrList [dbGet -p head.allCells.name BUF*]
         foreach cellPtr $cellPtrList {puts "[dbGet $cellPtr.name] [dbFTermMaxCap [dbGet -p $cellPtr.terms.name <term>] 1]"}
