clock tree synthesis

I'm using the old CTS. What I found in the manual related to the "Macro delay" is this command:

Macromodel pin lefPinName maxRiseDelay minRiseDelay maxFallDelay minFallDelay inputCap

please confirm if this is what you mean. I need a delay of 0.2 ns in a special net so here is what I do:

I create a scheduling file and add the following command to it (I'm not sure I'm setting the values correctly. Should I set the fall delays equal to the rise delays ?.....I need the whole clock to be delayed with ~0.2 ns)

Macromodel clk_i__L5_N837 CK 0.3n 0.2n 0 0 0.9497f

and then I set the scheduling file in the configuration file of the tool.

and I add these two commands to my script file: 

setOptMode -usefulSkew true
optDesign -preCTS

Is what I'm doing correct ?

Here's a sample command from an old script:

MacroModel pin macro1/clk 300ps 300ps 300ps 300p 35fF

I wouldn't put 0 for the fall delays. Use the same numbers as the rise.
