Modify a parameter value in an input.scs file

insaf
Hi all,
 
I want to modify a parameter value in an input.scs file directly with a command function which allows to overwrite into this file and change the value of Vdd for exemple without crushing the rest of the file.
-----------------------------------------------------------------------------------------------------------------
 simulator lang=spectre
 global 0
 parameters Vdd=2.8 SwPresto=1 Vb=0 Vg=1.664 gateresglobal=0 \
 lsimpackaging=0 matching=1 swjunexpglobal=1 swleakglobal=1 swdg=0 \
 mimglobal=1 globaldtaplus=0 hdiprocessssmc=0 "
------------------------------------------------------------------------------------------------------------------
Is there any Skill command that allows to do this?      
Thanks in advance.
 
Best Regards,
Insaf

    Hi Insaf,

    I think that the way to go about this is to use the OCEAN command desVar() to change the value of a design variable.  You can then also run or re-run a simulation from OCEAN commands.  OCEAN is the SKILL scripting interface to the Analog Design Environment (ADE).

    Hope this helps to answer your question.

    Regards,

    Lawrence.

    Hi Lawrence,

    Thanks Lawrence for your response.

    but, all i need is to modify systematically the parameters value in this file with a routine by incrementing Vg and Vdd and load it in each time to be used in a specific application without running any simulation.

    I hope that my explanation was clear for you so that you can help me.

    thanks a lot. 

     Best Regards,

    Hi Lawrence,

    Thank you again for your interest. I was actually looking for the following command to modify a parameter value in my file. 

    sh(sprintf( nil " sed -i s/Vdd=2.8/Vdd=newValue/g $filename " )) 

    Best Regards,

    Insaf
