Question regarding running parametric simulations using Ocean

gurusub

 Hi all,

I have a set of design variables in my schematic. I would like to input multiple data vectors to my schematic and save the output data in Ocean

For example, If P is a set of parameters P={p1,p2,p3,p4} (p1-p4 are the design variables in the schematic). I would create a matrix of data values with different instances of P ie my data matrix would look like 

Q=[-------P1---------

     --------P2---------

    ---------P3--------]

and so on where each Pi contain (p1i, p2i,p3i,p4i). (In other words I want to use the analogus of paramset command in Spectre for ocean). I would like to simulate my circuit for these values in Q and make some measurements using Calculator function and finally store the output data in the text file. Can somebody please go through the steps in accomplishing the same?

 

Thanks,

  • Hello Andrew,

    Is there an instance when using the paramAnalysis and paramRun() functions that you may not output the indivdual 'case' data during a process simultion?  Interestingly, I output caluclated values for a t_delay parameter and also case for 2 signals which are independent of these parameters, but just not for the net which is dependent.  As if it doesn't know where to look.  

     On the theme of Parametric sims, can I ask how one prints the simulation verbose to a separate text window than the CIW?  When I say run a parametric sim using the Cadence GUI, 2 text windows automatically popup with one showing the transient/AC/...blah run data (I think this is spectre.out file), and the other captures the iterations/nesting parameters.  Yet when I write a Skill code using the paramAnalysis and  paramRun() functions, the spectre.out run data is printed in the CIW.

     

    Thanks
