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,

 

Guru

    Hi,i am a student of datamatix generation of word barcode.I am analysing an NMOS ciruit for different CORNERS and also for different parametric simulatons sweep such as temperature and body voltage. Iam doing all my simulations using analog artist GUI. I could run my NMOS circuit for different CORNERS without any parametric sweep perfectly using Analog artist. But when i try to do parametric sweep and plot the same, iam not able to view the different parametric sweep curves for different CORNERS using analog artist. In regard to this problem, i also checked a previous post concerning parametric simulation for different CORNERS using OCEAN. But i could not understand the solution posted in that post very much since i am very new to this cadence and also to OCEAN script. I would like to know if there is any solution to this problem usinganalog artist ????Or I can only run this kind of simulation using OCEAN script ???If so i would be glad if some one can help me out to do the same using an OCEAN script.Also any tips using analog artist. Thankyou very much.
