How to run Monte Carlo simulation in Virtuoso ADE L 6.1.3.500.5

Liangr

Dear all users and forum administrators,

I am a new IC6.1 user and I use to work on IC5.1.41 for a long time. I feel so many unknown things happened to IC6.1 and some functions are missing in the ADE.

In the new ADE 6.1.3, I could not find a way to do Corner or Monte Carlo simulation with OA design kits. I wonder if it is the problem of tool or design kits and would like to ask for help to experienced users here.

How could you run corner simulation in the new Cadence? Any hints please?

 

/Best Regards

Leon

  • Hello Andrew:

            Thanks for your quick answer.I appreciate it. After  reading the user guide, in the chapter of monte carlo  analysis, I found the sentences  of the description about stastistics for example (below), which are included in the model library. and I checked my model library (file.SCS) and I can not find these sentence and that means the model enclude the statistics variation. So I ask if these sentenses about stastistics is essential for the monte carlo simulation. 

                                                                           Thanks a lot

    example

      stastistics {

                            process{

                                                   vary  dist=

                                                  vary  dist =

                                                     .............

                                            }

                 mismatch {

                              ................

                               }

     

  • Yes, they are essential.

    With the statistics block, spectre would be unable to produce any statistical variation of any parameters, and hence there would be no point running monte carlo - it needs to know the distribution of the parameters being varied so that the variation can be meaningful.

    Regards,

    Andrew.
