Virtuoso ADE Dynamic Parameter Clarification

jjang3

Hello everyone,

 

I just have a quick question on certain aspect of dynamic paramter on Virtuoso ADE. As you can see from the image, why does temperature reset to 27C after changing into 90C from 1900ns? 

 

 

Here is another image with temperature setting for dynamic paramter:

Thank you very much for any replies,

Sincerely,

  • Hello Andrew,

     

    Thank you very much for your reply. As you have requested:

        checklimitdest=psf 

    tran tran stop=2000n param=temp param_vec=[0n 27 1900n 90] \

    saveOptions options save=allpub 

     

     

    and I believe the subversion is:
