Customize PDK library without changing it.

nosaj

Hi all,


I'm looking for a way to change the CDF default value that doesn't require user interaction and changes to the actual PDK library.

e.g.

By default, pmos A=1, and CDF value of pmos's x, y, z  depends on callback of A.

Normally when the user instantiate pmos, they will change A=2, and subsequently updating x, y, z.

What I want : When user instantiates the pmos, CDF is already set to A=2 and x, y, z already update accordingly and automatically

How can this be achieved?

 Thanks in advance.

  • Thanks Lawernce.

    I've already tried changing the effective CDF of A = 2 as a test.  But when I instantiate the instance A is = 2, x, y, z don't get updated.

    I was thinking if there's a way to update the effective CDF *AND* triggering the callback of "A" automatically, this might work.

    This this what you're describing?

    But I'm not sure how to

    1. load the code only after libInit.il is load (appending code to the end of libInit.il would mean changing the PDK) and

    2. how to change the effective CDF and trigger the callback automatically without user's interaction...
