deveice parameters dont match

You might want to follow this up with Concept Engineering since SPICE Vision is their tool, but one possibility might be to use this How to call CDF callbacks procedurally from SKILL to update CDF parameters? to invoke the callbacks after the schematics have been generated. You might need to pass the ?order argument to the function to limit trigger the callbacks in the right order (usually you don't need to trigger all of the callbacks with TSMC PDKs - probably the length and finger_width (you might need to check in the CDF to see the names of those parameters rather than what the prompt is).

Thanks, Andrew, I will try it，I still have a problem which about LVS，the netlist exported from the schematic have wrong component width but right length，I want to know if this problem is caused by the above problem， thanks.

Hi, Andrew, I load the CCSinvokeCdfCallbacks.il, the internal parameters are the same as the external parameters, which is exactly the opposite of what I want. How should I deal with it? thanks

I got it，I should use the CCSinvokeCdfCallbacks(geGetEditCellView() ?callInitProc t ?useInstCDF t ?order list("w") ，then everything will return to normal， how amazing

Glad you figured it out before I had a chance to respond!

Hi，Andrew， thank you very much for helping me solve this problem first，Is there a way to help me callback all the cells at once?  I try to callback top cell only ，but it doesn't work，:(   the callbackentirelib will spend a lot of time and I dont think the result will be what I want，it is still running， lol

The CCSCdfCallbackEntireLib function in the article wasn't written by me (another colleague added it to my article), but you'll see that it suggests modifying the CCSinvokeCdfCallbacks() call to pass any other arguments you want (such as those you suggested earlier). Did you make that change?

You can't run them in parallel (SKILL is single-threaded), but I wouldn't expect it to take that long if you've just got ?order list("w") since that's only calling a single callback per instance.

Regards,

Andrew

do u means I should use CCSCdfCallbackEntireLib（“MYLIB” ？order list（“w”））just like CCSinvokeCdfCallbacks（），but it doesn't work， by the way， when I use CCSinvokeCdfCallbacks（geGetEditCellview（）？orderlist（”w“））which means I only calling a single callback， but the diode‘s area and pj will also change， I just want callback mos‘ length and width ，the diode’s parameters is right ，so I dont want to change itThe first picture is before the callback, and the second picture is after the callback

I've just looked at the CCSCdfCallbackEntireLib function in the article (which as I mentioned, I didn't write) and rewrote it so that it can now pass through all the keyword arguments to the underlying CCSinvokeCdfCallbacks function. This avoids having to take the code and modify it each time you want to pass different arguments. So now you can use it similarly to CCSinvokeCdfCallbacks and pass ?order, etc to the function.

What you specifically need in this case is the ?filterFunc argument, as that allows you to skip certain components. The diodes in the tsmcN40 library do have a "w" and "l" parameter, and you don't want to call the callbacks for these since these will compute the area and perimeter from the w and l (there's a second mode which allows area and w to be specified, but nothing that allows area and perimeter to be specified and compute the w/l - that's a little ambiguous anyway). You may need the w and l ultimately for layout purposes, but for simulation and LVS purposes area and pj are sufficient.

So download the latest CCSCdfCallbackEntireLib from the article, and also load this function:

; filtering function to return t for anything other than a PDK component
; with "dio" in the cellName
procedure(CCFfilterDiodes(cdf paramName callback)
  destructuringBind((lib @optional cell) CCSgetLibCellFromCDF(cdf) 
    unless(lib=="tsmcN40" && pcreMatchp("dio" cell)
      t
    )
  )
)

Then you can do:

CCSCdfCallbackEntireLib("mylib" ?order list("w") ?filterFunc 'CCFfilterDiodes)

or:

CCSCdfCallbackEntireLib("mylib" ?callInitProc t ?useInstCDF t ?order list("w") ?filterFunc 'CCFfilterDiodes)

whichever you found worked best.

I hope that helps!

Andrew

wow, it works perfectly, I changed “dio” to “pnp” ，it also filtered all the pnp ，whether it is dio or pnp, are there any rules for naming here? And it seems that two filterFuncs are not allowed to exist at the same time, so if I want to filter the diodes and pnps, should I callback twice? just like CCSCdfCallbackEntireLib("mylib" ?order list("w") ?filterFunc 'CCFfilterDiodes and CCSCdfCallbackEntireLib("mylib" ?order list("w") ?filterFunc 'CCFfilterpnps.

You can only have a single filtering function. Calling it twice won't do what you want. In the filtering function, you can either just use a more complicated regular expression:

    unless(lib=="tsmcN40" && pcreMatchp("dio|pnp" cell)

Or use something like this:

    unless(lib=="tsmcN40" && (pcreMatchp("dio" cell) || pcreMatchp("pnp" cell))

Hope that helps.
