Callback procedure doesn't work when I change the cellname.

TiNat
Hello. Who can help me. I create library with low voltage and
high voltage mos. The minimum length of channel for low voltage mos is 0.35u,
for high voltage mos is 3u.
I set length 1u for low vol. mos, and when I change the cellname on nmos_hv the length 
1u is remain, although I'm using callback procedure. This procedure works only when I change any
value of whatever parameter, but doesn't work when I change cellname.
Such problem is present in NCSU 1.5.1 but doesn't present in others PDK.
What I must to do for deciding this problem?

Best Regards.

  • Callbacks are never fired on the cellName changing (there's a CCR for that). Some PDKs workaround this by making it that the cellName can't be edited.

    The fundamental problem is that there's no way in CDF to specify a callback on the cellName - because it's not a CDF parameter. Even if there was, it is more complicate than that - if you have CDF parameters with defaults which different between devices, and they have storeDefault=yes, then they'd need updating too.
