[SOLVED] The problem of not being able to compare calibre LVS mosfet

[zzangkwang]

Hello
We found something strange during layout design. Even if the chemical mosfet size and the layout mosfet size are different, they pass through the LVS.
Even if I design an inverter, which is a simple circuit, LVS can't compare.
But resistance size is compared by LVS..
What kind of problem?

I am having trouble understanding the problem (or
perhaps the problem is that there isn't just one).

You can pass connectivity and fail parameter compare,
or vice versa (so long as the device is identified).

Circuit-level connectivity may fail for real or bogus
reasons. Not putting proper pins on proper layers
in proper places is one. Hand-building devices but
omitting "recognition features" is another. With not
one bit of factual input (let alone inputs and logs)
wild guesses are all you can expect.
