EM is a BSIM3/BSIM4 parameter, and its default is 4.1e7, but the Berkeley code doesn't have any restrictions on its value -- if it's negative, the code skips a block in the 1/f noise evaluation.

If you're not doing noise analysis, I'd ignore it. If you are, I'd contact the vendor and ask why you're getting that message.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
