does not fit the given lmax-lmin
Hi all,
I need to use some PMOSFETs which have a length of 40u, but in the .scs file provided by TSMC, the length can not be larger than 20u, so I modify the lmax=20u to 50u in the file. But, when I simulate the circuit in Spectre it still says: “IXX.MXXX: Instance length or width does not fit the given lmax-lmin or wmax-wmin range for any model in the ‘pch’ group”, what should I do to solve this problem? Thank you in advance.
Best regards,
Terry
