Spectre simulation can not run when use Liberate to characterize the T22nm IO cells

liberate version:LIBERATE 17.13.076

spectre tool:IC61/616ISR6: mmsim15.10.627-ISR12

when use liberate to rek T22nm IO cells, spectre simulation will report error likes  blews:

* Spectre exit code : 134(user/syetem interruption)

Then, I use the cormmand : spectre +aps +spice sim.sp, to run simulation with the  generated  sim.sp file . It would generated a internal error like below. I want to konw  what  should I do to solve the  problem about the REK simulation can not run.  Look  forward to your reply. THANKS.

    Most likely you're just using too old versions of the software. The bsim6 is a relatively recent model, and you're using a simulator from 2015, and an old version of Liberate. You should use IC6.1.8/SPECTRE21.1/LIBERATE217 (I think - certainly a Liberate version from this year would make sense rather than one from 5 years ago).
