'Internal error found in spectre at time' during transient analysis

syafiq

Hello,

I experienced below error while running my transient simulation. Everything looks fine when I set t=1s. But when I change to more than 1s, I got below error. I have no idea what does it mean. But the error got stated to contact Cadence. I hope people in this community can give some advice.

I am using BSIM4 mosfet parameter file and Cadence IC6.1.4.500.6.

Transient Analysis `tran': time = (0 s -> 1.6 s)
************************************************
Important parameter values:
start = 0 s
outputstart = 0 s
stop = 1.6 s
step = 1.6 ms
maxstep = 32 ms
ic = all
useprevic = no
skipdc = no
reltol = 1e-03
abstol(V) = 1 uV
abstol(I) = 1 pA
temp = 25 C
tnom = 27 C
tempeffects = all
errpreset = moderate
method = traponly
lteratio = 3.5
relref = sigglobal
cmin = 0 F
gmin = 1 pS

tran: time = 50 ms (3.12 %), step = 18.88 ms (1.18 %)
tran: time = 132.3 ms (8.27 %), step = 15.65 ms (978 m%)
tran: time = 200 ms (12.5 %), step = 2.835 us (177 u%)
tran: time = 281.5 ms (17.6 %), step = 15.23 ms (952 m%)
tran: time = 366 ms (22.9 %), step = 7.47 ms (467 m%)
tran: time = 450 ms (28.1 %), step = 17.31 ms (1.08 %)
tran: time = 523.8 ms (32.7 %), step = 10.59 ms (662 m%)
tran: time = 600 ms (37.5 %), step = 6.607 us (413 u%)
tran: time = 681.3 ms (42.6 %), step = 15.16 ms (947 m%)
tran: time = 761 ms (47.6 %), step = 4.965 ms (310 m%)
tran: time = 850 ms (53.1 %), step = 11.42 ms (714 m%)
tran: time = 920 ms (57.5 %), step = 6.82 ms (426 m%)
tran: time = 1 s (62.5 %), step = 2.882 us (180 u%)
tran: time = 1.081 s (67.5 %), step = 14.75 ms (922 m%)

Internal error found in spectre at time = 1.0995 s during transient analysis `tran'.
Encountered a critical error during simulation. Submit a Service Request via Cadence Online Support, including the netlist, the
Spectre log file, the behavioral model files, and any other information that can help identify the problem.
FATAL (CMI-2010): Assertion failed in file `devices.cc' at line 6545.

    Hello Andrew,

    Thanks for your feedback. May I know where to download the hotfix or MMSIM13.1/MMSIM14.1?

    Cadence license will also work if using other than MMISM12.1 which I have right now?

    Thanks
