when trying to use mostt_stat in Xyce i get an error:

...
Parameter VFBO for model X1:XM3:SG13G2_HV_NMOS_PSP contains unrecognized symbols:
 {-0.89839*(1+(sg13g2_hv_nmos_vfbo_mm-1)/sqrt(m*l*w*1e12))}
*** Xyce Abort ***

if i change ihp-sg13g2/libs.tech/xyce/models/sg13g2_moshv_stat.lib to

...       
* ngspice statistical parameters
.param sg13g2_hv_nmos_vfbo_mm        ='gauss(sg13g2_hv_nmos_vfbo_mm_norm,   0.004,  mc_ok)'
.param sg13g2_hv_nmos_rsgo        ='gauss(sg13g2_hv_nmos_rsgo_norm,      1e-9,   mc_ok)'
...

it simulates.

the ihp-sg13g2/libs.tech/xyce/models/sg13g2_moslv_stat.lib has no *vfbo_mm. may be there is something wrong.

@olisnr we are aware of that. Xyce monte carlo simulations are still not fully supported. It is on our list.
