Spice lib

StreamCX

 I convert my project from 5 to 6 version.

When I try to simulate with old library this message appears.

When I write "simulate lang = spice" in My *.scs lib file this appears

How can I use this model to simulate project? That lib works in Cadence 5.

 //There is no name like nmos4, pmos4

* Nterest

.model  kn nmos level=2 phi=.65 tox=55n xj=.34u tpg=0
+ VTO=0.5 LD=0.15u  WD=.04u  UO=460
+ NSUB=25E+15
+ CJ=0.0004 
+ GAMMA=1.1

.model  kn_nat nmos level=2 phi=.65 tox=55n xj=.34u tpg=0
+ VTO=0.5 LD=0.15u  WD=.04u  UO=460
+ NSUB=25E+15
+ CJ=0.0004
+ GAMMA=1.1

.MODEL  Kp PMOS LEVEL=2 PHI=0.65 TOX=55n XJ=0.4U TPG=0
+ VTO=-1.1   LD=.25u WD=.04u  UO=160
+ NSUB=1.1E+15 
+ CJ=3.1E-04
+ GAMMA=0.27
.MODEL  kp_lVt PMOS LEVEL=2 PHI=0.65 TOX=55n XJ=0.4U TPG=0
+ VTO=-1.1   LD=.25u WD=.04u  UO=160
+ NSUB=1.1E+15 
+ CJ=3.1E-04
+ GAMMA=0.27
.model diod d(is=1.0e-12 rs=2 cjo=1p bv=50 vj=.6)
.model diode d(is=1.0e-12 rs=2 cjo=1p bv=50 vj=.6)
*.subckt mkn d g s b
*mkn d g s b kn w=w l=l
*.ends mkn

I try add  .model  kn [b]nmos4[/b] level=2 phi=.65 tox=55n xj=.34u tpg=0
+ VTO=0.5 LD=0.15u  WD=.04u  UO=460
+ NSUB=25E+15
+ CJ=0.0004 
+ GAMMA=1.1

That does not solve the problem.

  • My guess is that  you have not set:

    setenv CDS_Netlisting_Mode Analog   

    (for csh) or:

    export CDS_Netlisting_Mode=Analog

    for bash/ksh.

    Because of that, the instance lines in the spectre netlist are showing the component name rather than the model name. Rather hard to be sure, because you didn't show the netlist.

    Note also that it's better to show the actual text, rather than a picture - as these are easier to look at and search in future.

    Regards,

    Andrew.
