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

Description of MOS tran with nmos param

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.

  • Not really sure why you had to change the syntax of the model files.

    BTW, I think you edited your last posting in this thread, rather than adding a new one. If you edit a post, there's no email notifier sent to people subscribing. So if you post something which doesn't require an answer, and then edit it to include a new question, it's quite possible nobody will even notice that you've asked a new question.

    If you need diode models, either get them from the foundry you're using (best solution), or if you want something representative, then there are design kits such as the Cadence GPDK (Generic Process Design Kit) for various nodes, as well as some similar university PDKs - e.g. from NCSU.
