Hi, friends!
For  spectremdl simulation I prepare three type of input files (simulation from terminal window)
1)      netlist.scs – circuitry and simulator options
2)      corners.scs – altergroups
3)      netlist.mdl – measurement procedures and altergroups, which will be run
Examples:
1)
simulator lang=spectre
global 0 vcc! vdd!
include "/space/home/eboyarinov/TSL018_IO/Models/models.scs"  section=tt_18
include "/space/home/eboyarinov/TSL018_IO/Corners/corners.scs"

parameters C_load=32p vcca=2.3 vccb=2.3 PERIOD=100n TFRONT=1n DELAY=20n  
    ……………………………
M2 (D G S B) nhv w=1.6 l=0.35 as=0.768 ad=0.768 ps=4.16 pd=4.16 m=32
……………………………
V0 (G 0) vsource type=pulse val0=0 val1=vcca period=PERIOD \
delay=DELAY rise=TFRONT fall=TFRONT width=PERIOD/2-TFRONT
………………………………….
tran tran stop=3*PERIOD errpreset=moderate write="spectre.ic"

simulatorOptions options reltol=1e-3 vabstol=1e-6 iabstol=1e-12 temp=125.0 \
tnom=27 scalem=1.0  scale=1e-06 gmin=1e-12 rforce=1 maxnotes=5 maxwarns=5 \
digits=5 cols=80 pivrel=1e-3
2)
slow_1 altergroup {
include "/space/home/eboyarinov/TSL018_IO/Models/models.scs" section=ss_hv
include "/space/home/eboyarinov/TSL018_IO/Models/models.scs" section=res3t_high
include "/space/home/eboyarinov/TSL018_IO/Models/models.scs" section=diodes
include "/space/home/eboyarinov/TSL018_IO/Models/models.scs" section=res2t_high

parameters vcca=1.4 vccb=1.4 C_load=17p R_load=2k
}

In this netlist I have absolute value of width and length! And scale=1e-06!
Simulation command $spectre netlist.scs passing w/o error.
But when I run $spectremdl netlist.mdl i see error:

Instance length or width does not fit the given lmax-lmin or
       wmax-wmin range for any model in the `I43.I35.M0.nhvstat'

why for spectremdl scale=1e-06 doesn’t work?
why simOpt "scale" don't work for altergroup when models was changed  >:(
Thanks!

Hey Andrew,

Could this be due to wrong or no value assigned to CDS_Netlisting_Mode variable?

-CA

Thanks guys, thanks Andrew!
Andrew, sometime I read your posts on  http://www.cadence.com/Community/forums/
with tags “ocean”  ;)
I run test which you prepare, simulation  finished successfully
I think spectremdl goes crazy when alter or use file “montetest.scs” (Probably I am not right, before I spoke about the sizes
of transistors, but manipulation with models may give and others errs ).
Earlier i tried to write corner analyses for ADE and has problem with syntax:
corAddModelFileAndSectionChoices( "018um" "TSL018_IO/Models/montetest.scs" '( "mont" )
)  
;i change file “montetest.scs”  to concluded all content in one section "mont",  but this don’t help me


montetest.scs contains:
-----------------------------------------------------------------
simulator lang=spectre insensitive=yes
parameters rmatch=0  cmimmatch=0 vtnlvmatch=0 vtplvmatch=0 vtnhvmatch=0 vtphvmatch=0 vtnhvmatch5v=0 vtphvmatch5v=0  accapmatch=0 mfcmatch=0

statistics {
     mismatch {
           vary rmatch dist=gauss std=1
           vary accapmatch dist=gauss std=1
           vary mfcmatch dist=gauss std=1
           vary vtnlvmatch dist=gauss std=1
           vary vtplvmatch dist=gauss std=1
           vary vtnhvmatch dist=gauss std=1
           vary vtphvmatch dist=gauss std=1
           vary vtnhvmatch5v dist=gauss std=1
           vary vtphvmatch5v dist=gauss std=1
           vary cmimmatch dist=gauss std=1
           }
     }  

----------------------------------------------------------------------
For decision this problem I change models only in *.scs file and change parameters in *corners.scs file.
anyway Thanks!
