problem in include file in Hspice

[rajamrish]

hi everyone,

Can any of u help me with this.
i have downloaded the PTM file for 32nm FINFET.

the file has inculed statement as below,

* This is sub 32nm FinFET prdictive model

the folder also has the soinmos1,soinmos2,soipmos1,soipmos2 PM file.

but when i am running this code it is should error in included statement.

can any1 of u help me with syntax.

please i help ur help urgently.
thanks

You are probably not starting your simulation from the directory where these files reside. Put this latter directory in your library path!

Another possibility would be to replace the "./" notation - which means: "from this directory" - by its absolute path.

 

[rajamrish]

i tried both your solution but still not working.
can u help me with some more option.

 

[erikl]

Show your Hspice control file (by which you start your simulation), and the full error message.

Hi rajamrish

Try to copy your model file to directory you run hspice and do like this

.lib 'new_mm018.l' TT


I think it should work. Use dot lib not dot include

 

[rajamrish]

Thanks erikl,
I am herwith attaching the file i am using and the error are,
**error** (e:\sram\lib\32nm_finfet.sp:74) duplicate parameter being set or the number of element nodes is not within the range of 3-7.
**error** (e:\sram\lib\32nm_finfet.sp:74) difficulty in reading input
looking forward for ur help,
please help me with this

Hi rajamrish

1/Change your spice desk :

.include 'soinmos1.pm' * front soi model card <------ old one is .lib
.include 'soinmos2.pm' * back soi model card

2/Change your ptm (i pick soinmos1.pm as example)

.model nmos1 nmos level = 57 (new one)

.model nmos1 nmos1 level = 57 (old one)

3/ Do same thing with others (pmos)

**error** (e:\sram\lib\32nm_finfet.sp:74) duplicate parameter being set or the number of element nodes is not within the range of 3-7.

Could be possible that Hspice doesn't like the redefinition of the parameter wdg on line# 50 of the file 32nm_finfet.pm (earlier definition on line# 9), even if these definitions occur in two different subckts. Try and change the parameter wdg to a different name on line#s 50 and 74..79 .

BTW: Your FINFET32.zip file contains the file 32nm_finfet.pm, whereas the error message names the file 32nm_finfet.sp ???

Thanks erikl,
To run the file in spice i an change it to .sp
The file is same only the extinction of file is change.
i hope this works.
