You have helped me . I have done it accorrding to your direction. And I delete "level=49" in the spectre model file that produed, because when I simulate netlist by spectre, there are some error .I want to know whether this will impact simulation percision.
Can you firstly tell me what error you are getting? I mean, it is better not to delete the level. It is always a risk, in the sense that there could be some other level models which might not model some second order effects as model 49.
"Spectre provides the SPICE Reader to let you simulate existing SPICE netlists with Spectre"
I think that this feature exists only in version 5.0 and above
Read the documentation
The problem is as simple as this. Spectre defines level 49 model as 'bism3v3'. You follow the following procedure.
1.First spice file contains all the letters in uppercase letters. Write a simple C program to convert all the upper case letters into lower case letters.
2.Delete the '.' before the model
3.Add the statement in the beginning of the file as
simulator lang= spectre
4. Remove any brackets in the model file.
4. After model include your given transistor name in lower case letters for example 'pfet', 'nfet' or what ever the name you gave for the transistor.
6. After that you include bsim3v3 in lower case letters
7. After that you specify its type
type=p for PMOS
type=n for nmos
7.If your version of specre supports recent version in bsim3v3 you can include now
version=3.24.
version numbers 3.21,3.22,3.23,3.24 are all supported on ic5.0. All are same with improved curve fitting for capacitance models for recent versions like 3.24.
8. Remove '.m' extension to the model file and give '.scs' extension
leave the rest of the things as it is. It should work now. Other wise write to me with your problem. You can completely remove the level=49 if you specify version. No harm. Remeber that spectre is case sensitive where as SPICE is case insensitive.
