How to use .ALTER statement for models

hspice .alter

Hi

In Hspice how to use .ALTER and .INCLUDE statements to change the model files of slow, fast and normal corners


i know that if i use .LIB statement to include the model file
it can be changed by first using .DEL like below and .DEL with proper one

.LIB "file1" TT
.....
...

.ALTER
.DEL LIB "file1" TT
.LIB "file1" SS
....
...
.END

so similarly how to deal if i am using .INCLUDE statement for Models

Thanks
Kiran

hspice alter

As far as I know, you don't need using the " .dle lib....", if you want to change the model file, you can using the ".alter" and ".include ...." directly.
You can also refer the manual of Hspice for more information.

but it could not print the .ALTER results where as it printed results related to "model_fast" file
and gave few warnings and stoped

.include ".../model_fast"

.PRINT DC V(DATA)


.ALTER
.include ".../model_slow"

.END

.alter in hspice

Don't put .alter statement for first model.

From second corner onwards, put .alter and .include statements
