Hello
I build circuit in Ltspice but need to put special type of transistor instead of existing , so is there a fast way to change all transistor ? or I must change each of them separately ?
thanks

 

I know two ways.
The First: Open the file with extension "asc" text editor (for instance Note pad). Change all old name on new name (in editor there is group (wholesale) change).
The Second: use the command AKO. For instance .model oldname ako: newname.

 

I have .lib file... external library
now how to change .lib file with another ??
thanks

 

Can in detail tell what files you have.
Better if you load their own files and in more detail tell that you necessary.

 

I find a simple osc circuit that use IBM 65 nm .lib file, and I want to use 90 nm transistor from another library, so can I change in one place to change all the circuit transistors or I must change all of them manually?
Thanks
