Re: 20nm PTM file not working in LTspice
Say Die, Your 180 nm model file, "180nm_whole.model", can be used in LTspice, because it uses LEVEL=49 models.? The names of the MOSFETs on your schematic must be "CMOSN" and "CMOSP". However, the 20

I understand, but LTspice Help doesn't even mention the possibility of a print step parameter. No matter, there are much bigger issues to settle. -- OOO - Own Opinions only If something is true: * as

Actually, no, that is not their filenames. The actual filenames are "20nmFinFET.model" and "180nm_whole.model". Andy

Re: 20nm PTM file not working in LTspice
No, ".TRAN 1ns 120ns" is correct too. When there is more than one parameter, the first parameter is the print step size.? LTspice ignores it when it is there, because LTspice never prints

Re: 20nm PTM file not working in LTspice
Make sure to let us know when you have done that, and tell us the name of the file. Here is more advice about your schematics: (1)? Nodes (nets) can have only one nodename.? In LTspice, a "Label" is

Re: 20nm PTM file not working in LTspice
Andy, the .TRAN statement is .TRAN 1ns 120ns. Probably meant to be .TRAN 120ns 1ns, where the 'superfluous 's'? is indeed accepted. -- OOO - Own Opinions only If something is true: * as far as

Open the HSPICE manuals and read.? It's several hundred pages. You can't.? You should not try.? There is no established way to get from one level to another level. You need to start with the

Re: 20nm PTM file not working in LTspice
Not now, since Andy has said that they won't work in LTspice. Instead, first try to find 120nm models that will work in LTspice. Then, if your 120nm circuit works, try to find 20nm models that work in

Re: 20nm PTM file not working in LTspice
It is actually OK.? Nothing wrong with writing "120ns". Some would prefer to omit any letter after the first one.? But SPICE was created in such a way that you can write "nV" or "nanovolts" or

Re: 20nm PTM file not working in LTspice
Yes, but you uploaded two files instead of a .ZIP, and didn't upload the model files in it. I looked at your 120nm .ASC. I'm not an expert in IC design, but it looks as though it might work. But
