Encrypted Spice model for altair04-900

[Felix_Mari]

Hello!
I am currently designing a flyback converter with the altair04-900.
The .lib file in the spice model folder is encrypted. I cannot open it neither with Altium nor with ltSpice.

I would like to know, which simulation software can decrypt it? And, more specifically, if there is any free simulation software?

Hi,

you cannot "open" an encrypted model, just use it.

Is it working in LtSpice ?

Hi. Maybe I did not explain myself well: I cannot use/simulate it.
ltSpice builds a valid symbol and reads the non encrypted .SUBCKT lines
but cant read the rest. From what I've read, ltSpice cannot read
encrypted .lib files unless specifically encrypted for ltSpice.

Aha...ok, so you could ask STM to add a encrypted model for LTspice .

Already done. I just wanted to know what software to use for the already
existing file as I am sure I'm not the one trying to use it

>I just wanted to know what software to use for the already

seems its: Cadence OrCAD

PSpice might be yes. Maybe someone knows about a free alternative
