LTspice Tips Encrypted Simulation Library [Copy link]

When I used TI's simulation Spice model, I opened it and saw garbled code. I thought I had loaded it wrong, but later I found out that the code was encrypted. So is it to prevent me from taking advantage of it? Is it a magic modification?

Encrypt it up guys!!!

To use Ltspice for encryption, you need to use the command line that comes with Windows. It is still a bit difficult for those born after 1995 to use it, but this can't stop us from trying it out!

Be sure to copy the original when encrypting! ! ! ! ! !

WIN+R CMD to enter the console. The console operations are as follows

First, let's take a look at what it looks like before encryption, as follows

* define a PWM Generate * Name is PWM_G means PWM Generate * PWM output D1 * | PWM output D2 * | | Ground .subckt IS801 D1 D2 GND *in this here V1 is Vinitial V2 is Von *Ncycles remove always have *Vxxx n+ n- PULSE(V1 V2 Tdelay Trise Tfall Ton Tperiod Ncycles) *setting dead time and frequency,Duty .text DT="0.05u"

The encryption looks like this:

The encrypted image looks like this:

Then, the simulation results are the same.

However, after encryption, the LTspice model symbols cannot be retained, so you need to prepare the model symbols for transmission. Otherwise, others will not be able to simulate even if they get the simulation library code.

That’s all for today. Bye~

I found that there is spice code in the avago manual, HCNR200.

How can I quickly find out that these code manuals contain spice codes?

I couldn't find it quickly, I just found it by accident when reading the manual
