About LTspice RAW file format

Question asked by Dera on May 31, 2018

This question has been solved.

It was a really simple structure.(Swap X and Y)

I am ashamed of having suffered without noticing it.


I want to automatically retrieve LTspice data(Raw file) at Excel VBA.

Please tell me the structure of the raw file.


>Situation(Command Line Simlation)

1. C:\"Program Files"\LTC\LTspiceXVII\XVIIx64.exe -Run -b -netlist xxxxxx.asc(Excel VBA access)

2. C:\"Program Files"\LTC\LTspiceXVII\XVIIx64.exe -Run -b -ascii VBA access)

3. Excel VBA read xxxxxx.raw

4. Simlation OK>END NG>automatically change and go 2.(Excel VBA)
