There are Device Modeling Reports for LTspice in this page. LTspice models which I made are sold at Gumroad.
Please try free sample of a spice model of KYOCERA.
I uploaded Device Modeling Reports at Gumroad, but you need your E-mail address for downloading reports. I think I will not get list of customers and it is make you troublesome. So I moved the reports to my blog.
Commercially available spice models are expensive At a famous EC site, one model of solar panel costs more than 10,000 yen(over 100 dollar). I think it's very expensive.
I hope that more engineers can simlate electronic circuit more correctly, and they can get the spice models at a lower cost.
Low social status of electronic circuit simulation In my previous job, I was involved in electronic circuit hardware design (around a microcomputer) at an electrical equipment manufacturer.
I strongly felt that electronic circuit simulation was not trusted. The reason is that there is no spice models used in the product, and the accuracy of the electronic circuit simulation is low.
In most projects, electronic circuit simulation is used for the purpose of confirming the rough behavior of the output waveform of the circuit. But if the result does not match between the prototype board and simulation result in the review, "This simulation cannot be used".
For raising rate of your simulation, Correct spice models is needed essentially.
