Need an industrial strength circuit simulator?

It's now Free!

If you have been looking for an industrial strength circuit simulator and analyzer, look no more because Micro-Cap 12 is now FREE as! of July 4, 2019. The company is closing its doors and has offered their state of the art simulator free with no license key needed. The program is fast and easy to use, not a lot of bloat and no need to procure a monthly use fee. Look at some of the features packed into this 12th generation software introduced back in 1982!
