Micro-Cap SPICE Simulation is now Free

[@KissAnalog]

After 39 years in business - Micro-Chip closes their doors and gives away one of the best simulation tools that you could buy! Now - the best free software by a long shot! Very powerful - beautiful interface, lots of sample circuits, and library of parts is huge.

[@MrAj198]

Thank you for this video, I have never even heard of this software until a few months ago thanks to your video. After attempting to contact the website creator, I was only able to do a whois to discover that the website is set to expire on 2023-03-27. So unless a new website is put up, or that one is renewed (I tried e-mailing the support e-mail but it is no longer working) the software will be available on their website until March 2023.

[@BS-my2ky]

​ @Zakira Gur Their building is on the market for rent. If their website could go down at anytime, maybe it's good time if someone mirror their entire website. I'm so amazed at their program file's size. The manual is only 232pages and the program is under 20MB. Amazing!

Thank you! I appreciate you! I sure will - and let me know along the way if I’m covering what you want.

[@iwbnwif]

It’s all really great stuff so far. It’d be really nice to see some switch mode power supply designs in the simulator compared to the bench circuits you’ve already covered. Personally, I’m interested in ultra low noise switchers (both radiated and conducted noise). Also, the KISS U videos could be interesting to repeat with this sim and see the effects of value changes. Sorry for the long list 😬😇

[@KissAnalog]

Iwbnwif Yiw Thanks for the feedback - it’s awesome!!! I was already thinking I could make the Kiss U more fun and easy to learn so I’m happy to hear someone bring that up! Also, I’m chomping on the bit to get into more PS design!

[@pbaemedan]

Eddie, thank you for the information on micro-cap. 5 years ago, I was on an EMI tiger team and we were troubleshooting a RE 102 EMI outage. We found out that our company had dropped Pspice. When we looked into getting Pspice back the company refused any software that was not stand alone. We approached them and the 4,000 dollar price tag for micro-cap sent them over the edge. I need to verify my model library that I have with LTSPICE will work. This should not be a problem as long as micro-cap follows the Berkeley subcircuit definition.

[@KissAnalog]

Thanks for this feedback! Let me know if there are any problems. MicroCap does use Berkeley Spice as its backbone (unlike LTSpice which has its own math model that will import SPICE models). Microcap has several ways to bring in models - and I show some of that in other videos in my playlist:) Here's a link to one: kzbin.info/www/bejne/aWanp5l6Yrd0gJI Micro-Cap is very powerful and has a huge library already and a big library of circuits as well.

[@microknigh7]

Thanks for the heads up Ed. I currently use 5Spice coz it's so easy, but Richard (the developer) has retired it. Will defo have a play with MC12, so will be interested in any tutorials :-)

[@KissAnalog]

You bet! I’ve used 5spice too, and I think this is an easy transition. It’s basically retired too, but it is very mature and very powerful!

[@KissAnalog]

Let me know what you think. I’ll do some tutorials as well.

[@beamfinder8336]

I thank you for this info. I just took a quick look at it and the library of models is inpressive! Lots of transistor and tube models. You did a lot of product reviews lately and as you said you are looking for inspiration for further videos. I say make the name of your chanel come true and tell us something about analog circuite design. Like on the base of amplifier design, everything is some kind of an amplifier. How do different concepts of CCSs compare, simple JFET or the "ring of two" or cascoded BJT. Also current mirrors in a differential stage and their application could be very interesting. As I understood you are a pro at SMPS. You could make a video about designing them, especially the traps. Like the peak and mean switching current trought the choke or the switching transistor (buck or boost). A design "go trought" would be very interesting (choosing of the switching frequency, chosing of the appropriate choke and so on). Keep up the good work!

[@KissAnalog]

BeamFinder I really appreciate your feedback #BeamFinder and I am glad that you reminded me of my focus! One correction, I have tons of inspiration, but I have limited time... I hope someday I can do this full time - someday sooner than later so that I can post a vid everyday! But for now I want to know what my people want - from views it is reviews, but where I can share my most valuable experience has got to be in design and production of great circuit board designs;) if I got to toot my own horn;) I’m so happy that you found this - it is so powerful! It could kill LT if everyone actually gave it a chance - but there are fan boys that will stick to what they know - even if it is not even in the same category! This tool, we will have fun with. I think it is possible that our community could to nuts sharing cools stuff that we Learn and share - at least the at is may hopes. Glad to hear from you!!

[@KissAnalog]

Thanks Andrew! The Basso Books are awesome. I actually bought some SPICE models from him once, and I was planning on going over his newer ones in future tutorials;)

[@andyj2106]

Thanks for the heads up Eddie. For sure, do your circuits for your videos with Microcap, that would be fantastic as well as short and sweet tutorials. I've been using LTSpice - on the Mac because I'm a glutton for punishment!!! It's not bad in the sense it seems to work but the UI does my head in and there is nothing intuitive about it. I'll definitely give this a look and play.

[@KissAnalog]

😂 I know what you mean - best thing about LT is it’s free, but I found other packages that I used instead. I did purchase Microcap when I was consulting as I needed a real tool. I was the VP of Engineering at a small company and a really good young engineer was having all sorts of problems with LT that made it NOT free so we purchased him a copy of Beig Bag because of the low cost. It is astounding that we can get Microcap for FREE now!!

I am an LTspice and KiCad+ngspice guy, and they are ok, but sometimes drive me nuts in some areas. I will give a Micro-Cap 12 a try, it looks well designed, easy to use and it would be also nice to compare models and simulator quality itself. The huge parts library is definitively an enormous benefit, as many other programs lack so often. Downloaded, and archived, just in case.

[@KissAnalog]

That’s great feedback. Let me know what you think once you have a chance to compare.

[@bibo987945]

Interesting. I will give it a try. I have ever used several times of multisim to design a circuit for overload protection that really can save much time and the actual circuit does work well as the simulation result.

Boonedock Journeyman Great to hear from you - what spice tool do you feel is better? This is arguably one of the top 3 for a decade or so I am truly interested in what you think is a better tool. What I know is the owner of this tool retired and decided to give his work away free. I feel like we are so lucky that he decided to give it away.

I used this software at work when it was first released. It was really excellent to use, so friendly and accurate, but too expensive to use at home. It is nice to have access to it now. I wonder how long before some Microsoft update stops it working?

[@KissAnalog]

I agree with you on how nice the software is to use. I hope that it will last for awhile since it is a new windows 10 release. If it has problems with a future version of windows, it would be worth having a dedicated PC with windows 10;) That would be a lot less expensive than the software used to cost. It would be great if it became an open source product and just keeps alive with time;)

[@nigeljohnson9820]

@@KissAnalog I was using Micro Cap 3&4. A good test of a simulator is how well it handles a PLL with a digital phase detector. There are a number approaches that simulators take. Performing the circuit analysis in the time or frequency domain and then converting between the two. Some do a pure mathmatical analysis in the Laplace domain. Each have advantages and drawbacks, but I have found a good test is if they can they simulate a cd4046 pll type 2 phase/frequency detector. This is usually best handled by those that increment voltage and current in the time domain. When simulating such a detector implemented in a FPGA, I have used MathCad, but MatLab does it best. MicroCap was really good at analogue filter design. I spent some time using it to design flat group delay analogue filters for old analogue modem data transmission.

Here in January 2021. I discovered myself that Microcap became free only last summer in 2020. My history with Microcap goes back to the early 1990's using Version 3 when I was studying EET, then about a decade later I dinked around with Version 6. Anyway, it's the end of an era. I hope to try Version 12. I still have Version 3 as well as the book/manual.

[@KissAnalog]

Thank you for sharing this! I hope this new version makes you as happy as it did me. I think the last copy I purchased was version 6 maybe;)

By the way, also back in the early 90's, I was also concurrently using a program (also in DOS) called Micro-Logic, aka μLogic, for doing digital logic schematics for my college engineering courses. Later versions I never could find online so at least I still also have that old version. (Lot's of "also's" in that paragraph)

​@@KissAnalog ... It's been awhile since I've used Cap but I hope to get back into it. It brings me back to the 1990's. This situation of Cap becoming free at the end of its life reminds me of another favorite software of mine that had the same thing happen to it. It was a 3D CAD modeling & animation software called TrueSpace 3D, that would sell for hundred$ each version & then finally the company got bought out by Microsoft & so the last version became free, which this happened over 10 years ago. Must've been frustrating to those who paid for the latest software version for $600 & finding they could have just waited. Bittersweet story as well.

That's great that you got this. Did you get the CD version which has the manual and whole package? It sounds like all the files did not unzip in the mc12 folder. Try downloading the CD version then run the setup.exe. You may need to unzip the file into the mc12 folder. After installing, go to the help menu and get the latest updates. Let us know if that works.

Hi, would it be possible to get the microcap source code? Maybe this is a possibility to start an open source project

[@KissAnalog]

That's a great idea. I have tried to reach out, and maybe I'll try again. The thing is, Microcap is so mature and so far ahead of most other programs - there's not much more to do with it. Also, you can build parts and import so there is lots of room to grow.

Just SUBSCRIBED! Been looking for an RF circuit simulator and many look like toys or are really limited. I am now retired and want to "close-out" by getting back into discrete RF circuit design (my life and work took me other places!) so this looks the most promising for "my-budget!" Just seeing this, I was wondering if it has dual-gate MOSFETs and RF toroidal inductors? Or, if you can edit or download a new component for the future to keep this software viable? Also, hats-off to Spectrum-Soft for doing what they did--as you said they could have capitalized much more than they did! Anyway, great video and I DO look forward to going through your tutorials.

[@movax20h]

@@KissAnalog After playing a bit there are some minor issues when using it on Wine. The file save/open dialog is broken. You can't save any circuits. It says it is saved, but it isn't. Similarly, open dialog shows previous and can be used to open demo circuits, but you can't close the window and continue. Switching in winecfg to Windows XP compatibility, instead of default Windows 10, change the way file dialog works, and fixes it. This way you can save circuits and make it work. I did seen some report of crashes during use of Text mode, to add/ edit models by hand in SPICE language, but I can't reproduce it yet. Overall, the library of components and ability to add new models, with a lot of parameters easily, is very impressive. But other than that the UI and user experience is quite a bit of mess. I will continue using it, but I don't like how it is designed overall.

I'm running Manjaro at the moment, but when I gather the time and patience to install everything I will be going back to arch. Linux itself is a steep learning curve, but very satisfying when you get it right. I did do a bit of homework, on the back of others who went before me, and all though I haven't proved it myself yet, Micro-cap, can allegedly be run, and run well on linux. I found the instructions with a google search. There are many free spice type programs free and available for linux. I think it's a kind of sickness on my part though, I tend to (when patience on the day allows) try to find workarounds for things that shouldn't work lol. I have had mixed success, but seeing others do it is somewhat of a motivator I think. I will get back to this, just life is slightly hectic at the moment, but I like learning (things I'm interested in), and eager to relearn what I have forgotten over time, strange as that sounds. Best wishes. Dan.
