Greetings,
I created a circuit with Eagle 8.0.2 to simulate using LTspice. When I hit the LT Spice button, I get the error LTspcieIV (scad3.exe) not found from Eagle: ltspcie.ulp. I've installed the latest version of LTspice XVII which is designed for use on Windows 7, 8, and 10. LTspiceIV is for windows XP which will not be supported much longer. Is there an update or a ulp that will use the newest version of LTspice XVII? If not, are there any instruction on modifying the ulp to use LTspcieXVII?
Hello P-brane,
I hope you're doing well. The LTspice ulp that ships with EAGLE isn't compatible with LTspiceXVII. With that said prior to the acquisition I had been working on porting it over to work with LTspiceXVII and across all three operating systems however it's not 100% complete, I still haven't finished the Mac port. Since you are one Windows it will work for you.
You can download the updated ULP in its current state from here:
https://github.com/cadsoftcomputer/EAGLE-LTSpice-port-to-Linux-and-Mac
It's not an official release but if you need any help please let me know and I'll help you out.
Please accept as solution if my post fully resolves or you issue, or reply with additional details if the problem persists.
Let me know if there's anything else I can do for you.
Best Regards,
Hi Jorge,
I follow the instruction, but get the following error:
../ltspice.ulp(3971): Number of arguments for function 'assign_rootpath() is incorrect
Export and export setup produces the error. The icons for dignlink.png and LTspice.png are missing too. It seem like Eagle does not know about the location or path of LTspiceXVII. Is there an environment variable that needs to be defined?
I tried the suggested download and got the error message:
C:/EAGLE 8.1.0/ulp/ltspice.ulp(697): Unable to open the include file 'debug.ulp'
Thanks for the help!
Hi,
We are also having a similar issue with spice.
I also replaced the .ulp with the ltspice.ulp from GitHub but getting a similar message c/eagle 8.2.0/ulp/ltspice.ulp(1): Unknown identifier 'Skip'
Did i miss anything?
Kind Regards, Craig
I have installed updates from github with some success.
I deleted all prior versions of the files related to LTspice interface and installed per git hub instructions
One instruction error is lib folder vs lbr folder ?
I was able to import a simple schematic from latest LTspice version i
I have two problems
1)Icons for the ULP's on the toolbar are not loading
2)I am stuck in debug mode , having to step through the debug screens to use the import function
Have not tried export , only planning to use import at this time .
Thanks
Hi there Jorge
Trying to get your LTSPICE XVII ULP to work on Windows 7 x 64, thanks for writing this code.
Tried to install all the new files, I think I got it right?
But when I go through LTSPICE setup in Eagle, using new ULP I get this error:
Can't open C:/Eagle/8.2.2/eagle-ltspice
I can say Cancel, but i think export setup didn't work...when trying to export a schematic after saying cancel I get the whole "Spiceorder not found" errors I got before I tried to new ULP's at all, for every part in my schematic
Did I do something wrong?
Thanks in advance for your help!

Hi again
I also have an ubuntu 14 machine. I could install Eagle on that along with wine-ltspice but does your ULP work on linux?
Can the Linux Eagle ULP "jump to wine" to run LTspice? If so I can give that a try, but I am not sure if the ULP can cross operating systems. If it won't I probably will focus on fixing the Windows ULP issue I wrote about earlier today.
Thanks again Jorge

Hi there!
Thanks again for the reply. I still get the error message while doing the setup export (see attached screenshot), but the 3518 simulation does open correctly.
So I will ignore the message in the screenshot going forward and work on the library correspondence.
I greatly appreciate your quick responses and your help w/ this.

Hello Jorge,
I hope you're having a a great time.
I'm using LTSpice XVII and Eagle 8.5.0. As you mentioned I downloaded the files from github. I copied the folders as suggested. I opened eagle and clicked LTC SPICE and same error continues (LTspiceIV scad3.exe not found). I'm suspecting that there should be something done after copying the files which I'm missing. Could you please help me with the next step?
Thank you.
Best regards,
Lomesh

Is there a particular reason you are doing this? As of v8.4.0 there is a SPICE engine built directly into EAGLE. I'm not sure it's covering 100% of the features of SPICE available in the ngspice engine yet but it seems to work well. Maybe this would be a better option?
Best Regards,

Thanks for the response Rachael,
There is no particular reason in using Eagle 8.5.0. I was not aware of this situation that I have to do some additional setup.
Do I still need to do any additional setup to link use LTspice with eagle 8.4.0?

Hello,
I didn't mean why are you using EAGLE 8.5.0, I meant why are you using LTSpice? Since EAGLE 8.4.0, there has been a native SPICE simulation engine built directly into EAGLE so there is no need to use LTSpice now. Just draw your schematics in EAGLE, assign models to the parts and run the SPICE simulation engine directly in EAGLE.
See the following videos on the Autodesk YouTube channel for more details of how to use this capability:
https://www.youtube.com/watch?v=JtytRPefUxk&list=PL1rOC5j_Fyi46HXbWw8QFAtEWRJ-hfpBa
The whole LTSpice with EAGLE thing was always an awful kludge to try and shoehorn simulation capability into the EAGLE workflow. Since Autodesk have been investing so heavily in EAGLE, one of the huge new features was this SPICE integration directly within EAGLE.
