LTspiceIV (scad3.exe) not found, How do I use LTspiceXVII?

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?

Hi p-brane,

I hope you're doing well. I've recently updated the github, because I ran into that same error. I fixed it already, but I still have one more to resolve. I will let you know once I have the other issue resolved. I hope to have it fixed before the end of the week.

Sorry for the inconvenience.

Best Regards,

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 minusculelighting,

I hope you're having a good day. The github link includes the debug.ulp, you have to copy it to your ulp directory so that the ULPs will recognize it there.

The port isn't done yet which is why I have the instrumentation still in the ULP. I still have some work to do on it.

Let me know if there's anything else I can do for you.
