HPEESOF_DIR is set to an invalid directory about ads-matlab-interface HOT 7 OPEN

Hi,

Indeed, this is because of wrongly set PATH. By default, the interface does not modify the system PATH, but only locally for the MATLAB session.

There is a known issue when you try to set a path like ADSInstallationDir = 'C:\Program Files\Keysight\ADS2017\' (with the backslash at the end). Did you do that in the first place?
Please check that you don't have the backslash at the end of the path and restart MATLAB, so it clears previously-stored environmental variables.

As another, permanent solution, you can set the required environmental variables manually in Windows. List of them you can find in ADS documentation, or inside the source code of the interface.

Hi Oleg,

Thanks for your reply. I do not have a backslash at the end.

I set the environmental variables manually as you suggested.
%HPEESOF_DIR%\bin%SIMARCH%;%HPEESOF_DIR%\bin;%HPEESOF_DIR%\lib%SIMARCH%;%HPEESOF_DIR%\circuit\lib.%SIMARCH%;%HPEESOF_DIR%\adsptolemy\lib.%SIMARCH%;%PATH%;

Now the command

system('hpeesofsim.exe')

gives -1.0737e+09.

However, I still have an error in ADS.RunSimulation(). The message is

Error using TADSInterface/RunSimulation (line 2072)
Cannot run simulation. The exit code is 1

Please advice. Thank you so much!

Hi again,

I was able to run hpeesofsim in cmd using instruction in https://edadocs.software.keysight.com/eesofkcads/ads-command-line-simulation-on-64-bit-windows-654133585.html

but when I went back to run hpeesofsim in Matlab I had the following error.

system('hpeesofsim.exe')

And I still cannot run ADS.RunSimulation();

My workaround is to use a batch file to replace ADS.RunSimulation(). It would be useful if this issue can be resolved. Thanks!

Hello yu586sjc
Looks like you are trying to use this interface in ADS2021. I also meet the same issue. My solution is setting the Win10 env according to https://edadocs.software.keysight.com/eesofkcads/ads-command-line-simulation-on-64-bit-windows-654133585.html.

Hi yorkliu228,
Thank you for sharing!

Hello,

I am able to run the demo for reading data, but I have trouble running the second demo. I run system('hpeesofsim.exe') as suggested by Oleg. Below is my error message:

============================================

system('hpeesofsim.exe')

HPEESOF_DIR is set to an invalid directory. ""C:\Program Files\Keysight\ADS2017"\bin" does not exist. Error setting up command line: HPEESOF_DIR is set to an invalid directory. ""C:\Program Files\Keysight\ADS2017"\bin" does not exist. hpeesofsim (*) 531.update1.1 Dec 12 2020, MINT version 5 (64-bit windows built: Sat Dec 12, 2020 05:23:54 +0000)

ans = 1

===========================================================

It looks like the path string did not append properly, as evident by ""C:\Program Files\Keysight\ADS2017"\bin" I set the path as below

ADSInstallationDir = 'C:\Program Files\Keysight\ADS2017'; ADS.SetADSPaths(ADSInstallationDir);

It works fine for the read demo, but not for the simulation demo. I am using Matlab 2020b.

Ok, I have the same problem and solved it. Change the line 1485: EnvVarValue = ['"' EnvVarValue '"'] to EnvVarValue = string(EnvVarValue).
Hope work.
