Set SEED in JoSim

[LuigiDIP]

Hello Johannes,

First of all, thank you for your work on the JoSim simulator—it is extremely valuable to the superconducting circuits community.

I would like to report a potential issue related to random number generation. I am trying to change the seed used for randomness. According to the documentation, this should be possible using the command
.option seed=4190754512324517577.

However, it appears that the .option command is not recognized, as JoSim returns the following message indicating that the OPTION control is not known and suggesting to consult the syntax guide for available controls.

Additionally, the V -1 command (as well as the more detailed V -3 option) does not seem to print the actual value of the seed being used.

Do you have any comments or suggestions on how this should be handled, or whether this is a known limitation or bug?

Best regards,
Luigi

Hi Luigi,

Please confirm that you are on verison 2.7 of JoSIM.

This feature was only added in the most recent version.

Hi Johannes,
No, thanks for your reply. I'm running the version 2.6.10, which I installed recently. Is there a way to update quickly or should I re-install everything?
I'm using Windows

Hi Luigi,

The latest releases are available here https://github.com/JoeyDelp/JoSIM/releases/tag/v2.7
Simply download the one for the operating system you are using and replace your old josim-cli binary with the one from the downloaded bin folder (make a backup if need be). That should be all that you need to do to update to v2.7

Thanks it works now!
