Technology definition from command line

stolbikov

Hi Matthias,

I have adjusted the list of technologies I use through "Technology Manager".
For example, one of them is named "MYTECH".
Then I run KLayout with technology defined from command line like:
$>klayout -n MYTECH test.gds
In this case technology data is loaded OK but the technology name is not changed on the "T" button and remains (Default) and Default technology is marked in dropdown menu.
It slightly confuses. Is this a bug?

Thank you.

Matthias

Hi,

well ... that's probably how you look at it.

Basically the "T" button does not reflect the technology loaded but is supposed to assign a technology.

The concept is that each layout has a technology attached. The technology attached to the currently selected layout is indicated in the "T" status bar label at the lower left corner of the main window. The "T" button will change the technology. So basically the connection between the "T" button in the tool bar an the technology is one-way only (I tried to make it two-way as you expect, but that was not without strange side effects, so I dropped that idea).

When you use "-n" you will change the technology assignment (check that in the status bar), but the button in the tool bar will still reflect your choice of technology and when you push it you will change the technology of the layout accordingly.

Hope that explanation helps.

Regards,

Matthias
