Can not update pcell masters

Ilya Temnikov
Ilya Temnikov over 10 years ago

Hello

When I want to redraw all the masters of pcells I do something like this:

foreach(c dbGetOpenCellViews()

when(c->isParamCell

dbPurge(c)

)

)

And Virtuoso regenerates all the pcell masters

But I've got a library that contains python pcells. And this doesn't work here after pcell updates. I see that the supermaster is updated but the instance continues to behave like there were no any changes. The changes take effect after Virtuoso reloading only.

The question is how to force Virtuoso to redraw python pcell masters without reloading Virtuoso session?

    Ok. But maybe there is a possibility to change an environment of current Virtuoso process? For example if I execute sh("export my=1") from CIW commant line then it starts a new process and of course if i try to execute getShellEnvVar("my") it returns "nil". But I want this to return "1". Is there any possibility to change the current Virtuoso environment?
