Artist global net question

[Sylvio Triebel]

I'd like to access some global nets, which are defined in a sub-block.
If this would work, we wouldn't need to create for every case a new symbol with additional pins...

Unfortunately, Artist recognizes some "conflict" and maps all global nets used in sub-blocks, which
are also used at the top level to a new name (e.g. _net0, _net1...).
So, it is probably a netlister issue.

Is there any option in Artist to disable this 'intelligent' behavior?

Or... is ther something i have still to do if I define global nets in a cell view.
I thought, that a '!' at the end of the net name is sufficient...

For my understanding global nets should be global and accessible from every hierarchy level.
Only the name should be unique...

Thanks for any ideas...

Hi all,
I already solved the problem.
Keep in mind, that in a CDB cellView the attribute isGlobal of signal database objects
is relevant to define a net as global... not the "!" at the end of the net name!
In a schamatic "Check And Save" will set this attribute automatically.
In an av_extracted view e.g. however - you need to set the isGlobal flag as an
extra step. Then the netlister will work as expected...

Ciao, Sylvio
