Pcell, Label and orientation.

[bu-bu]

Hello !!

I have a small question...

With "[@instanceName]", i can display the name of my pcell.

Is there a command to extract the orientation of my pcell ? I would
like my labels to be easily readable if i rotate it...
Just to avoid stiff neck.

Thanks and regards,

b.

Pcells should never try to look up information about how they are instantiated,
except via the parameters that are passed in. There is a way of doing it, but it
will only lead to incorrect behaviour. In essence, the only thing that triggers
the pcell code to be evaluated is a change in the formal pcell parameters.
That means that the code for two instance which have the same parameters but
only differ in orientation will only get called once - so if you tried to
figure out the orientation of a label based on instantiation, it would simply
use whichever got instantiated first. Bit of luck, really, as to which that
would be - so it's a BAD idea.

Regards,

Andrew.
