probe context?

What is a probe context and how can I find out
what information is stored in it? How can I use
the probe context?

When I do the following Cadence crashes:
deGetProbeContext(hiGetCurrentWindow())->probe

Where is the probe information stored? That is,
where does geGetAllProbe get its information? I
assume from the window?

If the probe information is stored with the window
then why is it that when I open 2 windows for the
same schematic and probe a net, that net is probed
in both windows?

 

Erik,

The probe context is a data structure used to store the context (i.e. the
design hierarchy information) that probes are created using. It looks as if it
is not intended to have any data access slots - and accessing any slot causes
it to crash.

I see a PCR has been filed for this, and I believe the fix will prevent it
crashing. I don't think the fix will allow you to see any information
associated with the probe context.

Essentially the probing system keeps stuff in its own internal (C level) data
structures, and some of that is made available to the corresponding SKILL
objects (probe objects have some slots providing information about the probe).
This idea is true of many objects implemented in DFII; some data structures
exist, and then SKILL accessor methods are provided to allow you to see some
(or all, or none) of the aspects of these underlying objects.

Andrew.
