UL_BOARD Signal Names for Module Instances [message #165098] Sat, 06 February 2016 21:00 Go to next message

Hi,

I'm running v7.5 and having trouble with a ULP. I'm iterating with
B.signals(S) in a board and the name it reports with S.name doesn't seem
to include the the module prefix for module parts. In other board files
I did the name appears with module prefix and colon (eg, "BUF4:N$7").
Not sure if this has changed from a previous release, but was wondering
if any has any idea why the module name prefix is missing. I'm working
on a ULP that duplicate routing for module instances and just noticed
this problem recently.

Thanks,

Bob

Hi Bob

Maybe the issue you are running into is the one where:
If the module net connects a net outside the module it gets renamed to
the name of the one outside the module. After all you cannot have two
connected nets with different names.

Using v7.5 win7 I get the correct format for nets within the module but
not connected to nets the outside of the module

e.g.
FILTER1:GND (port not connected elsewhere here)
FILTER1:N$1
FILTER2:GND (port not connected elsewhere here)
FILTER2:N$1
INPUT
OUTPUT

INPUT and OUTPUT are the net names outside the module so the module nets
I don't see now are .
FILTER1:IN
FILTER1:OUT
FILTER2:IN
FILTER2:OUT
