Hi Austin -
For the large yellow box, edit the symbol in DEHDL and remove those lines.
The pin numbers will appear on the pin stubs when you back annotate the
schematic. Or, use the SECTION command and click on a pin stub - the pin
numbers will appear.
To "remove" the instance property - use the Display invisible command and click
on this Path/instance property. Or, you can type in the DEHDL console window -
Find Path
Display invisible 'A'
Or, better yet, on the symbol view itself, add a $PATH=? property and display
it invisible.
Anytime the part is added, the instance value will be invisible.
Hope this helps.
Jerry

Subject: [PCB_FORUM] Allegro Design Entry HDL (ConceptHDL) questions...
Hi,
I have a design that I am updating that is in Allegro Design Entry HDL.
I'm trying to learn how to create schematic symbols.
So far, I understand I have to manualy set-up a directory in a library
directory with the part name as the directory name and with subdirectories
"chips" and "part_table". Then, I create a file "chips.prt" in the chips
directory copying one from an existing symbol, and modifying it. And, a
file "part.ptf" in the part_table directory, again, copying one from an
existing symbol and filling it in.
Then, I create the graphics by copying another graphic, and "save as" into
this new directory in a subdirectory "sym_1".
I can add the new symbol to the schematic. But, I have a couple of
"problems". One is in the add component, the graphics shows a large dashed
yellow box the size of the old symbol. How can I change that?
Second is, when I put the symbol on the schematic, no pin numbers show up.
How do I get the pin numbers to show up?
A general schematic question...when I copy a symbol, or add one, the
instance number shows up. It's not visible on any of the pre-existing
symbols. How do I get that to be invisible?
Any help greatly appreciated!
Austin
