PROTEL 2004 - BUS Multiply

Could anyone let me know a valid syntax using "REPEAT" keyword to
multiply a Bus in a multi channel schematic design (PROTEL 2004)?

A "REPEAT (BUS [1..4])" Entry Sheet in Parent will not make
vertical connection with a BUS[1..4] Port on Child Sheet. It generates
errors.

Cora,
So I see you are using DXP, well I am not so you have me at a
disadvantage but I went to the link you supplied to see what you
were seeing.

This "instantiation" issue is certainly new to DXP, I have
never heard the term used before. However, reading the
description they supply I think I have a good idea of what they
are doing. Usually in the past we drew one schematic of the
daughter sheet and it had multiple iterations linked through
multiple sheetsymbols on the parent sheet. Seems this new system
uses only one sheetsymbol on the parent sheet with this "Repeat
keyword" you are trying to define. Then each daughter sheet gets
X number of tabs, one for each repetition of the circuit.

Ok, this is not so different than the good ole system only
the schematic appears in one sheet instead of X number of virtual
sheets below the parent. Then the one singular sheet has tabs to
switch designators appropriately for each circuit repetition.
That is my take on it anyway, new spit and polish for the old
system. It is all fluff!

As far as I can see the key word is a function that is built
into the sheetsymbol on the parent schematic sheet. I would think
that there is a keyword "Repeat" accessible for a sheetsymbol. Or
you must add the keyword into the sheetsymbol some how.

As for the ports, your original question, I don't think they
are special in any particular way. Port AD[0..8] on the daughter
sheet connects to port AD[0..8] on the parent sheet. There is
nothing special about the port naming from what I can see, use
the same conventions as one has always use for ports and
sheetsymbols. The repeat seems to come from the Sheetsymbol and
adding (or setting) the Repeat keyword for the sheetsymbol.

I did some checking on the DXP website, lo and behold I found the
following tutorial for multi-channel designs:
http://www.altium.com/learningguides/dxp/tu_dxpmultichannels.pdf
Check page 3, points 3, 4, 5 & 6. I was right it is a keyword of
the sheetsymbol.

Thanks for feed-back Brad.

I'm back with some extra details for you guys:
I drawing just schematic ( no VHDL, no Spice), but using multi
channel
design concept. The whole idea is to nest and repeat an entire
sheet in
other in order to simplify schematic and also PCB design.
Concept
it's come exactly to avoid multiple copy -paste.

Take a look to "True Multi-channel Design" Bookmark on

http://www.altium.com/learningguides/dxp/dxp_featurehighlights.pdf

Altium provide a simple example describe on TU0112 Creating a
Multi-channel Design but it don't show syntax to repeat an
entire
bus. Let suppose in this example that I need Bus P[1..8]
and/or
K[1..8] link out the sheet (Bank.SchDoc ) via a Port and get
repeated
four times in Parent sheet ( Detector.SchDoc ). What syntax I
should
have for correspondent Sheet Entry of REPEAT(PD,1,8) Sheet
Symbol?

By the way, If I try to compile this multi channel design
example,
witch come with PROTEL 2004, I get following errors:
Duplicate Net
Names Bus Slice K[1..8], Duplicate Net Names Bus Slice P[1..8],
Wire
Net Label OFF at 420,610 placed on a bus.
I don't understand why.

Cora_7,
I had previously seen your post to the PEDA listserver. I
am
not sure that anybody understands what you are trying to do.
If
you didn't get an answer on the PEDA list then you are in
uncharted territory or you have defined your problem in a
manner
that others don't understand.

Are you just drawing a schematic or are you doing some
VHDL,
SPICE or other detailed code type input? A schematic on it's
own
doesn't have a repeat function, other than the good ole
fashioned
copy and paste. So I think you have people lost and wondering
what you are doing.

Just by what you have written below, I would say that you
just drop the "REPEAT", do away with the brackets and your
bus
would connect fine between sheets, just make sure that the
netlist generator has the desired net and port configuration
for
your design hierarchy. Don't know where you got the "REPEAT"
from.
