PADS-LOGIC is a new generation of Schematic Capture
software with many advanced, time saving features
not available with other systems.
PADS-LOGIC is equally suited to both analog and
digital design work.
Flexible output capabilities are provided so that
it can be linked to any workstation or PC based CAD
system as well as Logic Simulation or Circuit Analysis.
$$:3
PADS-LOGIC IS AFFORDABLE!
Ask your local reseller how competitively PADS-Logic
is priced. Now every engineer and designer can have
their own personal Schematic Capture system.
$$:4
PADS-LOGIC's powerful and unique features include:
A true Multi-Sheet Database. This means ALL the
sheets of your design are available concurrently
in memory--not merely a single sheet, as with most
systems.
With a Multi-Sheet Database, you can quickly
switch between all sheets of your design.
A Multi-Sheet Database allows on-line checking across
the entire design -- not merely a single sheet.
$$:5
Other features of PADS-LOGIC:
- Reference designators, gates and pins are
automatically assigned to your parts. You are
then free to spend your time designing rather
than on clerical tasks!
- Search and Query functions across the entire
design provide you instant access to any part,
sheet tag, signal name or other item in the
database.
- Group Copy of circuit blocks between sheets of a
design or to a different design is a great time
saver. Naturally, all copied components are
automatically renamed.
$$:6
MORE FEATURES:
- Large design capability: approximately 1000
14 pin equivalent IC's per design, on up
to 256 sheets.
- Powerful hierarchical capability with
unlimited levels.
- Sophisticated macro command language.
$$:7
AND STILL MORE FEATURES:
- A library of over 6,000 parts.
- Interfaces to most CAD systems.
- Interfaces to Logic Simulation and Circuit Analysis.
- Full ASCII IN/OUT for third party interfaces.

PADS-Logic + PADS-PCB = A TOTALLY INTEGRATED SYSTEM
PADS-PCB, our powerful low-cost Printed Circuit Board
design tool, shares not only the same user interface
with PADS-LOGIC, but also, a common library and library
database manager.
As a result, the PADS integrated design system supports
AUTOMATED ECO processing! Full forward and backward ECO
capability including gate and pin swapping, component
rename from pcb to schematic, and, automatic add/delete
connections, parts, and routes; plus, you can rename nets
and parts from the schematic to the pcb!
$$:8
MULTI-SHEET DATABASE
Let's now look at the practical advantage of
PADS-LOGIC's Multi-Sheet Database.
The arrow above points to the Sheet Data,
indicating we are currently on sheet 1 of a 2
page schematic. Watch how quickly we can access
sheet 2.........
$$:9
SEARCH and QUERY items across all sheets.
Let's SEARCH for component U7. PADS-LOGIC
automatically takes you to the appropriate
sheet and highlights your requested item....
$$:10
QUERY
Now, let's Query component U7.
Watch how PADS-LOGIC automatically displays a list
of each pin associated with the part along with
its pin type and attached signal name.....
$$:11
AUTOMATIC REFERENCE DESIGNATORS
Let's watch the automatic reference designator
module assign reference designators as three
resistors are added to the sheet.
$$:12
AUTOMATIC REFERENCE DESIGNATORS
Now let's add 3 integrated circuits.
$$:13
AUTOMATIC GATE AND PIN ASSIGNMENT
PADS-LOGIC, in addition to automatically assigning
reference designators, also assigns gates and pins.
Let's watch!
$$:14
TO SUMMARIZE:
PADS-LOGIC's Multi-Sheet Database can instantly
switch you between design sheets, and automatically
keep track of your reference designators, gates and pins!
Search functions instantly take you to your requested
item and Query provides critical information associated
with each part in your database.
With PADS-LOGIC's Multi-Sheet Database, you the
designer can concentrate on the design effort!
$$:15 blue white red
ALTERNATE DECALS
PADS-LOGIC provides the capability of changing the
current part symbol to an alternate representation
while the part is being located or placed on the
schematic. As an example, ALTERNATE DECAL can be
used to instantly replace the original part symbol
with the DeMorgan equivalent of the part.
WATCH..........................
$$:16
PARTS LIBRARY
The parts library provided with PADS-LOGIC is an
integrated CAE/CAD library containing the electrical
properties together with schematic symbols and
physical component information.
Over 6,000 versions of both digital and analog
parts are provided. A Part Editor is provided so
you can easily create or modify a part. This can
be accessed on-line at any time.
$$:17
ALSO.....
PADS-LOGIC allows you to define multiple
USER Libraries. You can have a dedicated
library for each logic family, i.e., TTL,
ASIC, PALS, Analog, etc.
AND
A Library Merge feature lets you easily
exchange parts with other designers!
$$:18 blue white red
POP-UP WINDOWS
Pop-up windows permit you to browse the files on
your design and the library.
$$:19
JOB FILES...........
$$:20
LIBRARY BROWSING
Watch how easy it is to scan a list of
components and select the appropriate part
for your application.............
$$:21
CONNECTIONS
Adding connections between the parts is
especially easy with PADS-LOGIC.
When parts are connected on the CRT, the
connectivity of the circuit is established
and a netlist is immediately available. Post
processing to convert the 2-D lines into
connections is not necessary, as is the case
with many systems.
$$:90
ON-LINE DESIGN RULES CHECKING (DRC)
Moveover, PADS-LOGIC's intelligent database
incorporates real time on-line DRC of
connections. A self-checking database
prevents wiring errors, eliminating the need
for time-consuming, tedious error correction.
$$:91
AUTOMATIC TIE DOTS
PADS-LOGIC automatically places tie dots.
Let's watch as the parts on a schematic sheet
are connected......
$$:22
Power and Ground symbols automatically tie the part
pins into the Power or Ground nets.
$$:23
OFF-PAGE SYMBOLS
Off-Page symbols automatically tie connections
located on different sheets into a single net.
$$:24
MODIFYING A CONNECTION
What if you change your mind about something
and need to modify the circuit?
With PADS-LOGIC, modifying existing connections
is easy.
WATCH..........
$$:25
SWAP PINS
PADS-LOGIC let's you
Swap Pins with any
component.
Watch how Pin 1 (E)
is swapped with Pin 2
(A0) on component U1A.
$$:26
SWAP PINS
Swapping pins is easy
with PADS-LOGIC!
$$:27
BUSES
Buses and their connections are especially easy with
PADS-LOGIC. The naming of individual data bit lines
is done automatically.
WATCH.........
$$:28
THE GROUP FEATURE
Group commands can be used to cluster together all or
some of the items in the sheet of your schematic drawing.
Once a group is defined, it can be moved, rotated,
deleted, mirrored, copied, and "cut" to the hard
disk and "pasted" for use in another design.
Watch as a group is created and copied in a step and
repeat fashion. The reference designators will be
assigned automatically to the new group.
$$:29
The group has been created.
Now it will be copied below
the original group. Notice
the new reference designators.
$$:30
The new reference designators
are assigned automatically and
can never conflict with
existing ones.
$$:31
MACRO COMMAND LANGUAGE
Macros are a powerful time-saving tool. They are
a collection of keyboard and mouse recordings
created by the designer to automate repetitive
tasks.
You can save considerable time capturing the logic
of your schematic by customizing macros with
PADS-LOGIC's powerful macro command language!
$$:32
REPORTS
Designers need constant and accurate information
on their design. PADS-LOGIC provides a complete
repertoire of reports. Moreover, with a true
multi-sheet database, these reports are instantly
available on-line. There is no need for cumbersome
post-processing and linking of multiple sheet files.
Let's examine a few reports....................
$$:33
BILL OF MATERIALS
The Bill of Materials can be completely
customized to your requirements.

ENGINEERING CHANGE ORDERS:
One of the most important features of any schematic
capture system is the ease and absolute accuracy
with which engineering changes are handled.
FORWARD ANNOTATION:
PADS-LOGIC permits you to make changes in the schematic
and these changes automatically update the printed
circuit board.
$$:40
BACKWARD ANNOTATION:
In some systems you cannot incorporate a change at the
printed circuit board level!
In PADS-LOGIC, changes like gate and pin swapping
that are made to the board are used to automatically
update the schematic.
$$:41
ENGINEERING CHANGE ORDERS:
Simply stated, changes made in PADS-LOGIC will
automatically update the PCB layout database.
Similarly, changes made in our PCB layout system
can automatically be transferred to PADS-LOGIC.
The results of the ECO process is a new database
that GUARANTEES the schematic to be electrically
identical to the board layout!
$$:45
HIERARCHY
Hierarchical design helps you organize your complex
schematics into more manageable ones.
PADS-LOGIC supports unlimited levels of hierarchy
using either methodology of top-down or bottom-up
circuit creation.
