There are several tutorials shipped with all versions SynaptiCAD's software. These tutorials demonstrate
everything from how to draw basic timing diagrams to advanced VHDL and Verilog simulation techniques.
After installing one of SynaptiCAD's products, choose the Help > Tutorials menu
to open the tutorial help page. Each tutorial can be printed by using the print command in the help
window. Below are summaries and links to PDF versions of each tutorial. Please note that the TestBencher
Example tutorials are installed in the SynaptiCAD\Examples\docs directory rather
than under the Help menu.
Timing Diagram Editing Tutorials
Basic Drawing and Timing Analysis Tutorial
demonstrates the basic timing diagram editor features. It teaches you how to draw timing
diagrams using delays, setups, clocks and part libraries and how to use timing diagrams to help
detect timing errors in digital designs. It also covers the waveform editing features, measurement
and quick access buttons.
The Simulated Signals Tutorial
demonstrates how Simulated Signals reduce the amount of time needed
to draw and update a timing diagram, because the
waveform is described using a Boolean or registered
logic equation. With Simulated Signals you will no
longer have to figure the output of a combinational
circuit or calculate the critical path of a
synchronous circuit by hand. WaveFormer Pro has an
internal interactive simulator that supports
multi-bit equations with true min-max timing, unlike
traditional simulators that can only represent
single-valued delays. This tutorial contains some
simple examples of Boolean and registered logic
equations that showcase the simulator's
The Display and Documentation Tutorial
introduces techniques for controlling the display of
parameters, clocks, waveforms, markers and text
objects. These techniques will allow you to control
exactly what your timing diagrams look like and what
information is displayed.
The Analog Signals Tutorial demonstrates
how to easily create and display analog waveforms
with the mouse, and generating with waveform and
explains how to create and use timing parameter
libraries. Library files contain the timing
parameter information for circuit components.The
timing diagram editor can be used to create
libraries with parameters that are exclusive to your
projects. The timing diagram editor also ships with
several standard libraries that contain over 10,000
timing parameters, and it also supports the industry
standard TDML on-line component information.
The Advanced Modeling and Simulation Tutorial
demonstrates how WaveFormer Pro can
quickly model and simulate a digital system of
moderate complexity. We will be modeling a circuit
that computes histograms for 64K of data generated
by a 12-bit Analog-To-Digital converter (this is a
popular method for testing dynamic SNR for ADCs).
This circuit is a simplified form of a real VME
board that would take several months to model and
simulate using conventional EDA tools. Using
WaveFormer, we will model and simulate this
simplified circuit in 20 minutes. The full circuit
with the complete VME bus interface protocol could
be modeled and debugged in about 4 hours.
Test Bench Generation Tutorials
The Advanced HDL Stimulus Generation Tutorial
describes how to generate Verilog and
VHDL basic stimulus test benches using WaveFormer
Pro, VeriLogger, Reactive Test Bench Option, and
TestBencher Pro. It explores how different waveforms
and state values in a timing diagram will affect the
generation of the test bench code. It also explores
the SynaptiCAD language-independent signal types
which allow a single timing diagram to generate both
VHDL and Verilog test benches.
The Reactive TestBench Generation Tutorial
demonstrates the Reactive Test Bench Generation Option which can be
added to WaveFormer Pro, DataSheet Pro, VeriLogger,
and BugHunter Pro. The features are included in
TestBencher Pro, so it is also a good introduction
to creating a single timing transaction in
TestBencher Pro. With Reactive Test Bench
Generation, users can draw "expected" waveforms on
the MUT output ports and add "samples" to the
waveforms to test for specific state values. During
simulation, the code generated by the samples would
watch the output from the model under test and
compare it to the drawn waveform states. Samples can
perform a variety of functions such as pausing the
simulation to debug a problem, reporting errors and
warnings, user-defined actions, and triggering other
TestBencher Pro: Basic Tutorial covers the basic concepts
of using TestBencher Pro to generate bus-functional models for Verilog and VHDL. It covers
signal properties (type, direction, vector size, and bi-directional segments), samples, parameterized
state values, end diagram markers, interface diagrams, modifying top-level template files, and generating
test benches. TestBencher Pro users should do this tutorial.
TestBencher Pro: AMBA Example demonstrates how to create and use an
AMBA AHB master. It makes extensive use of Pipeline Boundary Markers in the master transactors which
are used to model the pipeline behavior defined by the AMBA specification. "Blocking Samples" in the
master write and read transactions are used to wait for HREADY. Loop Markers in the master idle and
busy transactors insert variable number of idle or busy cycles. State Variables and "Store Sampled Value
As Subroutine Output" variables in the master write transactor are used to pass the read data back to
the sequencer process. There is also a User-defined Class Method that determines the burst length based
on a given burst code (defined by AMBA spec.). And finally the project makes use of Constrained randomization
so that idle and busy transactors are applied using a random number of idle or busy cycles.
TestBencher Pro: PCI Example demonstrates how to create PCI master and
PCI slave bus-functional models (BFMs) using TestBencher Pro. These are not 100% complete BFMs that
can test every feature of the PCI protocol. Instead, they are just partial BFMs to help in the understanding
of TestBencher Pro. Each BFM is modeled using a TBP project, which is then instantiated in another project
named PCI.hpj. This an excellent example of hierarchical model design how the user can specify ports
of slave and master BFMs using the Component Signals & Ports dialog. Some features used in this example
include: loop markers, wait until markers, HDL code markers, state variables, simple expect samples,
blocking & non-blocking samples, and user defined samples..
TestBencher Pro: Pipeline Example demonstrates how pipelined transactors
can be created and how they work. To create the pipeline phases, "Pipeline Boundary" Markers were placed
on each clock edge that starts and/or ends a pipeline phase. For each "Pipeline Boundary" Marker that
starts a phase, a semaphore name is specified. This is done in the "Edit Marker" dialog and can be any
valid identifier. To indicate the end of the last pipeline phase, you can either select "End Boundary"
as the semaphore name or create an "End Diagram" marker.
TestBencher Pro: UART Example demonstrates how to design a Universal
Asynchronous Receiver/Transmitter (UART) controller which is the key component in serial bus communications.
The UART takes bytes of data and transmits the individual bits in a sequential fashion. At the destination,
a second UART re-assembles the bits into complete bytes. This project contains three transactors: CLK_generator,
WriteSerial, and ReadSerial. In this example, the WriteSerial and ReadSerial transactors communicate
with each other. They send and receive serial data on a signal named UART. But, they work with parallel
data at the transactor level. For example, the write transactor has an eight bit argument which it then
converts to serial data. Both of these diagrams also have a parameter named "speed" which controls how
many clock cycles are to be used for each bit of data.
TestBencher Pro: VME Example demonstrates how you would create bus-functional
models (BFMs) for the arbiter, master, and slave VME components. It also shows one way to configure
a set of slave BFM instances to respond to different address ranges. Each of these BFMs are represented
by a TestBencher Pro project which are all instantiated in a top-level project named VME.hpj. This entire
example is composed of unclocked diagrams.
Basic Verilog Simulation
demonstrates the basic simulation features of the
VeriLogger simulators (simx and vlogcmd) and the
graphical debugger (BugHunter Pro). It teaches you
how to create and manage a project and how to build,
simulate, and debug your design. It also
demonstrates the graphical test bench generation
features that are unique to BugHunter Pro.
Optional Feature Based Tutorials
is an optional module that can be added to most of
SynaptiCAD�s products that have a waveform editing
window. This feature allows comparison between two
timing diagrams or between individual signals in a
timing diagram. The results of two simulation runs,
or of logic analyzer data and a simulation run, can
be compared very easily using this feature.
Gigawave and WaveViewer Viewer Tutorial
covers the following topics: opening a
waveform file, the differences between opening and
importing a file, saving a .btim file, creating a
filter file to selectively load sets of signals from
a waveform file, and available licensing options for
Transaction Tracker Tutorial
explores semantic differences
between some of the most commonly used PSL
operators. The assertions in this tutorial
have been kept very simple, so that it is easy
to see the differences between the operators.
It is important to understand these
distinctions before attempting to write
practical, real world assertions.
Evaluators: If you are evaluating the product we recommend that you do at least the General Design tutorials.
These will give you a good idea of the flexibility of the product. If you design in VHDL or Verilog
you should also look at the HDL tutorial and the TestBencher tutorial and examples.
