Carson, CA (December
-- Intusoft announced today the first release of "DSP Designer,"
a novel approach to developing digital control and digital signal processing
(DSP) functions using the IsSpice4 simulator inside several of Intusoft's
ICAP/4 suites and Test Designer product.
DSP Designer is a
revolutionary breakthrough to DSP development. The new capability enables
digital control algorithms to be visually simulated using special device
models to create and simulate Z transformations and corresponding DSP
programming instructions, including hidden parameters not accessible within
usual DSP design. Results are viewed as waveforms and Bode plots, enabling
the designer to grasp a visual correlation of the DSP's micro-code and
design performance. Other aspects of a DSP can be simulated such as digital
and analog signal conversions, sample/hold, filtering and load. DSP Designer
is also valuable for verifying design accuracy and performance if assembly
code instructions are manually entered through an integrated development
system, as is traditionally done.
DSP Designer: A Novel Approach
offers a breakthrough in eliminating the tedium and error-prone assembly
language programming of DSP. Intusoft's ICAP/4 simulation framework employs
functional blocks and fast "average" models to create Z transforms
for simulating DSP digital control. The models perform synchronous switching,
which simplifies the SPICE model and always performs in a continuous conduction
mode (CCM). DSP Designer enables large-signal line and load transient
analysis, start-up analysis and noise injection for predicting EMI, as
well as provides built in self-test (BIST) when used within Intusoft's
Test Designer product.
Larry Meares, founder and chief engineer at Intusoft positioned: "It's
a known fact that programming assembly-language instructions for DSP is
very tenuous, also allowing mistakes to be passed through without detection.
The engineer can now accurately create transfer functions and verify the
results, prior to passing on equivalent coding instructions." In
the near future coding from DSP Designer's IsSpice4 simulator will be
automatically converted to assembly language format, inputting that data
through an integrated development interface (IDE), which feeds into the
DSP development board's memory. DSP Designer includes a firmware plug-in
that enables signals from Tektronix series 1000 and 2000 oscilloscopes
to be viewed directly in ICAP/4's "IntuScope" waveform viewing
tool, alongside equivalent simulation waveforms. Several design examples
and technical DSP articles are accessible from Intusoft's website, and

Intusoft's marketing director, Tim Ghazaleh, commented: "The DSP
marketplace had a reported $7 billion presence in 2007. In response to
this we're evangelizing a groundbreaking approach to DSP, making the development
and programming of DSP systems easier for both digital and analog designers."
DSP Designer is ultimately slated to work with a development board designed
by Intusoft in Q1, 2009. This would work in conjunction with select DSP
boards from MicroChip Inc., Texas Instruments and possibly others.
DSP Designer is included in several of Intusoft's higher-end simulation
packages, whose upcoming release will also be in December, 2008. DSP ICs
are used in the majority of digital phones, and increasingly are found
in several electronic and energy end-use markets.
reference account program offers its customers no-cost and reduced-cost
upgrades to DSP Designer in exchange for their evaluation and work with
the software package. The program will also be open to new purchasers
of DSP Designer.
