Design Clarity
SEE THE FUTURE OF YOUR CIRCUIT DESIGN
SPICE
ANALYSIS using DESIGN MASTER
GENERAL
-General review of circuit
performance
-Similar to prototype testing
-Schematic input
WHY DESIGN ENGINEERS SHOULD AUGMENT
THEIR SPICE SIMULATIONS WITH ANALYSIS
-Thorough review of circuit
performance
-Similar to spreadsheet
analysis
-Designer-friendly equation
input
DESIGN INSIGHT
-Inferred by reviewing waveforms
-Users must be careful to avoid "cut and try" design hacking
-Equation-based format
enhances understanding and
spurs creativity
WORST CASE PERFORMANCE
-Monte Carlo provides an
estimate of tolerance
stack-up
-Worst case performance
limits are explicitly identified,
including a probability plot…
-…and waveforms are also
provided to compare to SPICE
and lab results
OPTIMIZATION
-Some SPICE programs can vary a parameter while other conditions remain fixed
-A table of Normalized
Sensitivities and Optimized
Values provides instantly usable
optimization data for all
variables, taking into account the
combined effects of all
tolerances
RISK ASSESSMENT
-Not quantified; may be roughly inferred from the Monte Carlo output
-The estimated probability of
exceeding specification limits
(ALERT) provides a rational
basis for pass/fail, and is much
more cost effective than using
worst case results alone.
HANDLING NONLINEARITIES
-Straightforward, but reasons for anomalous performance may be obscure
-Nonlinear effects can be readily incorporated into equations; e.g. IF-THEN-ELSE statement.
OUTPUT
-Plots similar to test equipment readings
-Plots similar to test equipment
readings, or for any desired
equation
-Min/Average/Typical/Max
performance
-Probability plot
-Normalized sensitivities
-Optimum values
-Comprehensive Word document report
MISCELLANEOUS
-Numerous standard device
models are available
-Numerous standard analysis
circuits are available
-Splits complex equations into
easy-to-visualize smaller
sub-equations
-Most performance can be
analyzed with algebra or simple
calculus
-Models can be generated to
facilitate advanced calculations
-Solves circular references such
as feedback loops
-Handles complex variables; e.g.
filter analysis
-Advanced design/analysis
packages available to
Professional Edition subscribers
