WHAT DOES ICAP/4 PROVIDE THAT COMPETITIVE OFFERINGS LACK?
Enhancement to a SPICE kernel (i.e., SPICE 3F5, XSPICE) is an unequivocally
important aspect in providing a truly robust analog and mixed-signal
simulator. SPICE kernels that have not been significantly modified often
fall short on tough design such as switch mode circuitry, oscillator,
time-varying control loop and large-scale topologies. It requires several
years to successfully augment SPICE technology, for which Intusoft continues
to invest its resource (i.e., advanced convergence algorithms: ICSTEP,
VSECTOL, AUTOTOL). This investment has also enabled Intusoft's free
custom modeling service to model complex ICs, originally thought not
possible by requesting engineers.
Schematic to Waveforms:
During an active debug cycle the engineer cannot always ascertain what
design nodes to plan on setting waveform markers for viewing. Therefore,
the ability to arbitrarily probe around the schematic following a simulation
run and instantaneously view waveforms is a tremendous time saver. Waveform
views are brought into the IntuScope waveform viewer or directly placed
on the schematic. Update for existing waveform views is a one-button
operation and selectable in three different modes: update plot, create
new plot, or add to plot.
component sweeps: This rare and valuable feature has been
with the ICAP/4 offering for many years because of the time it saves
during design debug. Component parameters can be set to a value, continuously
changed by pushing a button, or set as an expression, all with no schematic
intervention. Simulation results are displayed as simulations run.
and temperature variation in Models:
When designs rise to high frequency operation, frequency can influence
the modeling accuracy of passive components. ICAP/4's ability to program
passive devices to accommodate frequency and temperature variation helps
ensure truer design accuracy.
