Eclispse for Windows is an unparalleled RF/Microwave linear simulator
for the PC platform. The program uses a unique tabbed-notebook interface
with "drag and drop" capabilities for building netlists and graphical output.
The element library includes a wide variety of lumped, distributed, active
device, microstrip, stripline and control-block models. Eclipses features
include:
Comprehensive Element Library Resistors, inductors and capacitors
(ideal/lossy, self-resonant), reactances, complex impedances, dependent
sources, ideal transformer, multiport blackbox devices (S, Y, Z-parameters),
port terminations (impedance, gamma or black box), transmission lines,
coupled lines, attenuator, transformer, control blocks (summing,
integrator, differentiator, pole, zero, gain), bipolar, FET and diode
semiconductor models, microstrip and stripline structures.
Element Assistant Eclipse's unparalleled Element Assistant makes remembering
element parameters completely unnecessary. Click the right mouse button on
an element in the netlist and the Assistant pops up with data fields clearly
labeled for all element parameters. Each field displays context sensitive help
with full on-line documentation a mouse click away.
User-defined variables provide powerful input and output processing
capabilities. This powerful feature lets you combine constants, Program
Variables (such as Y, Z or S-parameters, gain, current frequency, etc.),
Program Functions and other User Variables into interrelated complex
mathematical expressions. Once defined, your "programmable" User
Variables can be graphed or used as element parameter inputs.
Flexible Sweep Capability You have complete control over circuit stimulus and
output processing through Eclipse's project notebook. Each page contains its
own definition regarding how the circuit is to be swept. Eclipse can sweep a
circuit by changing the frequency, an element parameter or User Variable.
Element sweeping allows you to directly vary any single parameter of any
element over a chosen range of values at a single frequency. Variable
sweeping allows you to similarly vary a User Variable; however, since User
Variables can be assigned to element parameters, elements can be indirectly
varied as well. The possibilities are limitless.
Manual Element Tuning Rapidly tune multiple elements and/or User Variables
using standard EIA increments (1%, 5% and 10%). Independent save/recall
registers are available for intermediate storage of tuning values.
Optimization Use Eclipse's powerful optimization features to automatically
minimize the difference between desired and actual circuit performance.
Performance goals are formulated in terms of mathematical expressions
comprised of Program and/or User Variables. You can mix relative as well
as absolute specifications when defining goals. Eclipse's summary box will
show you the contribution of each goal to the overall error.
Output Parameters S, Y, Z-parameters (1 to 4 ports), Maximum Available Gain,
group delay, voltage gain (three types), Series or Parallel impedances
(reactance displayed as ohms, inductance or capacitance), Stability Criteria (K,
Rs_min/Rp_max for guaranteed stability). Output can viewed in graphical or
tabular form.
Network Analyzer-style Markers Eclipse provides four independent markers
for each graph. Each marker's X and Y values are automatically tracked and
displayed during simulation, tuning and optimization. Various marker functions
are available to enhance displayed information.
Custom Graphs Just right mouse click on any graph to independently customize
its appearance using the Graph Properties dialog box. For instance, with the
Autolines feature you can define additional boundary lines to be drawn on
each graph. Save traces to memory for comparison with "live" data or enable
Eclipse's history feature to dynamically retain and display up to 5 of the most
recent traces.
Industry Standard Data Files Data files may be imported/exported in industry
standard format.
Power Comprehensive element library, programmable user-variables, unlimited
graph sheets, multiple sweep types, manual tuning, optimization, custom
graphs, complete on-line help, project notes - it all adds up to raw power.
Productivity Intuitive notebook interface, drag and drop objects, context
sensitive pop-up menus and object properties dialog boxes - not only will
you get it donefast but you'll have fun doing it.
