WinS Examples list
Please consider that some of the examples are valid only for latest version
of WinS.
The example files also can be found in the folder "..\wins\examples"
after installation (see also Examples in help). WinS automatically starts in
this directory, thus these files can be seen in the "Open file"
dialog.
- Monitorp.sch shows the use of IV (average phase) and digital monitors.
This example is based on two-junction interferometer. Open "Display"
window to see result of simulation.
- Average.sch is an example of use the average voltage monitors with
different average times.
- Monitorv.sch shows the use of voltage monitors. This example is based
on two-junction interferometer. Open "Display" window to see result
of simulation.
- Monitorc.sch shows the use of current monitors. This example is based
on two-junction interferometer. Open "Display" window to see result
of simulation.
- Progcurs.sch illustrates the programmable current source use in the
regime that produces current steps.
- Progcurp.sch illustrates the programmable current source use in the
regime that produces current pulses.
- Voltage.sch contains two voltage sources with the different internal
resistances. This resistance should be taken into account when the low
resistance load is used. WinS
uses this internal resistor and two currents to perform this source. The rvoltage.sch
shows the equivalent circuit of the voltage monitor (or how it is presented
internally).
- Phase.sch demonstrates introducing magnetic field (or phase) into
two-junction interferometer with the phase source. WinS uses for this element
the inductor and two currents that is shown in the equivalent circuit
presented in iphase.sch example.
- Flipflop.sch is an example of digital monitors used in margins
simulation and optimization of the RSFQ T-flip-flop. Display window shows the
right operation margins of the circuit with the cursors positioned at the
point where circuit will be tested during margins calculations and parameter
optimization. Open logic window to see stored margins.
- Avoltage.sch and Fmonitor.sch are examples of the average
voltage and frequency monitor used in margin calculation.
- DCtoSFQ.sch is a
DC-to-SFQ converter. See logic window for margins.
- SFQtoDC.sch is a T-flip-flop with SFQ-to-DC converter. It is a good
demonstration of the frequency monitor used in margin optimization. Open logic
window to see stored margins.
- Avsfq_dc.sch is a T-flip-flop with SFQ-to-DC converter. It is a good
demonstration of the average voltage monitor used in margin optimization. Open
logic window to see stored margins
- Ivcurve.sch is an example of using IV monitors for IV calculation.
Ivp.sh
shows how the other parameter than the bias current can be used for
parameter-V curve.
- Nrjunctn.sch shows IV curve of the junction in nonlinear resistive
model with voltage gap and hysteresis.
- Sin.sch demonstrates functionality of the current function generator
and also how to calculate rf induced steps in IV curve of the junction.
- Long_jtl.sch demonstrates hierarchy, and
subcircuits. It is based on
50 junctions JTL and demonstrates the SFQ repulsion effect.
- Cvc.sch is an example of the external parameter used to take
subcircuit parameter for IV simulations.
- JTL.sch is an example of the Josephson Transmission line packaged into
the single element.
- PTL.sch is an example of passive transmission line packaged into the
single element.
- Ljj_zfs.sch - illustrates the first and the second zero magnetic field
Fiske step (IV-curve).
- Ljj_ffs.sch - Flux flow step at magnetic field corresponding
b
e=2.5 (IV-curve).
- Ljj_hfs.sch - Flux flow step position at gamma=0.5 as function of
magnetic field (IV-curve).
- Ljj_v.sch - Instantaneous voltage along the long junction
(LJJ voltage
monitor).).
- Ljj_p.sch - Instantaneous phase along the long junction
(LJJ phase
monitor).
- Ljj_t.sch - Shows how fluxons move in Long Josephson junction.
(LJJ
fluxon tracks monitor).
- LJJ_ALL.sch - demonstrates the use of the monitor graphic window
- AllPar.sch shows how to set other than first parameter of the element into the optimization list.
- ExtPar.sch is a demonstration of using subcircuit for margins and optimization.
- Psquid.sch is a comparison of two SQUIDs, one without pi-junction, and another one that contains normal and pi-junction. Voltage-magnetic field curves were simulated.
- Pjtl.sch demonstrates the effect produced by adding one pi-junction to
JTL.
- Pflipflop.sch demonstrates RSFQ toggle flip-flop operation. Flip-flop cell uses two pi-junctions and does not require magnetic field bias current. There is also no need for relatively big storage inductance because of the pi-junctions use.
