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.

  1. 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.
  2. Average.sch is an example of use the average voltage monitors with different average times.
  3. Monitorv.sch shows the use of voltage monitors. This example is based on two-junction interferometer. Open "Display" window to see result of simulation.
  4. Monitorc.sch shows the use of current monitors. This example is based on two-junction interferometer. Open "Display" window to see result of simulation.
  5. Progcurs.sch illustrates the programmable current source use in the regime that produces current steps.
  6. Progcurp.sch illustrates the programmable current source use in the regime that produces current pulses.
  7. 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).
  8. 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.
  9. 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.
  10. Avoltage.sch and Fmonitor.sch are examples of the average voltage and frequency monitor used in margin calculation.
  11. DCtoSFQ.sch is a DC-to-SFQ converter. See logic window for margins.
  12. 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.
  13. 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
  14. 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.
  15. Nrjunctn.sch shows IV curve of the junction in nonlinear resistive model with voltage gap and hysteresis.
  16. Sin.sch demonstrates functionality of the current function generator and also how to calculate rf induced steps in IV curve of the junction.

  23. Ljj_hfs.sch - Flux flow step position at gamma=0.5 as function of magnetic field (IV-curve).
  24. Ljj_v.sch - Instantaneous voltage along the long junction (LJJ voltage monitor).).
  25. Ljj_p.sch - Instantaneous phase along the long junction (LJJ phase monitor).
  26. Ljj_t.sch - Shows how fluxons move in Long Josephson junction. (LJJ fluxon tracks monitor).

  28. AllPar.sch shows how to set other than first parameter of the element into the optimization list.
  29. ExtPar.sch is a demonstration of using subcircuit for margins and optimization.
  30. 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. 
  31. Pjtl.sch demonstrates the effect produced by adding one pi-junction to JTL.
  32. 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.
