This video is taken from the INT 100 course on Ansys Innovation Courses.
The basic workflow when designing a circuit in INTERCONNECT begins with adding the schematic
circuit elements, and setting the properties of the elements.
For example, you can add a waveguide element and set the properties that characterize the
waveguide such as the length, effective index, group index, and dispersion.
Many common generic circuit elements, like waveguides, phase shifters, splitters and
so on can be added from the built-in Element Library.
In a later section of the course, we will discuss how to add your own circuit elements.
Next, decide the solver type that you want to use.
This can either be the frequency domain solver, to get the steady-state response of the circuit,
or the time domain solver, if you want to get the transient response.
Based on the type of solver, you can add the corresponding sources, detectors, and analyzers
for that type of simulation.
For example, for a frequency domain simulation, you can use an optical network analyzer, also called an
ONA, to get the transmission spectrum from a circuit, whereas for a time-domain simulation,
you can specify a source with time-varying signal, and use an oscilloscope to measure
the output over time.
Once all of the circuit elements, sources, analyzers and detectors have been added, and
the connections between the elements are wired up in the circuit schematic, you can run the
After running, the simulation is switched from layout mode to analysis mode where analysis
can be performed by plotting results from analyzers and detectors, exporting data, and
using the script to collect and perform post-processing of the data.
Based on the analysis, you may want to modify the circuit design.
You can also switch to layout mode to make the desired changes, and re-run the simulation.
The next unit will introduce the circuit layout editor.
