In the System Architect, the designer can design its architecture using different blocks representing different circuit models, extracted from the DEVICE MODELER. A palette of control blocks (signal sources, probes, waveforms, spectrum, DC supplies, Simulation controls…) are available to run a time-domain simulation and assess the overall response.

For architectures with many circuits, as for active antennas, the schematic editor allows the description of the system at different hierarchical levels, making it possible to represent a set of circuits by a single element. For example, a block can represent several hundred amplifiers, simplifying the representation of the system greatly while offering the possibility of carrying out a fine and individual analysis of the behavior of each circuit.
