The way the construction of the SPICE measurement is implemented in piel is also microservice-esque. Larger circuits are constructed out of smaller building blocks. This means that simulation configurations and so on are constructed upon a provided initial circuit, and the SPICE directives are appended accordingly.

As mentioned previously, piel creates circuits based on fundamental SPICE because this opens the possibility to large scale integration of these circuit measurement on different SPICE solvers, including proprietary ones as long as the SPICE circuit can be written to particular directories. However, due to the ease of circuit integration, and translation that hdl21 provides, it’s API can also be used to implement parametrised functionality, although it is easy to export the circuit as a raw SPICE directive after composition.

This composition tends to be implemented in a SubCircuit hierarchical implementation, as this allows for more modularisation of the netlisted devices.

Let’s assume that we can get an extracted SPICE netlist of our circuit, that includes all nodes, and component circuit definitions. This could then be simulated accordingly for the whole circuit between inputs and outputs. This would have to be constructed out of component measurement and a provided netlist in a similar fashion to SAX.
