Setting Up Different Port References for a SPICE Network
Define SPICE files with an absolute or relative port reference for a SPICE
network.
Example of a SPICE file with an absolute port reference
A SPICE example of pi-network using an absolute port reference (each port is
referenced to the SPICE global ground n0). The total number of output nodes is equal
to the amount of network terminals when creating a general network.Figure 1. Example of a circuit using an absolute reference (node 0).
Example of a SPICE file using an relative port reference
A SPICE example of a pi-network using a relative port reference, exposing the
negative and positive pins of each terminal in the network. The total number of
output nodes is double the amount of network terminals.Figure 2. Example of a circuit using an relative reference.
