Full module reference

sycan.circuit	Netlist container.
sycan.mna	MNA infrastructure: component base, stamping context, and solvers.
sycan.check	Schematic / netlist electrical-rule checks.
sycan.headroom	Headroom analysis — symbolic input range that keeps every MOSFET saturated.
sycan.network_params	Network-parameter conversions for two-port (and n-port where it applies) representations: Z, Y, S, ABCD, T.
