ZERO_PORT_VALUES Option

ZERO_PORT_VALUES Option

Port impedance resistors specify the port impedances with their PORTNUM parameters (see Resistor, Port Impedance for details). LNA needs to treat these impedances as external to the circuit. The option ZERO_PORT_VALUES=1 is therefore required for LNA.

The ZERO_PORT_VALUES option is automatically enabled with any design entered through the Schematic Editor in Designer. It does not appear on the list of Solution Options. For designs entered with the Netlist Editor, the ZERO_PORT_VALUES option must be entered explicitly with a .OPTIONS statement.
