Nexxim Simulator > Voltage-Controlled Switch, SPDT
Netlist FormatAn instance of avoltage-controlled single-pole, double throw switch has the following netlist syntax: Exxx ( n1 n2 n3 n4 n5 ) VSPDT [ROFF=val] [RON=val] [IOFF=val] [ION=val] [AREA=val] n1 is the input node, n2 is the “OFF” output node, n3 is the “ON” output node, n4 and n5 are the control nodes. The parentheses around the list of node names are required. The entry VSPDT identifies the element as a voltage-controlled SPDT switch.
Netlist Examplev1 c1 0 SIN(0 10 1e6) // Control voltage R1 c1 0 1 Vn1 n1 0 10 Rn2 n2 0 10 Rn3 n3 0 10
E1 (n1 n2 n3 c1 0) vspdt von=1 Notes1. In normal operation, VON is greater than VOFF. Output node n2 is selected whencontrol voltage VC is less than or equal to VOFF, and output node n3 is selected when VC is greater than or equal to VON. 2. In inverted operation, VOFF is greater than VON. Output node n2 is selected when VC is greater than or equal to VOFF, and output node n3 is selected when VC is less than or equal to VON. VSPDT Model EquationsG1 is the conductance betrween node 1 and node 2. G2 is the conductance between node 1 and node 3. If ((VON >=VOFF && VC >= VON) || (VON < VOFF && VC <= VON)):
Else if ((VON >= VOFF && VC <= VOFF) || (VON < VOFF && VC >= VOFF)):
Else:
