Nexxim Simulator > Resistor, Expression-Based (Netlist Only)
Instead of the standard resistor syntax with a specified resistance value, you can define the resistance by an expression, using the syntax given in this section.
Expression-Based Resistor Instance Netlist SyntaxRxxxx n1 n2 [modelname] [R=]'expression' [[TC1=]val] [[TC2=]val] [M=val] [DTEMP=val] [SCALE=val] [L=val] [W=val] [C=val] n1 is the positive node and n2 is the negative node of the resistor. The current is assumed to flow from n1 through the resistor to n2. If a model statement is provided for the resistor, the modelname is its name. The expression defines the resistance as a function of voltages and currents in the netlist. The expression should be enclosed in single quotation marks. The label R= is optional. The first unlabeled value after a modelname is taken to be the resistance value. The syntax above shows the labels TC1= and TC2= as optional, but this option depends on the presence or absence of the resistance value, labeled or unlabeled: When both modelname and the resistance value are present but the resistance value does not have the R= label, the next two unlabeled values are taken to be TC1, then TC2. To specify a value for TC2, either a value for TC1 must be given as well, or the label TC2= must be used. When the resistance value is present with the R= label, the labels TC1= and TC2= are required.
Expression-Based Resistor Instance Netlist ExampleR25 IN1 N23 R='V(IN1,N23)/2.0e-5' Expression-Based Resistor ModelThe model netlist syntax and parameters for the expression-based resistor are identical to those for the standard resistor (see Resistor Model).
