Resistor Device
The Spectre resistor device is translated as an ADS resistor device. For information on the resistor model, refer to R_Model (Resistor Model).
Example Spectre Command Line:
Without model referenced:
r1 (1 2) resistor r=1.2k m=2
With model referenced:
r1 (1 2) resmod l=8u w=1u
Spectre Netlist Syntax:
Without model referenced:
name n1 n2 resistor [param= value ]*
With model referenced:
name n1 n2 mname [param= value ]*
ADS Netlist Syntax:
R: rid n1 n2 R= value [param= value ]*
ADS Schematic Symbol:

Instance Parameters:

Comments:
- The value of R may be positive or negative but not zero in the netlist.
- The value of R cannot be an expression that changes during the simulation.
- If SCALE is specified, Value = Value * scale .
- If trise is provided, Temp = trise + temp ( temp is an ADS global variable).
