Assigning Parameter Values
Use the .PARAM command to assign values to parameter variables used in model and device
instantiation statements.
The following types of parameter statements are supported:
• Simple description
• Algebraic description
• Character string assignment
• User-defined function
• Monte Carlo analysis
Parameter Scoping Rules
Option PARHIER controls the priorities for parameters. When PARHIER is GLOBAL or
LOCAL, then the parameter priorities adopted in subcircuit instances (X statements) are
performed as if the operations were executed inside the subcircuit. The following rules apply:
When PARHIER=GLOBAL, the priority is the following:
1. .PARAM statement at a higher level
2. Subcircuit instantiation (X instance)
3. .SUBCKT definition
When PARHIER=LOCAL, the priority is:
