Reduction Restrictions
• .OPTION REDUCE_MAX_IND
• .OPTION REDUCE_MAX_RES
• .OPTION REDUCE_NETWORK_TYPE
Note
For backward compatibility, the old (pre-2009.1 release) “RC_REDUCE_*” options
are still accepted for reduction. A warning message is displayed to inform you that
this syntax is deprecated, suggesting to use .REDUCE commands instead for greater
efficiency. If both syntax is found in a netlist then the newer .REDUCE syntax takes
precedence.

Reduction Restrictions
Reduction is disabled—even when a .REDUCE command has been explicitly used—when any
of the following analyses are requested:
• Monte Carlo (see the “.MC” command in the Eldo Reference Manual)
• DC Mismatch (see the “.DCMISMATCH” command in the Eldo Reference Manual)
• Worst-Case (see the “.WCASE” command in the Eldo Reference Manual)
• Sensitivity (see the “.SENSPARAM” command in the Eldo Reference Manual)
• Steady-State Mismatch (see the “.SSTMISMATCH” command in the Eldo RF User’s
Manual)
