Reduction Commands
A number of reduction commands are available in Eldo:
• .REDUCE
Actives a combination of TICER, RONLY, and/or CC reduction methods expected to be
well suited for the circuit being reduced.
See “.REDUCE” in the Eldo Reference Manual.
• .REDUCE CC
Controls reduction of coupled capacitance between RLC or RC nets based on total
capacitance.
See “.REDUCE CC” in the Eldo Reference Manual.
• .REDUCE RONLY
Reduces resistive-only networks by eliminating all internal nodes.
See “.REDUCE RONLY” in the Eldo Reference Manual.
• .REDUCE TICER
Specifies to perform TICER reduction in a way that has little impact on circuit
characteristics, such as delay up to a specified frequency.
See “.REDUCE TICER” in the Eldo Reference Manual.

A number of options are provided with the aim of helping the reduction process to achieve
greater efficiency or controlling the topological impact of reduction on the circuit.
The following topics in the Eldo Reference Manual detail each option:
• .OPTION REDUCE_KEEP_INST
• .OPTION REDUCE_KEEP_NODE
• .OPTION REDUCE_KEEP_OUTPUTS
• .OPTION REDUCE_MAX_CAP
