.MC Statement

The .MC statement configures Monte Carlo analysis, running the simulation multiple times with random parameter variations to assess statistical behavior.

Syntax

.MC <runs> <analysis_type> <output_variable> <function> [SEED=<value>]
Parameter Description
runs Number of Monte Carlo iterations
analysis_type OP, DC, TRAN, AC, or NOISE
output_variable Signal to monitor
function Statistical analysis function
SEED=<value> Optional random seed for reproducibility

Example

Monte Carlo analysis
V1 IN 0 1
R1 IN OUT 1k
C1 OUT 0 1u
.MC 100 TRAN V(OUT) MAX SEED=42
.TRAN 1e-6 10e-3
.SAVE V(OUT)
.END

Parameter Tolerances

Monte Carlo analysis varies parameters that have defined tolerances. Tolerances are specified in model parameters or via distribution definitions (see .DISTRIBUTION).

Notes

  • The SEED parameter ensures repeatable results across runs.
  • Use .DISTRIBUTION to define custom probability density functions.
  • Use .OPTIONS DISTRIBUTION=<name> to set the default distribution.
