Example 20—DC Mismatch Comparison with
Monte Carlo Analysis using ECL
Netlist file: dcmismatch_vs_mcsens.cir
This example shows how to use the DCMISMATCH analysis, and compares its results to an
equivalent Monte Carlo analysis. It uses some ECL code to present the results in a compact
format (this is written to the standard output).
Please refer to the Eldo Control Language chapter and the ../examples/ecl directory for more
ECL examples.
Summary of Eldo commands used in this example:
• .DCMISMATCH—DC mismatch analysis.
• .MC—Monte Carlo analysis.
• .EXTRACT—Extract characteristics from the simulator results.
• Eldo Control Language.
Netlist Explanation
The netlist is similar to the previous example, except that the Eldo Control Language is used to
run the simulations and extract the results in a compact format.
.define_testbench dcm()
.DCMISMATCH nsigma=1
.extract dc label= dcm_offset dcm(offset)
.extract dc label= dcm_power dcm(power)
.end_define_testbench
The above lines define the testbench to be used for the DCMISMATCH analysis including the
information to be extracted.
