.EXTRACT Alternative
• (Used in the example.) Specify explicitly the waveforms you want in the main wdb file
(by using the “@out” argument). Do this by giving a name to waveforms (res_wave
above) and then acquire them for each simulation.
As a result, inside the main wdb file, there will be 200 waveforms.
Parallel Version
The step loop in the previous example is sequential: simulations are performed one after the
other. It is possible to run these simulations in parallel when using the parallel version of the
step loop by replacing the keywords “step” and “endstep” with “para_step” and
“end_para_step” accordingly. The parallel loops are also more restrictive than the sequential
loops (ECL will output errors to make sure the parallel code does not cause any concurrency
issues). It is advised to only run simulations in parallel and store their results inside arrays, and
to perform any post-processing computation outside the parallel loop, in a sequential loop.
The full example is located in $MGC_AMS_HOME/examples/ecl/25-step_alternative/
step_alternative_para.cir.

Statements” on page 835, and “Defining and Running Simulations” on page 841 for more
information on the concepts used in the example.

.EXTRACT Alternative
Netlist directory: 26-extract_alternative
The following example shows how the ECL can be used as an alternative to the regular
.EXTRACT commands in Eldo to print results in a custom format.
This example uses the same original netlist as used in the .STEP Alternative. Add a .EXTRACT
command to the previous netlist (inside the testbench) as follows:
* name needed for ECL
.extract tran label=res_extract xthres(v(2), 1.5)
The default display without any additional ECL custom formatting is:
