Specifying Simulation Output<br />

Extract Outputs<br />

If using the .cou format, these .EXTRACT waveforms are created in a separate file with the .ext<br />

extension. The command line switch -couext (<strong>eldo</strong> -couext -i ) can be used to<br />

merge the extract waveforms into the .cou file, when possible. In this case, a single .cou file will<br />

contain the raw waveforms and also the extraction waveforms.<br />

See “Output Quantities for Plotting and Printing” in the Eldo Reference Manual.<br />

Extracting Information<br />

Extract Outputs<br />

Extraction results are displayed in the standard output, and written to the ASCII output log file<br />

(.chi). To write results to a separate file two methods are available:<br />

• Specify option AEX.<br />

All extraction data is written to the file circuit_name.aex. Useful for sweep analysis.<br />

• Specify FILE=filename parameter of the .EXTRACT command.<br />

Results of the extract extraction are written to the file filename.<br />

You can view extraction results with the AMS Results Browser.<br />

Extract Functions<br />

There are two types of extraction language: transient and general purpose.<br />

• Transient Extraction Language:<br />

Used in transient analysis, these functions are faster to execute, and consumes less<br />

memory because they perform measurements instantaneously at each time step. They do<br />

not require the signals they use to be stored in memory. The disadvantage is that their<br />

parameters can not use results from other measurements because they can not go back in<br />

time (for example if VH or TCROSS is known at the end).<br />

Transient extraction language is based on the following functions (links open the Eldo<br />
