wopen
Task function category: Functions Operating on wdb Files
This function can be used to open .wdb files. The .wdb file must already exist to be opened in
read mode. In write mode, it will be created if it does not exist, or overwritten if it already
existed. This function returns a file identifier used in the next function to identify the .wdb file.
Usage
wopen("path/wdb1.wdb", "r" | "w")
Arguments
• "path/wdb1.wdb"
Path to the .wdb file.
• "r" | "w"
Open mode. r for read or w for write (note that it is a string).
Description
wstdout Variable
The main .wdb file (if the netlist run by the main Eldo process, containing the Control Language
task, is named netlist1.cir, then the main .wdb file will be by default netlist1.wdb) must not be
opened or closed using the functions wopen and wclose (otherwise the behavior will be
completely undefined). Instead, the predefined wstdout variable has to be used as the identifier
for this .wdb file. It is especially useful if the netlist is run with the option .option
keep_eldo_cl_temp_waves=0 to completely control how waveforms are saved in this file. See
“wdb File” in “Simulation” on page 1114.
