defineVec
Note
The return value of this function is not a Tcl variable but directly a vector.
Example 2
This function demonstrates the difference between Tcl variables and PPL references. It uses
Mathematical functions with both C-like and Tcl syntaxes and returns to Eldo a reference to the
PPL object “wv_final” to plot it.
proc WAVE_REFERENCE { wv_in } {
# Define a PPL object named wv_out
defineVec wv_out "2*abs($wv_in)"
# Store a PPL refence inside a Tcl variable wv_out
set wv_out [exp $wv_in]
# Define a PPL object named wv_final using both PPL object
# wv_out and the value of Tcl variable wv_out
defineVec wv_final "wv_out + $wv_out"
# Return the final object to Eldo
return wv_final
}
A call to this function from the Eldo command:
.call_tcl tran when=END_OF_RUN PLOT=YES LABEL=Refv1 WAVE_REFERENCE(v(1))
produces a waveform named Refv1 in the .wdb output file; this waveform being the return of
the Tcl function.
Example 3
The following examples show the name of the Tcl function inside a .CALL_TCL command is
case sensitive. It must exactly match the name in the .tcl file.
