Cadence question about VPWLF

[jingshearer]

I want to use VPWLF source to add random noise-like signal as input of my circuit.
The file format for the signal is TXT(with time and voltage columns), can it be directly put into the "PWL file name" property of the source?
I cannot run simulation in spectre and the error is: ERROR(CMI-2011):Unable to open waveform file: "randomn"(this is the txt file) No such file or directory
Should I convert the file format or save it to a particular path?
Thx!!

Try to use the full path to the file, or copy it inside the same directory of your netlist.
