Does Ultrasim support PWLF voltage source (Voltage values derived from Time voltage file)

Hi,

I'm running a simulation in which i will have to directly import stimuli for an input signal from a file (Which has Time-Voltage pairs ),

The input netlist to Ultrasim simulator is in Hspice format,

There is a Hspice syntax for this, but i want an equivalent replacement in Ultrasim,

V1 net2 0 pwlf /home/pwl_file.in

------------------------

pwl_file.in file contains

0 0

1E-09 1

Thanks in Advance,

Let me know incase you have any questions,

Not seen that syntax before, but you should be able to do:
V1 net2 0 type=pwl file="/home/pwl_file.in"
or use spectre syntax:
simulator lang=spectre
V1 (net2 0) vsource type=pwl file="/home/pwl_file.in"
Regards,
Andrew.
