Creating a component that allows setting a changing value on a bus in a single transient simulation

Hi everyone,

The cell "bussetp" introduced in the link below works pretty well, if the bus value is static in transient simulation.

In some transient simulation, we would like to define the "bus value" as different value at time points in a single transient simulation.

e.g. t1=10ns, bus_value=3; t2= 30ns, bus_value=5, t3=60ns, bus_value=2,...

Is it possible to edit the script to support above data set?

I see there is "pwl" option in "vcvs". Is it similar to "pwl" in "vsource"?

Can we define parameter "busvalue" as a vector, and then put the vector as value of "pwl"?

Thanks and regards,

Yutao
