cadence pwlf bus

Hi,

I want to use data from MATLAB as an input vector for my Spectre simulations.
In the past, I created a seperate pwlf source for each bit of the bus.
This worked well, for small small bus widths .

Now my bus is becoming quite large (+64b).

What is the easiest way to import such data?

You could perhaps use an ideal DAC mechanism in MATLAB to transfer your bus into an analog signal, feed it to Spectre's ADE and re-convert it there with an ideal (behavorial, {A,V}HDL) ADC back into the bus format.
I don't know, however, if the accuracy is sufficient.
