Hi,
I am super excited about some of the features that QSPICE promises. In particular the embedded C subckts. Having said this I am trying to understand how I can move over from another well loved simulation package for which I have already developed many IC behavioral models.
The first time I have spun up QSPICE I already see some functional behaviour of the waveform viewer that is not quite what I expected or what I was accustomed to. This is the ability to view simulation output in real time using āmarching waveformsā. Is this something that is already supported, if so I can not find a way to control this?
Secondly, I am curious to know if QSPICE supports the ā.MACHINEā, primitive of an arbitrary state machine. I have attempted to use one of my existing models which uses the state machine structure, but it does not seem to work. I have used arbitrary state machines extensively to build mixed signal models that include things like counters and other such ādigitalā elements. I am excited to embrace the concept of embedding āCā directly into the spice source to overcome some of the limitations of these state machine / behavioral modelling techniques, but I was hoping for a smoother path from my current models and workflow.
Furthermore debugging this process is also hampered by the fact that I can not seem to find a way to record subckt nodal voltages and currents. I also do not see these available as a manual entry from within the āadd plotā dialogue of the waveform viewer. Therefore I can only assume that the simulation does not record subckt details by default.
Any further suggestions about how, if possible, I can gain some more fine grained control of the program.
This would be very helpful.
All the best
