rigid loop

hi there,
what does rigid loop mean in spectre, because i encountered a rigid loop error during topology check and failed the simulation, i wonder how to get rid of this kind of error, i am happy about any comment, thanks!

rigid loop

i think it may be a loop of sources, i.e. two parallel voltage sources
