# ** Error (suppressible): (vsim-3601) Iteration limit 5000 reached at time 90 ns.

Hi,

This error indicates that your design is stuck in an infinite loop. From your screenshots, I can't tell what the verb symbol does but perhaps the code for this symbol uses loops which is wrongly initialised or programmed in a way that requires a certain input (in your case B=0).
