hi all,
I am simulating a bootstrap switch using conservative option in spectre. However I an getting convergance difficulties. When I go to moderate option, the simulation works fine. I have read Ken Kundert's book and i tried to fix these convergence errors but could not fix these. Has anyone done the bootstrap switch design and simulated using conservative option or i should not waste time on this as some nodes goes beyond the VDD during switching transients.
Any idea wil be highly appreciated.
