When simulating the phase noise of my charge pump using PSS/PNOISE, I am seeing an error message saying "Relative residual of linear system is significantly above tolerance. Results may be inaccurate." The message occurs for frequency steps between 100Hz and 500Hz, then does not appear for the higher frequency steps. Has anyone seen this error message before? Thanks.
