And I got this kind of result. There's "x" in some number like -232.833x. Could any body tell me what it means? poles (rad/sec) poles ( hertz) real imag real imag -232.667k 0. -37.0301k 0. -195.038x 0. -31.0412x 0. -1.46294g 182.958x -232.833x 29.1187x -1.46294g -182.958x -232.833x -29.1187x -3.62305g 0. -576.627x 0. -12.0109g 0. -1.91159g 0. zeros (rad/sec) zeros ( hertz) real imag real imag -192.945x 0. -30.7082x 0. -1.40462g 0. -223.553x 0. -6.12385g 0. -974.641x 0. -11.9310g 0. -1.89888g 0. 21.9447g 0. 3.49260g 0. 75.9462g 0. 12.0872g 0.

You could verify this with the .option INGOLD=2 $ View attachment hspice_simulation+analysis_user_guide_Sep_2008_p88.pdf ... which creates output format in exponential notation.
