Title: difference Hspice and Pspice Post by 020170 on Apr 21st, 2005, 5:01pm I designed very simple RC circuit like that. vac 1 0 ac 120v r1 1 2 200 r2 2 0 400 c1 2 0 10u .ac lin 1 60 60 .print ac vm(1,2) im(r1) vp(1,2) vm(2) vdb(2) vm(1) .end when I run it in Pspice & Hspice, the results is different. but I don't know why ------------------------------------------------------------ *Hspice result freq voltage m i mag volt phase voltage m 1 r1 1 2 2 2 60.00000 48.5219 323.3326m 26.6866 71.4781 ------------------------------------------------------------ *Pspice result FREQ VM(1,2) IM(r1) VP(1,2) VM(2) 6.000E+01 6.467E+01 3.233E-01 2.976E+01 7.148E+01 -------------------------------------------------------------- why is so different in voltage magnitude ? especially VM(1,2)?? in my opinion, Hspice may be correct. how about your opinion? when I calculated the value of voltage magnitude (1,2) in my hand, I got a answer that was similar to Pspice result. Am I wrong?? |
