Title: difference Hspice and Pspice
Post by 020170 on Apr 21^st, 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??
