Hello HSPICE gurus, There is an example in the HSPICE manual on p. 4-11 of the=20 "HSPICE Simulation and Analysis User Guide" v. 2004.03 for charge conserving capacitors: ---------------------------------------------------------------- Charge-Conserving Capacitors Cxxx n1 n2 . . . Q =3D 'equation' EXAMPLE 1: C1 a b Q =3D 'sin(V(a,b)) + V(c,d)*V(a,b)' The above equation is equivalent to: C1 a b C =3D 'cos (V(a,b)) + V(c,d)' Note: Charge-conserving capacitors are a more-accurate solution. ---------------------------------------------------------------- I tried the first line with the "Q =3D ... " syntax and I get an error: **error** no definition for 0:q =20 it was called by 0:cxxx Does anyone know whether the "Q" is allowed in a capacitor equation, and if so how it should be used? Or should the manual be interpreted as "If you want to write something like the first line, you should write it as the second line"? Thanks, Arpad =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
