In DataVector.h I commented out row 47:
DataVector(const DataVector& vector);

and in Component.h I commented out row 110:
Component( const Component& c );

and in Schematic.h I commented out row 95:
Schematic( cons Schematic& );

in order to be able to compile ViPEC.

Environment:
cygwin
gcc 3.4.4
qt3

Is the development active?

Is the development active?

I see vipec uses some qt2 classes, or at least some compat
headers. In debian also needs qt non threaded. I can help to port
the code to be full qt3-mt. is it worth to spend time in this?

tmake is not standard, but no mention of it was is made
in the INSTALL directions.

Does not compile under QT3

Anonymous — Wed, 16 Apr 2003 20:50:40 -0000

The Installation file claims ViPEC works with QT 2.20 or higher,
however I get the following error during compilation:

incorrect s-para simulation when Zo Not=50

Anonymous — Tue, 15 Apr 2003 03:57:19 -0000

I found that there are some errors in the simulated s-
parameters when Zo Not= 50. E.g., port 1 is 50, port 2
is 100, and they are connected with a quarter-wave tx
line with Zo=70.7 ohm. The simulated S21 in this case
at the center frequency should be 0 dB (no loss). But
the program gives the db(s21) as -3 dB.

Printing problem

Anonymous — Tue, 11 Feb 2003 01:31:14 -0000

I am having trouble printing the resulting graphs via
the 'print to file'
option. The results appear to be scaled incorrectly (it
is basically
scaled such that what appears on the screen is simply
scaled to fit
the page).

floating point exception in coupled line example.

Dan McMahill — Thu, 06 Feb 2003 02:05:12 -0000

when trying the coupled line filter example on my alpha
I get a floating point exception. This is sometimes
caused by using uninitialized floating point values,
perhaps the first time through a loop. The complete
debugger output is attached:

Program received signal SIGFPE, Arithmetic exception.

abnormal termination for simple 4-port

Tadashi ARAI — Tue, 17 Dec 2002 15:01:14 -0000

place a differential tline with 4 ports connected to each
end.
simulations of s11,s21,s31,s41 for 0.01-10GHz will end
up with abnormal termination.
diff-pair is 1000mm long of ze=50/zo=100ohms.
ver.3.1.3 running on windows2000pro.
