DEBUGGING SPICE
|
||
|
|
|
||
|
|
To avoid a segmentation fault in the initial run, use the following
|
||
|
|
command in gdb:
|
||
|
|
|
||
|
|
setenv SPICE_NO_DATASEG_CHECK "1"
|
||
|
|
|
||
|
|
Or, the comparable command in your shell before running gdb. This
|
||
|
|
disable accurate tracking of how much memory is used.

||

USING A GARBAGE COLLECTOR
|
||
|
|
|
||
|
|
Get the Boehm-Weiser conservative garbage collector at the following
|
||
|
|
address:
|
||
|
|
|
||
|
|
http://www.hpl.hp.com/personal/Hans_Boehm/gc/
|
||
|
|
|
||
|
|
Compile it with 'make liblinuxgc.so' and install libgc.so and gc.h
|
||
|
|
where the compiler can find them (i.e., /usr/local/lib and
|
||
|
|
/usr/local/include). Run configure and compile.

CREATING PATCHES
|
||
|
|
|
||
|
|
If you don't have access to anonymous CVS:
|
||
|
|
|
||
|
|
# extract the differences
|
||
|
|
$ diff -ruN ng-spice-rework-x ng-spice > my.patch
|
||
|
|
|
||
|
|
where ng-spice-rework-x is the snapshot you used to base your changes
|
||
|
|
on.
|
||
|
|
|
||
|
|
If you do have access to anonymous CVS:
|
||
|
|
|
||
|
|
$ cvs diff -u > my.patch
|
||
|
|
|
||
|
|
Note: this only works if you haven't added any files. Otherwise, the
|
||
|
|
first method is better.
|
||
|
|
|
||
|
|
Now, send your patch to ng-spice mailing list.

INCORPORATING PATCHES
|
||
|
|
|
||
|
|
# apply the patch
|
||
|
|
$ patch -p1 < my.patch
|

|
|
|

INCOMPATIBILITIES BETWEEN SPICE3 AND SPICE2
|
||
|
|
|
||
|
|
The output format of spice3 is slightly different for .print and .plot
|
||
|
|
lines. Most notably, different traces on plots are not scaled
|
||
|
|
independently. This is most noticeable on phase/magnitude plots from
|
||
|
|
an AC analysis (also, phase is displayed in radians). Finally,
|
||
|
|
frequency for ".PRINT AC" lines is displayed as a complex quantity
|
||
|
|
with an all-zero imaginary component.
|
||
|
|
|
||
|
|
For input, "POLY( )" sources are not supported (the non-linear
|
||
|
|
dependent source provides a more general replacement). Also, the
|
||
|
|
".ALTER" line is not supported. The Spice3 parser may be slightly
|
||
|
|
different on subtle points of reading input (lines need not start at
|
||
|
|
column 1 for instance).
