[Gnucap-devel] New gnucap development snapshot 2007-03-29

[al davis]

There is a new development snapshot of gnucap available.

There's a package at:
http://www.gnucap.org/devel/gnucap-2007-03-29.tar.gz
or
http://geda.seul.org/dist/gnucap-2007-03-29.tar.gz

Models have also been updated:

http://www.gnucap.org/devel/gnucap-2007-03-29-ngspice17-models.tar.gz
http://www.gnucap.org/devel/gnucap-2007-03-29-spice3f5-models.tar.gz
or

http://geda.seul.org/dist/gnucap-2007-03-29-spice3f5-models.tar.gz

And .....  There's a new one:
http://www.gnucap.org/devel/gnucap-2007-03-29-tools.tar.gz
or
http://geda.seul.org/dist/gnucap-2007-03-29-tools.tar.gz

The new one contains tools plugins.  For now, there are two 
plugins to adjust calculation precision.  One selects full 80 
bit precision on systems that by default round to 64 bit.  The 
other selects 64 bit IEEE compliant math on systems that 
default to 80 bit.  These only work on Intel and AMD 32 bit 
CPU's.  They have no effect on AMD 64 bit CPU's.

This snapshot provides (over the old one) ...
1. Correction of internal node mapping bug.  When using spice 
plugins, in some cases internal nodes were not mapped correctly 
giving incorrect results.  This has been fixed.

2. The initialization order - link order dependency has been 
fixed.

3. The "s_" files, the code for simulation itself can now be 
compiled separately and used as plugins.  They are still 
compiled in by default, but you can change that

4. A problem with incremental matrix update, that sometimes led 
to incorrect results after recovery from a convergence failure 
has been fixed.  A technical explanation will be posted on the 
developer list.

5. There has been a change to the compilation procedure for the 
plugins.



As usual, I am asking for feedback, particularly on non-Linux 
and non-GNU systems.

This one is still very much a development snapshot.  The 
arrangement of files and compilation procedure WILL change 
before the next stable release.  Most likely it will change in 
the next development snapshot.
