Gnucap 0.34 release notes (02/01/2004)
This is a bug fix and compatibility release.
1. Fix bug causing incorrect interpolation of backwards tables.
2. Fix tanh overflow bug.
3. Fix some parsing bugs.
4. Fix occasional "double load" bug.
5. Fix AC sweep with one point.
6. Transient start time really works.
7. Fix occasional assert fail after option short is changed.
8. Fix memory leak resulting from failure to delete unused common.
9. Fix a Z probe bug that sometimes gave wrong answers.
10. Fix a limiting bug that sometimes caused non-convergence.
11. Configure handles isnan.
12. Improvements to logic initialization. It is still not correct.
Some things that are still partially implemented:
1. BSIM models, charge effects, "alpha0" parameter. (computed then
ignored)
2. Configure still doesn't handle everything.
3. The model compiler still requires too much raw coding.
4. Named nodes. If you set the option "namednodes", it will support
named nodes, but some things don't work, so it is off by default.
5. The preliminary IBIS code is now included. For now, it is a
standalone executable, that reads an IBIS file and generates a
netlist. The netlist requires some editing to use, and is not fully
compatible anyway. It is included in hopes of recruiting help in
finishing the project.
Bugs (nothing new, but needs repeating):
1. The transmission line initial conditions are not propagated until
the transient analysis runs.
2. An occasional bogus calculation in MOSFETS occurs when a device is
reversed. This sometimes causes nonconvergence.
3. Initialization is strange when repeating an analysis without an
intermediate edit.
Hot items for a future release (no promises, but highly probable):
1. Verilog-AMS and VHDL-AMS support.
From the NEWS file:
This release is basically a 0.2.1 release with the available bug fixes
patches applied to it. This should make getting a stable release less
tedious.
rather than using LOWER_OPSYS. This is because the couple of os's
that had correct targets were the same and others that pkgsrc works on
aren't listed at all (like solaris). Fixes build problems noted on
solaris.

2003-10-06 Stefan Petersen <spe@stacken.kth.se>
* src/draw_amacro.c: Drawing of aperture macro primitive 7 was
severly broken. Revealed by Drew Moore who sent an example
along. Thanks Drew! Closes bug #818307.
2003-09-28 Stefan Petersen <spe@stacken.kth.se>
* src/gerber.c: Patch from Peter Brueckner. Some Gerbers don't
have G04 but just G4. Peters patch fixes that for G- and M-codes.
2003-09-08 Stefan Petersen <spe@stacken.kth.se>
* src/gerber.c: Patch from Simon Munton to fix a problem with polygons
sometimes not being filled properly. Closes bug #800928 (which
he promptly had submitted).
* src/gerber.c: Another patch from Simon. This time it fixes
circular polygon outlines by with a number of short segments.
Closes bug #603183, which was almost a year old. Thanks Simon!
curses.buildlink2.mk. This was wrong because we _really_ do want to
express that we want _n_curses when we include the buildlink2.mk file.
We should have a better way to say that the NetBSD curses doesn't
quite work well enough. In fact, it's far better to depend on ncurses
by default, and exceptionally note when it's okay to use NetBSD curses
for specific packages. We will look into this again in the future.
