None.
- BUGFIX: Respect the user config when saving to file.
- BUGFIX: Respect CLI-specified transient DFs.
- BUGFIX: use the warning interface.
- BUGFIX: always set the simulation options before running tests.
- BUGFIX: fix detection of wd
- BUGFIX: .include now recovers the path relative to the netlist
- BUGFIX: fix printing of .DC statements.
- BUGFIX: fix comparison of int and NoneType (new Python behaviour)
Version 0.11 represent the culmination of four months of efforts.
- Add Pole-Zero (.pz) analysis.
- Add sparse matrix support and LU factorization with SuperLU.
- AC solutions data is returned as complex floats.
- The brute-force PSS algo is now known as 'brute-force'.
Ahkab also got considerably faster in DC/OP/TRAN/PSS analyses.
A PY3 version passing the whole test suite is available in the repository.
None.
- BUGFIX: AC sweeps consistently default to LOG.
- BUGFIX: Convert print_netlist_elem_line to get_...
- BUGFIX: parse_analysis() is not a generator anymore`.
- BUGFIX: Remove print_circuit(), use print(circuit).
- BUGFIX: EKV devices now match the usual constructor.
- BUGFIX: do not attempt to print conv. details if sing. MNA
- BUGFIX: Use ndarrays (almost) everywhere, drop mats.
- BUGFIX: Don't crash if a plot label is not found.
- BUGFIX: CMIN-related crash.
- BUGFIX: Remove hack for now closed bug in sympy.
- BUGFIX: Reset sim options before skipping a test.
- BUGFIX: allow printing of PSS results.
- BUGFIX: inductor coupling and time function parsing.
- BUGFIX: fix checking of symbolic results.
- BUGFIX: InductorCoupling: init syntax and
add print_netlist_elem_line()
. - BUGFIX: fix regression in TF calculation (wrong sympy assumptions).
- BUGFIX: function parsing
- BUGFIX: fix 'autonomous' dest value.
- BUGFIX:
modify_x0_for_ic()
should NOT modify op results. - BUGFIX: op table size
- BUGFIX: MOSQ init param order
- BUGFIX: Symbolic analysis bugfix.
- BUGFIX: Fix DC sweeps.
- BUGFIX: Fix dict access of OP results. OP info now goes to info file.
- BUGFIX: Deep copy
an_list
so that we can pop out items as we please transparently to the user. - BUGFIX: take the file.op into account. Also abs paths.
- BUGFIX: load_csv crash, add late check for headers consistency.
- BUGFIX: Fix the sine function. Notice the meaning of theta changed with this commit.
- BUGFIX: Correct assumptions in subs.
- BUGFIX: fix
element.part_id
in subckts - BUGFIX: testing, do not compare time exec results from different machines.
- Incorporate most changes from @weilawei.
- Merge pull request #18 from endolith/patch-1
- Merge branch 'patch-1' of https://github.com/mightyiam/ahkab
- Use
__version__.py
for versioning - Diode: Enable caching. Simplify interfaces.
- Allow running lists of analyses, or 1 analysis alone too.
- Add gnd as
mycirc.gnd
. - Add command line entry point to
setup.py
. - Testing: Add APITest to automate testing of the
ahkab
Python interface. - Testing: Test suite running on Travis, with coverage.
- Testing: Selective test skipping on Travis-CI
- Massive refactoring of the code base: enforce PEP8 everywhere.
- Symbolic: transfer functions are results instances too.
- Plotting: remove useless functions, keep some as internal-only.
get_headers_index(..., load_headers=[])
returns all header indices.- Testing: No reference runs with nose.
- Ticker: simplify the ticker API.
- Speed up the matrix assembly precomputing conductances
- Allow printing out to stdout also
if filename == '-' or sys.stdout
- Matplotlib auto backend selection for machines without
$DISPLAY
- Rewrite csvlib to use numpy's R&W methods
- Elements now print out their own netlist entries.
- Move
convergence_check()
to utilities. - Use relative imports and move to single versioning of files.
- Remove def. values from time functions
Thanks to @weilawei**, @endolith, @mightyiam for their contributions.
** Big thanks man, excellent job.
- Added support for voltage-controlled switches
- Improved diode model with temperature support (but no capacitances).
- Dropped psycho support.
- Re-added the quadratic law MOS transistor model.
- Updated wiki pages and examples.
- Many small fixes.
- Ahkab can now be run in a Python program.
- Dropped gnuplot support, ahkab now requires matplotlib.
