4 These are the original tests used by gnetlist which compare the
5 netlister output for a set of test schematics with known good output
6 files. To run the tests, type:
10 Since xorn-netlist produces slightly different output than the old
11 gnetlist binary, the reference output files have been modified to
12 accomodate these differences.
14 - The original order in which the pins on a net used to be listed in
15 gnetlist is hard to predict and depends on the internal connectivity
16 checking algorithm. Since it's *almost* the order of the pins in
17 the file, they are now sorted in that order.
19 - The VAMS backend included all attributes on the first component of a
20 package in the output except "refdes", "source", and "architecture".
21 For slotted packages, this means a semi-arbitrary value for "slot"
22 was used. The new attribute code considers all components of a
23 package and raises an error if there are inconsistent values.
24 Therefore, the "slot" attribute is now excluded, too.
26 - gnetlist:vams-get-package-attributes returned the names of all
27 attributes attached to a package's first component, including those
28 which have been set to "unknown". This has been fixed; now only
29 attributes whose value is not "unknown" are listed in the output.
31 - If an artificial pin was present in multiple components of a
32 package, get-pins and get-pins-nets returned the pin once for each
33 component, resulting in duplicate pins in the output. This has been
34 fixed; each pin in now listed only once.
36 - The renamed-nets section in the test backend has been removed as it
37 isn't meaningful any longer.
39 - With the new subsheet link-up code, the order of the pins on an
40 inter-schematic net connected to multiple ports now depends
41 primarily on the order of the pins of the subsheet symbol instead of
42 the order of the pins inside the subsheet.
44 - Some of the errors covered in the DRC2 tests are now detected by the
45 netlister and cause it to abort with an error, so netlist errors are
46 ignored for this backend.
48 The tests do NOT cover most of the more advanced features of the
49 backends; they are basically just a bunch of standard schematics run
50 through each backend, whether meaningful or not.
52 Please note that the tests only make sure there are no accidental new
53 defects. In particular, it has not been checked whether the original
54 output files were correct in the first place.
