Help us create test benches for the tools we maintain. See |
| 50 |
<uri link="../todo.xml#doc_chap1">the 'Test benches' entry in our TODO list</uri>. |

Instructions on how to test our packages and verify they work properly should get |
| 54 |
listed below. Developers, please remember that a non-specialist must be able to |
| 55 |
execute your test bench. List packages alphabetically, and store any required |
| 56 |
additional material in a bz2 tarball in the same directory as this guide. |

An example is available in the source tarball. You can install its files by emerging |
| 69 |
GTKWave with USE=examples, which is what we are going to assume in the following |
| 70 |
instructions. You should replace ${PF} with the corresponding number of the version |
| 71 |
(with the revision) you want to test. |

In the SST window (left side, towards the top) navigate down the hierarchy of signals, |
| 89 |
then drag and drop a few signals from the 'Signals' window below the SST window, to the |
| 90 |
other 'Signals' window just right of SST. Play with signals a bit, zoom in, zoom out, etc... |
