add documentation for bit extender component #431
Conversation
WalkthroughA new section was appended to the Chapter 4 "Misc" documentation page, introducing and describing the Bit Extender circuit element. The addition covers its configurable properties, operational behavior, ports, extension strategies, and provides an illustrative example. No changes were made to existing documentation or code.

19-19: TOC entry numbering will auto-renumber – explicit “11.” is redundant
Markdown ordered lists automatically render consecutive numbers; keeping a literal11.after10.is fine, but if items are later re-ordered it will silently update. Consider replacing the hard-coded11.with1.(or leaving it blank) to avoid future maintenance noise.
549-560: Edge-case behaviour needs one-sentence clarification
You specify truncation “from the MSB side” when the input is wider than the output. Add a short note that this preserves the least-significant bits (LSBs) so readers know which side is retained.

544-546: Verify image pathname and figure numbering
The new figure path/img/img_chapter4/4.25.pngand caption “Figure 4.25” continue the existing sequence, but ensure the actual asset is committed and the numbering doesn’t clash with later figures added by other PRs.

🛠️ Refactor suggestion
Ports vs. properties are conflated – revise column names
Bit Width In and Bit Width Out are configurable properties, not electrical ports. Presenting them in a “Ports” table is misleading. Typically the Bit Extender exposes one input port (e.g. In) and one output port (e.g. Out), plus an optional input port when Extension Type = Input.
Suggested minimal fix: rename the table to “Configurable Properties & Optional Port” and separate the true port(s):
-| **Name** | **Description** |
-|-------------------|-----------------|
-| `Bit Width In` | Input value to be extended |
-| `Bit Width Out` | Output after extension |
-| `input` (optional) | Used only when `Extension Type = Input`; specifies the extension bit |
+| **Name** | **Type** | **Description** |
+|----------|---------|-----------------|
+| `In` | Port | Input value to be extended |
+| `Out` | Port | Extended output |
+| `input` *(optional)* | Port | Filler bit when `Extension Type = Input` |
+| `Bit Width In` | Property | Width of `In` |
+| `Bit Width Out` | Property | Width of `Out` |
+| `Extension Type`| Property | Zero / One / Sign / Input |
+| `Direction` | Property | Orientation on canvas |📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In docs/chapter4/8misc.md around lines 530 to 541, the table incorrectly mixes
configurable properties with electrical ports, causing confusion. Rename the
table header to "Configurable Properties & Optional Port" to clarify this
distinction, and separate the actual ports like `In` and `Out` into a different
section or table to clearly differentiate them from properties such as `Bit
Width In` and `Bit Width Out`.

Remove or replace the placeholder embed link
The embedded circuit section still contains a commented TODO link. Either supply the correct CircuitVerse embed URL or delete the placeholder to avoid dead-content in the published docs.

In docs/chapter4/8misc.md at line 574, there is a commented placeholder embed
link with a TODO that should not remain in the published documentation. Either
replace this placeholder with the correct CircuitVerse embed URL for the Pull
Resistor Simulation or remove the entire commented line to prevent dead or
incomplete content in the docs.
