Right now, running `tt_fpga.py --project-dir example/<projectname>
harden` will fail if previously, `tt_fpga.py harden` was ran against a
project in the root folder. This is because the `_tt_fpga_top.v` file is
always read from `src/_tt_fpga_top.v`, even though it's generated in the
proper --project-dir location.
Similar problem affects the `configure` command, where it looks for the
bitstream in `build/<name>.bin` relative to the current dir even with
`--project-dir` set.
Commit prepends the source_dir from `--project-dir` in the appropriate
places such that it's used for both harden and configure.
Tested by observing that running the following commands in sequence now
succeeds against one of my projects:
- tt_fpga.py harden
- tt_fpga.py --project-dir examples/tt_um_vga_example_gamepad harden
- tt_fpga.py --project-dir examples/tt_um_vga_example_gamepad configure
--upload --port /dev/ttyACM0
The previous version of the boundary check was a quick heuristic where
we compared the bounding box of the design to that of the prBoundary layer.
Over time we came across some designs where this is insufficient.
The new check compares the bounding box to the correct project size
based on the .def template and verifies that there is a rectangle of
this exact size in the prBoundary layer at the top level.
The patch also abstracts parsing the .def template into a separate
function since we now use it in two different checks.
Sylvain: The techfile for GF180 is still a bit dodgy in some areas,
especially when reading from GDS and it's rejecting perfectly valid designs.
Wafer.space relies only on KLayout DRC for acceptance so we should do
too for the time being.
The flag enables a second power supply (VAPWR), not necessarily 3.3V (gf180's core is already 3v3), so "uses_3v3" no longer accurately describes its purpose.
Rename it across project_info, precheck, project and shuttle, and update the validation message accordingly.
The legacy "uses_3v3" key is still accepted when reading info.yaml, so existing project configs keep working.
Previous fix caused issue with resistors since that check must not
apply to anything in prec_res zone according to licon.9

* feat: add interactive document checker
This utility can be used to audit the documentation of the projects on the shuttle, marking them to be removed from the datasheet.
Usage:
`python3 tt/configure.py --doc-check`, inspect using `nano` controls, then answer prompt upon exiting `nano`.
The shuttle datasheet flow was updated to santise strings properly, and within the changes were some updates to the template that was used. This template is shared between the shuttle and individual projects, but the standalone version wasn't updated to be compatible. This commit rectifies that issue.
User strings were used as-is in certain parts since they were taken directly from `info.yaml`, but this could sometimes cause the datasheet build to fail since they've found a way (intentionally or not) to escape the content box that they were in.
This commit attempts to address this issue by:
- Sanitising user input using regex
- Using Typst's `str()` function instead of content boxes where possible
- Clarifying syntax in certain sections
Hopefully these changes will remove (or at least reduce) the chances of someone breaking the build.
