ECC version

v0.1.0.alpha.9

Affected area

Flow/runtime

How did you get ECC?

Release PyInstaller bundle

Where are you running ECC?

Native Linux

Environment

ubuntu 22.04

Toolchain, PDK, and dependency context

ecc v0.1.0-alpha.9 (binary reports 0.1.0a6; dist-info confirms 0.1.0a9)

Steps to reproduce

When fp_default_config.json specifies macro_location_path as a relative path (e.g. "macro_locations.txt"), the run bootstrap
copies a 0-byte placeholder to runs//config/macro_locations.txt instead of resolving the path against the project root and
copying the actual file. The MacroPlacer then reads the empty file, places nothing, and completes instantly. Macros end up
collapsed at the die origin, overlapping each other.

Steps to reproduce:

1. ecc init a project, create macro_locations.txt with valid coordinates in the project root
2. In fp_default_config.json, leave "macro_location_path": "macro_locations.txt" (relative)
3. Run ecc run --project .

Expected behavior

Expected: ECC resolves macro_locations.txt relative to the project directory and copies the actual file (145 bytes, 2 macro
entries) into the run config.

Actual behavior

Actual: ECC creates a 0-byte empty file:

$ wc -c macro_locations.txt # project root
145 macro_locations.txt

$ wc -c runs/u07_d08/config/macro_locations.txt # run config
0 macro_locations.txt

Logs or command output

Floorplan log:
MacroPlacer.cpp:56 place] Starting...
MacroPlacer.cpp:65 place] Completed (elapsed = 00:00:00)

Result: macros stacked at lower-left corner, overlapping.

Workaround: Use an absolute path in fp_default_config.json:
"macro_location_path": "/absolute/path/to/project/macro_locations.txt"

Additional context

内部已经更新，到ecc上还需要一段时间。

ifp的单元面积是算上了macro，此问题是由于另一个bug引起。
