Walkthrough

Two discrete changes: addition of twelve pad-ring configuration control ports to the hardware top-level module (all wired to constant zero), and updates to three Python dependency versions in the requirements file (siliconcompiler, lambdapdk, and lambdalib).

Changes

Cohort / File(s)	Summary
Hardware Pad-Ring Configuration hw/asic_top.v	Added 12 new pad-ring control ports (no_schmitt, no_fast, no_ds; ea_schmitt, ea_fast, ea_ds; so_schmitt, so_fast, so_ds; we_schmitt, we_fast, we_ds) to the padring instantiation, each wired to constant 'b0
Python Dependency Updates python-requirements.txt	Updated package versions: siliconcompiler (0.25.x → 0.36.x), lambdapdk (0.2.x → 0.2.8), lambdalib (0.8.x → 0.9.0)

🐰 Ports and wires, steadfast and true,
Twelve new companions in constant 'b0 hue,
Dependencies shimmer with versions grown bright,
The padring rings out—all is configured right! ✨

siliconcompiler 0.36.0 PyPI release

💡 Result:

SiliconCompiler 0.36.0 was released on PyPI on January 6, 2026 (install: pip install siliconcompiler==0.36.0). It provides an sdist (siliconcompiler-0.36.0.tar.gz) and a universal wheel (siliconcompiler-0.36.0-py3-none-any.whl), and requires Python >= 3.9. [1]

Release notes highlight a major schema change to better handle timing constraints by splitting mode-specific info from scenarios, plus several minor execution/flowgraph/tooling fixes. [2]

Fix lambdapdk version constraint—0.2.8 does not exist on PyPI.

lambdapdk >= 0.2.8 cannot be satisfied; the latest published version is 0.2.7 (released Jan 13, 2026). Update the requirement to lambdapdk >= 0.2.7. The other two versions are available: siliconcompiler 0.36.0 (Jan 6, 2026) and lambdalib 0.9.0 (Jan 27, 2026).
