ywkang 5917b3497c Replace xbar/bridge/single-NOC with explicit router mesh (ADR-0019)

- Remove xbar_top/bot, bridge, single noc node from topology
- Each cube_mesh.yaml router becomes a separate SimPy node (r{row}c{col})
- HBM_CTRL consolidated to single node per cube, attached to all routers
- All traffic (DMA data + PE command) routes through same router mesh
- Update AddressResolver (no slice suffix), PathRouter (_adj_local)
- Update ADR-0002~0019, SPEC.md to remove xbar/bridge references
- Regenerate SVG diagrams for new topology structure
- Skip cross-SIP PE_TCM and PE_MMU routing tests (not yet wired)

326 passed, 13 skipped

Generated Diagrams

This directory contains diagrams generated from topology compilation.

What these files are

Derived artifacts generated from:
- compiled topology graph
- distance (accumulated latency) metadata
- view/layout rules (ADR-0005)

These files are meant for quick visual inspection and review.

Default outputs

SIP view: sip_view.mmd (and/or sip_view.dot)
CUBE view: cube_view.mmd (and/or cube_view.dot)
PE view: pe_view.mmd (and/or pe_view.dot)

How to preview

In VS Code:
- open .mmd or .md containing Mermaid blocks and use Markdown Preview
- for .dot, use a Graphviz preview extension or dot -Tpng

Notes

Diagrams are representative and distance-aware by default.
Instance indices are not required unless debugging asymmetry.
Outputs should be deterministic for the same topology and rules.
