Toolchain Demos

Reference pages exercising every diagram / plot pipeline wired into the pccx Sphinx build. They exist so any regression in the toolchain surfaces as a visible break on a dedicated page rather than inside a real architecture chapter.

• Mermaid — NPU block diagram
• WaveDrom — AXI4 read transaction
• SVG — themed 4×4 PE array
• scienceplots — bandwidth vs batch size
• Plot gallery
