Silicon Die Zoom

Why this exists

Every CSA-101 lecture opens by showing you the destination. The 6502 die is a small rectangle of silicon with named blocks: arithmetic over here, registers over there, the decoder that turns opcode bytes into control signals down the middle. Each week you build one of those blocks in the HDL simulator. The die zoom lights up the conceptual region you just built so the floorplan grows in your head at the same rate the chip grows on the page.

Scroll the panels on the left. The die on the right zooms and highlights as you go. The NAND-budget tracker embed in the side panel climbs the same gate count your lab adds. The destination is the last scene: every block lit, the bus pulsing, your hand-assembled 6502 program running on silicon you built.
