Integrated heavy copper planes
0:32
Started: Integrate heavy copper planes, local decoupling, fusing, and TVS protection appropriate for high-current application..
Added internal data bus connectors
0:33
Started: Add connectors for internal data buses (polynomial, ciphertext, proof) and make net connections between these connector pins and their respective bus nets.
Added multi-pin status/GPIO header
0:24
Started: Add a multi-pin status/GPIO header and make net connections from each component’s status and GPIO pins to the corresponding header pins.
Implemented thermal management zones
0:30
Started: Implement thermal management zones within the OAM outline and place cooling-related components.
Applied placement rules
0:29
Started: Apply placement rules for EMI and thermal performance.
Ran ERC and DRC reviews
0:23
Started: Run ERC and DRC reviews to verify electrical and mechanical constraints.
