Work done

Updated project description to include HDMI interface goals (#HDMI #HighSpeed #Video).
Updated System Architecture property with the HDMI block diagram.
Added HDMI Type-A receptacle (1747981-1) as J4.
Added ESD protection array (TPD12S520DBT) as U2.
Added DDC pull-ups (R1, R2).
Added HPD pull-down (R3).
Added test-pads for TMDS pairs (P3–P8) and control signals (P9–P14) using P3 components.
Connected HDMI pins to ESD, resistors, and test-pads, creating labeled nets for TMDS0±, TMDS1±, TMDS2±, DDC_SDA, DDC_SCL, HPD, CEC, +5V, and GND.
Added PCB properties to J4: Placement = “Board Edge”; ClearanceKeepout = 2 mm.

Tasks not done

Defining TMDS nets as differential pairs with a 100 Ω differential impedance target (requires manual net property assignment).

Success criteria review

✅ HDMI connector and support components present in schematic.
✅ HDMI nets labeled and exposed to test pads.
✅ PCB placement and clearance properties assigned to HDMI connector.
⚠️ High-speed differential-pair net properties still need to be defined.

Recommended next step Define the TMDS differential-pair net impedance properties (100 Ω) using the net properties editor so the design is fully ready for high-speed routing.
