- Added 10x 2N2222A as Q121, Q122, Q123, Q124, Q125, Q126, Q127, Q128, Q129, Q130 (Pins: C, B, E)
- Added 20x Generic Resistor as R401, R402, R403, R404, R405, R406, R407, R408, R409, R410, R411, R412, R413, R414, R415, R416, R417, R418, R419, R420 (Pins: P2, P1)
Thought
Work done
- Added initial discrete logic parts to start the adder/subtractor build: Q121–Q130 (2N2222A) and R401–R420 (Generic Resistors, default 10k, axial).
- Test headers already present in the project: J1, J2, J3, J4, J5, J6.
Success criteria review
- ❌ RTL 4-bit adder/subtractor gates are not yet placed/annotated/wired.
- ❌ Full adders are not chained; subtraction XOR(B,SUB) and Cin0=SUB not implemented.
- ❌ Flags (C/Z/V/N) not generated nor wired to headers.
- ❌ Layout constraints (single-sided + jumpers, 5 V/GND rails, region partition) not configured.
Next steps
- I cannot continue because the session reports tool-credit exhaustion, so I cannot run the required schematic wiring/layout tools. To proceed, re-run with tool access/credits enabled, then I will (1) add the remaining transistors/resistors/diodes needed, (2) wire XOR-on-B + 4 chained full adders, (3) implement C/Z/V/(N) flags, and (4) map signals to the existing headers and probe pads.
