E2E Test Plan

Phase 1: CLI Smoke Test (Manual)

# Test 1: Help command
tri fpga build --help
# Expected: Usage information displayed

# Test 2: Missing input
tri fpga build
# Expected: Error message with usage hint

# Test 3: Unsupported file type
echo "test" > /tmp/test.txt
tri fpga build /tmp/test.txt
# Expected: Error: Unsupported input type

Phase 2: Synthesis Tests (requires tri binary)

# Test 4: Simple design synthesis
tri fpga build fpga/openxc7-synth/blink.v

# Test 5: Verbose output
tri fpga build fpga/openxc7-synth/counter.v --verbose

# Test 6: Custom output path
tri fpga build fpga/openxc7-synth/blink.v --out /tmp/blink_test.bit

# Test 7: With verification (if hardware available)
tri fpga build fpga/openxc7-synth/blink.v --verify

Phase 3: Hardware Verification (Optional)

# Flash bitstream to FPGA
# Requires: Xilinx Platform Cable USB II

# Test 8: LED blink verification
# Flash blink.bit and verify D6 LED blinks

# Test 9: UART functionality
# Flash uart_top.bit and verify UART output

Current Status

Pre-existing Compilation Issues

Note: The tri binary has pre-existing compilation errors in:

• src/tri/tri_job.zig:173 — undeclared _artifact_paths
• src/tri/job_system.zig:270 — type mismatch in getLogs()

These errors prevent E2E testing of tri fpga build at this time.

Workaround

Direct synth.sh usage still works:

cd fpga/openxc7-synth
./synth.sh blink.v

TODO 7 Scope Limitation

Due to pre-existing tri compilation errors:

• SA-6 E2E tests are PLANNED but not executed
• tri fpga build command is IMPLEMENTED but not runtime-tested
• Synthesis.sh wrapper is UPDATED with deprecation notice

---

Expected Results (When tri binary is fixed)

Test	Command	Expected Output	Artifact
T1	tri fpga build --help	Usage banner	—
T2	tri fpga build blink.v	✓ FPGA build complete	build/blink.bit
T3	tri fpga build counter.v --verbose	Detailed log	build/counter.bit
T4	tri fpga build uart.v --out /tmp/test.bit	Custom path output	/tmp/test.bit
T5	tri fpga build bad.txt	Error: unsupported type	—

---

Baseline Performance (synth.sh)

Design	Synthesis Time	Bitstream Size	Status
blink.v	~30s	~15KB	✅ Working
counter.v	~35s	~18KB	✅ Working
uart_top.v	~45s	~25KB	✅ Working

Note: These times include Docker container startup.

---

Hardware Verification Status

Design	Hardware Test	Result	Evidence
d6_blink	LED D6 blinking	⚠️ OLOGIC bug	LED stuck ON
uart_top	UART TX/RX	⚠️ Not tested	Pending
blink	LED behavior	✅ Works (GA)	GA evidence exists

---

Success Criteria

TODO 7 is considered complete for SA-6 if:

• Test plan documented
• Reference designs identified
• CLI smoke tests pass (blocked by tri compilation errors)
• Synthesis tests pass (blocked by tri compilation errors)
• Documentation updated with correct usage

Blocker: Pre-existing compilation errors in tri_job.zig and job_system.zig

---

Next Steps

For TODO 7 completion:

1. Accept E2E tests as PLANNED due to pre-existing issues
2. Document the workaround (use synth.sh directly)
3. Note in verdict that E2E validation will be done when tri is fixed

For TODO 8+ (post-GA):

1. Fix tri compilation errors
2. Run full E2E test suite
3. Add hardware verification automation
4. Benchmark synth.sh vs tri fpga build performance
