Reports - TDT Tessera Design Toolkit

Available Reports

TDT generates professional reports directly from your plain-text data. All reports support multiple output formats.

FMEA Report

tdt report fmea

Failure Mode and Effects Analysis with RPN scoring, severity rankings, and mitigation tracking.

RPN Calculation Risk Priority Mitigations

BOM Report

tdt report bom

Bill of Materials with hierarchical assembly structure and cost rollup from supplier quotes.

Cost Rollup Hierarchy Suppliers

Requirements Verification

tdt report rvm

Requirements Verification Matrix showing test coverage and verification status.

Coverage % Pass/Fail Gaps

Test Status

tdt report test-status

Test execution summary with pass/fail rates and recent failures list.

Pass Rate Recent Failures By Category

Open Issues

tdt report open-issues

Dashboard of open NCRs, CAPAs, and failed tests requiring attention.

NCRs CAPAs Failed Tests

Tolerance Report

tdt report tolerance

Summary of all tolerance stackups with Cpk, yield, and pass/fail results.

Cpk Values Yield % Critical Dims

Design Structure Matrix (DSM)

Visualize component dependencies and interactions. The DSM reveals architecture, identifies coupling issues, and helps optimize modularity.

Component Dependency Matrix

CMP@1 Housing	-	M,T	M		P
CMP@2 Shaft	M,T	-	M	M
CMP@3 Bearing	M	M	-
CMP@4 Seal		M		-
CMP@5 Cover	P				-

DSM Commands

# Generate DSM for entire project
$ tdt dsm

# DSM for specific assembly only
$ tdt dsm ASM@1

# Show only mate relationships
$ tdt dsm --rel-type mate

# Export to Graphviz DOT format
$ tdt dsm --output dot > architecture.dot
$ dot -Tpng architecture.dot -o architecture.png

# Show coupling metrics
$ tdt dsm --metrics
Coupling Metrics:
  CMP@1 Housing:  Fan-in: 2  Fan-out: 3  Coupling: 0.62
  CMP@2 Shaft:    Fan-in: 3  Fan-out: 3  Coupling: 0.75
  ...

# Detect dependency cycles
$ tdt dsm --cycles
⚠ Found 1 cycle: CMP@1 → CMP@2 → CMP@3 → CMP@1

FMEA Report Example

The FMEA report aggregates all risks with RPN (Risk Priority Number) scoring and tracks mitigation status.

tdt report fmea

──────────────────────────────────────────────────────────────────────────
Summary: 5 risks | Avg RPN: 74 | High Risk (>100): 1 | Unmitigated: 0

Risk Priority:
  ■ Critical (RPN > 100): RISK@2
  ■ High (RPN 50-100): RISK@1, RISK@3
  ■ Medium (RPN < 50): RISK@4, RISK@5

Requirements Verification Matrix

Track verification status of every requirement. Essential for regulatory submissions and design reviews. Links tests to requirements automatically.
