Vivado Design Analysis & Timing Closure Guide

Based on UG906 (v2025.2). This skill helps interpret analysis reports and make timing closure decisions. For complete command syntax, see REFERENCE.md. For TCL execution, use vivado-tcl. For constraint changes, use vivado-constraints. For implementation strategies, use vivado-impl.

Timing Path Fundamentals

Four common path types:

1. Input Port → Register       (constrained by set_input_delay)
2. Register → Register         (constrained by clock period)
3. Register → Output Port      (constrained by set_output_delay)
4. Input Port → Output Port    (combinational, set_max_delay)

Path structure (three sections):

Source Clock Path → Data Path → Destination Clock Path
(clock source      (launch pin    (clock source
 to launch cell)    to capture     to capture
                    cell input)    cell)

Slack formula:

Max delay (Setup/Recovery): slack = data_required_time - data_arrival_time
Min delay (Hold/Removal): slack = data_arrival_time - data_required_time

Max/Min Delay Analysis Corner Selection

Analysis Type	Source Clock	Data Path	Destination Clock
Setup/Recovery (max delay)	Slow_max	Slow_max	Slow_min
Setup/Recovery (max delay)	Fast_max	Fast_max	Fast_min
Hold/Removal (min delay)	Slow_min	Slow_min	Slow_max
Hold/Removal (min delay)	Fast_min	Fast_min	Fast_max

Key rule: Delays from different corners are NEVER mixed on same path during slack calculation.

Report Selection Guide

Goal	Command	When to Use
Quick timing signoff	`report_timing_summary`	After implementation, mandatory before bitstream
Analyze specific paths	`report_timing -from/-to/-through`	Debugging specific failing paths
Overall QoR score (1-5)	`report_qor_assessment`	After routing, assess closure likelihood
Auto optimization hints	`report_qor_suggestions`	When stuck on timing closure
Path characteristics	`report_design_analysis`	Deep analysis of logic levels, fanout, physical spread
Methodology compliance	`report_methodology`	Early in flow to catch methodology violations
Resource usage	`report_utilization`	After synthesis or implementation
CDC checks	`report_cdc`	After synthesis, verify clock domain crossings
Congestion analysis	`report_design_analysis -congestion`	After placement, if timing degraded
Design rule checks	`report_drc`	Before bitstream generation
Bus skew	`report_bus_skew`	If set_bus_skew constraints exist (NOT in report_timing_summary)

Timing Closure Decision Tree

Setup Violation Resolution

Setup violation detected
  ├─ Check Logic Levels (report_design_analysis)
  │   └─ High logic levels → Pipeline registers / retiming (vivado-synth: -global_retiming)
  ├─ Check Fanout (report_design_analysis)
  │   └─ High fanout → MAX_FANOUT attribute / phys_opt replication (vivado-impl)
  ├─ Check Physical Spread (report_design_analysis -congestion)
  │   └─ Large bounding box → Pblock floorplanning (vivado-constraints)
  ├─ Check Clock Skew
  │   └─ Negative skew → Review clock tree, BUFG placement
  └─ Check Timing Exception
      └─ Missing/wrong constraint → Fix in XDC (vivado-constraints)

Hold Violation Resolution

Hold violation detected
  ├─ Check fast-corner delay
  │   └─ Very short data path → Add delay cells (phys_opt_design hold fix)
  ├─ Check Clock Skew
  │   └─ Large positive skew → Review clock tree balance
  └─ Check Inter-SLR paths (SSI devices)
      └─ SLR crossing → SLR-aware placement (vivado-impl)

Congestion Mitigation

Congestion Level ≥ 5
  ├─ Check utilization (report_utilization)
  │   └─ > 80% LUT → Reduce design size or use area-optimized synthesis
  ├─ Check high-fanout nets
  │   └─ Replicate drivers (phys_opt_design fanout optimization)
  ├─ Try congestion-focused strategies
  │   └─ vivado-impl: Congestion_* strategies
  └─ Floorplanning
      └─ Spread logic across device (Pblocks, vivado-constraints)

Message Severity Levels

Severity	Meaning	Action Required
Status	General processing feedback	None
Info	Process/design feedback	None
Warning	Constraints not applied as intended, sub-optimal results possible	Review
Critical Warning	Input/constraints failing best practices, often leads to errors	Fix recommended

Based on UG906 (v2025.2). This skill helps interpret analysis reports and make timing closure decisions. For complete command syntax, see REFERENCE.md. For TCL execution, use vivado-tcl. For constraint changes, use vivado-constraints. For implementation strategies, use vivado-impl.

## Timing Path Fundamentals

Four common path types:
```
1. Input Port → Register       (constrained by set_input_delay)
2. Register → Register         (constrained by clock period)
3. Register → Output Port      (constrained by set_output_delay)
4. Input Port → Output Port    (combinational, set_max_delay)
```

Path structure (three sections):
```
Source Clock Path → Data Path → Destination Clock Path
(clock source      (launch pin    (clock source
 to launch cell)    to capture     to capture
                    cell input)    cell)
```

Slack formula:
- **Max delay (Setup/Recovery):** `slack = data_required_time - data_arrival_time`
- **Min delay (Hold/Removal):** `slack = data_arrival_time - data_required_time`

## Max/Min Delay Analysis Corner Selection

| Setup/Recovery (max delay) | Slow_max | Slow_max | Slow_min |
| Setup/Recovery (max delay) | Fast_max | Fast_max | Fast_min |
| Hold/Removal (min delay) | Slow_min | Slow_min | Slow_max |
| Hold/Removal (min delay) | Fast_min | Fast_min | Fast_max |

**Key rule:** Delays from different corners are NEVER mixed on same path during slack calculation.
