Vivado Implementation Runbook

1. Implementation Phases & Directives

Phase	Directives (Ascending Intensity)
opt	Default, Explore, ExploreWithRemap, AggressiveExplore
place	Default, WLDrivenPlacement, AltSpreadLogic_high, ExtraNetDelay_high
phys_opt	Default, Explore, AggressiveExplore, AlternativeFlowWithRetiming
route	Default, Explore, AggressiveExplore, MoreGlobalIterations

2. Implementation Execution

open_checkpoint /tmp/vivaclaw_post_synth.dcp
opt_design -directive <dir>
place_design -directive <dir>
phys_opt_design -directive <dir>
route_design -directive <dir>
write_checkpoint -force /tmp/vivaclaw_post_route.dcp

3. Partial Re-route (Fast Fix)

If only a few nets are failing:

route_design -unroute -nets [get_nets -hierarchical <pattern>]
route_design -directive AggressiveExplore -nets [get_nets -hierarchical <pattern>]

4. Incremental Flow

If a previous high-quality run exists:

read_checkpoint -incremental reference.dcp
place_design
route_design

Check get_property INCREMENTAL_REUSE [current_design] to verify reuse % (>90% ideal).

vivado-flow

devansh0703/vivaclaw-agent

Run a complete Vivado FPGA design flow from RTL sources to bitstream. Use when asked to synthesize, implement, build, or compile an FPGA design. Also handles project creation, checkpoint management, and run orchestration.

vivado-cdc

devansh0703/vivaclaw-agent

Analyze and fix clock domain crossing violations. Use when CDC violations appear, when auditing multi-clock designs, or when reviewing set_false_path and set_max_delay exceptions for safety.

vivado-constraints

devansh0703/vivaclaw-agent

Author and audit Vivado XDC constraint files. Use when creating constraints, finding unconstrained paths, debugging timing exceptions, checking clock definitions, or auditing I/O delays for completeness.

2026-04-223

vivado-debug

devansh0703/vivaclaw-agent

Insert ILA and VIO debug cores into a Vivado design. Use when asked to add hardware debug probes, set up ILA trigger conditions, insert VIO for stimulus injection, or generate .ltx probeinfo files.

vivado-floorplan

devansh0703/vivaclaw-agent

Create Pblock floorplan constraints in Vivado. Use when dealing with placement congestion, SSI multi-die devices, reconfigurable partitions (DFX), or when critical paths need physical locality.
