# Vivado TCL Script Generation Guide
## Overview
This skill generates Vivado TCL scripts and executes them via `vivado -mode batch`. It covers the full FPGA design flow: project creation, synthesis, implementation, bitstream generation, hardware programming, IP integration, debug, and simulation. For the complete command reference, see REFERENCE.md.
## Critical Rules
1. **NEVER mix Project Mode and Non-Project Mode commands** — they are incompatible flows
2. **Project Mode**: uses `create_project`, `add_files`, `launch_runs`, `wait_on_run`, `open_run`
3. **Non-Project Mode**: uses `read_verilog`, `synth_design`, `opt_design`, `place_design`, `route_design`
4. **Always ask the user which mode they want** if not obvious from context
5. **This skill only generates/executes TCL** — do NOT attempt to parse or analyze Vivado reports or logs
## Execution Model
### How to run a TCL script
```bash
# Batch mode (recommended for automation)
vivado -mode batch -source <script.tcl>
# With arguments
vivado -mode batch -source script.tcl -tclargs "ARG1=value1"
# Interactive TCL shell
vivado -mode tcl
```
### Key output files
- `vivado.log` — full session log
- `vivado.jou` — journal of TCL commands (reusable as script)
- `*.dcp` — design checkpoints (snapshots of design state)
- `*.bit` — bitstream files
- `*.xsa` — hardware platform for Vitis
- `*.ltx` — debug probes file
## Quick Reference: Project Mode Flow
```tcl
# 1. Create project
create_project <name> <dir> -part <part>
# 2. Add sources
add_files {./src/top.v ./src/sub.v}
add_files -fileset constrs_1 ./constraints/timing.xdc
update_compile_order -fileset sources_1
# 3. Synthesis
launch_runs synth_1
wait_on_run synth_1
# 4. Open synth results & reports
open_run synth_1 -name netlist_1
report_timing_summary -file syn_timing.rpt
report_power -file syn_power.rpt
# 5. Implementation + bitstream
launch_runs impl_1 -to_step write_bitstream
wait_on_run impl_1
# 6. Reports
open_run impl_1
report_timing_summary -file imp_timing.rpt
report_utilization -file imp_util.rpt
report_power -file imp_power.rpt
```
## Quick Reference: Non-Project Mode Flow
```tcl
# 0. Setup
set outputDir ./output
file mkdir $outputDir
# 1. Read sources
read_verilog {./src/top.v ./src/sub.v}
read_xdc ./constraints/timing.xdc
# 2. Synthesis
synth_design -top <top_module> -part <part>
write_checkpoint -force $outputDir/post_synth.dcp
report_timing_summary -file $outputDir/post_synth_timing.rpt
# 3. Implementation
opt_design
place_design
# Optional: phys_opt_design
route_design
write_checkpoint -force $outputDir/post_route.dcp
# 4. Reports
report_timing_summary -file $outputDir/post_route_timing.rpt
report_utilization -file $outputDir/post_route_util.rpt
report_power -file $outputDir/post_route_power.rpt
report_drc -file $outputDir/post_route_drc.rpt
# 5. Generate bitstream
write_bitstream -force $outputDir/top.bit
```
## IP Integrator (Block Design)
```tcl
# Create block design
create_bd_design "system"
# Add IP cores
create_bd_cell -type ip -vlnv xilinx.com:ip:<ip_name>:<version> <instance>
# Run automation (AXI connections, external ports)
apply_bd_automation -rule xilinx.com:bd_rule:processing_system7 \
-config {make_external "FIXED_IO, DDR"} [get_bd_cells ps7_0]
apply_bd_automation -rule xilinx.com:bd_rule:axi4 \
-config {Master "/ps7_0/M_AXI_GP0"} [get_bd_intf_pins peripheral/S_AXI]
# Validate, save, generate wrapper
assign_bd_address
validate_bd_design
save_bd_design
make_wrapper -files [get_files system.bd] -top
# Export for Vitis
write_hw_platform -fixed -include_bit -force ./system_wrapper.xsa
```
## Hardware Programming
```tcl
open_hw_manager
connect_hw_server -url localhost:3121
open_hw_target
current_hw_device [get_hw_devices <device>]
set_property PROGRAM.FILE {<bitstream>.bit} [current_hw_device]
set_property PROBES.FILE {<probes>.ltx} [current_hw_device]
program_hw_devices [current_hw_device]
close_hw_target
disconnect_hw_server
close_hw_manager
```
## Debug Core Insertion (ILA)
```tcl
# After synthesis, before implementation
open_run synth_1
# Create ILA
create_debug_core u_ila_0 ila
set_property C_DATA_DEPTH 1024 [get_debug_cores u_ila_0]
# Connect clock
set_property port_width 1 [get_debug_ports u_ila_0/clk]
connect_debug_port u_ila_0/clk [get_nets clk]
# Add probes
set_property port_width <width> [get_debug_ports u_ila_0/probe0]
connect_debug_port u_ila_0/probe0 [get_nets {<signal_list>}]
# Implement and write probes
implement_debug_core
write_debug_probes -force ./output/top.ltx
```
## TCL Syntax Tips
### Object queries
```tcl
get_cells -hierarchical -filter "lib_cell =~ FD*"
get_pins -of [get_cells inst_1]
get_nets -of [get_pins inst_1/D]
get_property loc [get_cells inst_1]
set_property loc SLICE_X1Y27 [get_cells inst_1]
```
### Bus indexing
```tcl
add_wave {bus[4]} ;# braces for square brackets
add_wave bus(4) ;# parentheses work too
```
### Error handling
```tcl
if {[catch {<command>} result]} {
puts "Error: $result"
}
```
## Workflow Guidelines
1. **Always write TCL to a `.tcl` file first**, then execute with `vivado -mode batch -source`
2. **Include `file mkdir` for output directories** to avoid errors
3. **Use `write_checkpoint`** at key stages in Non-Project Mode for recovery
4. **Add `report_timing_summary`** after synthesis and after routing — timing closure is critical
5. **Use `-force` on write commands** to allow re-runs without manual cleanup
6. **For IP Integrator flows**, always `validate_bd_design` before proceeding
7. **When programming hardware**, always check device connection before programming

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Copies are not installs. Installation counts require a reported successful installation; they are not a blanket quality guarantee.
