The synth_design
command can be used in both Project Mode and
Non-Project Mode. It runs Vivado synthesis on RTL sources with
the specified options, and reads the design into memory after synthesis.

synth_design Example Script
The following is an excerpt from the create_bft_batch.tcl script found in the examples/Vivado_Tutorials directory of the software installation.
# Setup design sources and constraints
read_vhdl -library bftLib [ glob ./Sources/hdl/bftLib/*.vhdl ]
read_vhdl ./Sources/hdl/bft.vhdl
read_verilog [ glob ./Sources/hdl/*.v ]
read_xdc ./Sources/bft_full.xdc
# Run synthesis, report utilization and timing estimates, write design checkpoint
synth_design -top bft -part xc7k70tfbg484-2 -flatten rebuilt
write_checkpoint -force $outputDir/post_synth
For more information on using the synth_design
example script, see
the
Vivado
Design Suite Tutorial: Design Flows Overview (UG888) and the
Vivado
Design Suite User Guide: Synthesis (UG901).
The synth_design
example script reads VHDL and Verilog files, reads
a constraint file, and synthesizes the design on the specified part. The design is
opened by the Vivado tools into memory when
synth_design
completes. A design checkpoint is written after
completing synthesis.

Tcl
command, see
Vivado
Design Suite Tcl Command Reference Guide (UG835). This
reference guide also provides a complete description of the Tcl commands and their
options.
