Non-Project Mode Example Script - 2022.1 English

Vivado Design Suite User Guide: Implementation (UG904)

Document ID
Release Date
2022.1 English

The following script is an example of running implementation in Non-Project Mode. Assuming the script is named run.tcl, you would call the script using the source command in the Tcl shell.

Note: The read_xdc step reads XDC constraints from the XDC files and applies constraints to design objects. Therefore all netlist files must be read into Vivado and link_design should be run before read_xdc to ensure that the XDC constraints can be applied to their intended design objects.
source run.tcl

# Step 1: Read in top-level EDIF netlist from synthesis tool read_edif c:/top.edf
# Read in lower level IP core netlists read_edif c:/core1.edf
read_edif c:/core2.edf

# Step 2: Specify target device and link the netlists
# Merge lower level cores with top level into single design link_design -part xc7k325tfbg900-1 -top top

# Step 3: Read XDC constraints to specify timing requirements read_xdc c:/top_timing.xdc
# Read XDC constraints that specify physical constraints such as pin locations read_xdc c:/top_physical.xdc

# Step 4: Optimize the design with default settings opt_design

# Step 5: Place the design using the default directive and save a checkpoint # It is recommended to save progress at certain intermediate steps
# The placed checkpoint can also be routed in multiple runs using different options place_design -directive Default
write_checkpoint post_place.dcp

# Step 6: Route the design with the AdvancedSkewModeling directive. For more information
# on router directives type 'route_design -help' in the Vivado Tcl Console route_design -directive AdvancedSkewModeling

# Step 7: Run Timing Summary Report to see timing results report_timing_summary -file post_route_timing.rpt
# Run Utilization Report for device resource utilization report_utilization -file post_route_utilization.rpt

# Step 8: Write checkpoint to capture the design database;
# The checkpoint can be used for design analysis in Vivado IDE or TCL API
write_checkpoint post_route.dcp
