set_output_delay -max 0.8 -clock clk [all_outputs]
Inside the GUI, you can load your setup via File -> Read or execute commands directly inside the built-in console window. 5. Troubleshooting Common Synthesis Warnings Warning Code / Issue Root Cause Mitigation Strategy
Below is a template you can use to run synthesis in batch mode.
set_driving_cell -lib_cell FD1 -pin Q [get_ports data_in]
For the digital designer, mastering DC 2021 means mastering the transition from abstract behavior to concrete silicon—one Tcl command at a time.
The synthesis process can be broken down into five distinct stages:
report_area -hierarchy
Before launching DC, you must define your library paths. This is typically done in a .synopsys_dc.setup file in your home directory or project folder.
set_output_delay -max 0.5 -clock core_clk [get_ports dout*] set_output_delay -min 0.1 -clock core_clk [get_ports dout*]
Constraints instruct Design Compiler on your performance goals. These commands mimic Synopsys Design Constraints (SDC) syntax.

# -hierarchy keeps the hierarchy if not ungrouped write -format verilog -hierarchy -output netlist/my_design_netlist.v
