: Reads your Verilog or VHDL files and checks for syntax errors.

Design Compiler transforms abstract RTL into structural gate-level representations. The 2021 synthesis flow focuses on:

Constraints tell Design Compiler how fast the circuit needs to run and how much physical space it can occupy. These constraints are typically written using Synopsys Design Constraints (SDC) syntax.

set_input_delay -max 2.0 -clock clk [remove_from_collection [all_inputs] [get_ports clk]] set_output_delay -max 2.0 -clock clk [all_outputs]

The synthetic_library for DesignWare is crucial. If you miss this, your multiplier or ALU synthesis will fail.

Applies logic minimization, restructuring, and technology mapping based on user constraints.

Compile the design. The 2021 version heavily utilizes the ( -map_effort high ) to accurately estimate wire loads. : Reads your Verilog or VHDL files and

What (e.g., 65nm, 28nm, 7nm) are you targeting?

Note: For the most accurate 2021 behavior, refer to the official dc_shell user guide: dc_ug.pdf (version M-2017.03-SP3 through 2021.09).
