To run the script, you would launch dc_shell and type:
For over three decades, (often abbreviated as dc_shell ) has remained the gold standard for RTL synthesis. If you are an ASIC or FPGA designer, mastering this tool is non-negotiable. While newer versions (2022, 2023, 2024) have added incremental features like better multicore support and cloud integration, the 2021 release represents a mature, stable, and widely adopted version in many production tape-outs.

Use check_design before compiling to find unconnected wires or multiple drivers.
Ensure that multi-instantiated blocks are correctly managed by using the uniquify command (automatically handled in compile_ultra ) to allow custom optimization based on the distinct physical context of each instance. To run the script, you would launch dc_shell
