After compilation, rigorous analysis is required to verify the quality of results. | Error Message | Likely Cause | 2021

| Error Message | Likely Cause | 2021 Solution | | :--- | :--- | :--- | | Library 'typical' does not contain cell 'AND2X1' | Missing link library or wrong view. | Check report_lib typical . Use list_libs to verify. | | No constrained paths found | Clock not reaching flip-flops. | Run check_timing . Ensure create_clock uses correct get_ports . | | Timing loop detected | Combinational feedback without cut. | Use set_disable_timing on the specific false path, or restructure RTL. | | Compile_ultra license checkout failed | License server issue. | Ensure your LM_LICENSE_FILE points to 2021 license strings. Use compile instead of compile_ultra as fallback. |

Do you have a specific or library file you're trying to synthesize right now?

The synthesis execution flow follows five discrete phases. These commands are executed within the Design Compiler shell ( dc_shell ).
