The tee command mirrors the tool output onto your screen while simultaneously saving it to a log file for review. To help tailor future steps, tell me:

To execute this script in batch mode via your linux terminal command line, run: dc_shell -f run_synthesis.tcl | tee synthesis_run.log Use code with caution. synopsys design compiler tutorial 2021

Keep your top-level module purely structural. It should only instantiate sub-modules. This structure helps Design Compiler optimize sub-blocks efficiently.

report_power -analysis_effort high > reports/power.rpt It should only instantiate sub-modules

set_output_delay -max 0.5 -clock core_clk [get_ports dout*] set_output_delay -min 0.1 -clock core_clk [get_ports dout*]

# Check for missing constraints or design inconsistencies before compiling check_design > ../reports/check_design_pre_compile.rpt # Standard Compilation compile # ALTERNATIVE: High-effort optimization for tight timing budgets # compile_ultra -no_autoungroup # ALTERNATIVE: Running in Topographical Mode (Requires physical libraries/DEF/LEF) # compile_ultra -topographical Use code with caution. Phase 4: Generating and Analyzing Reports Phase 4: Generating and Analyzing Reports The synthesis

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

report_area -hierarchy > $report_dir/area.rpt report_power -analysis_effort high > $report_dir/power.rpt

Once constraints are applied, you run the optimization engine. For basic designs, the structural compilation is straightforward. For advanced designs, explicit architectural flags are passed.
