Never trust synthesis without reports. Run these immediately after compile_ultra .

Missing else or default statements in combinatorial always blocks.

echo "Starting compile_ultra at [date]" compile_ultra -timing_high_effort -area_high_effort echo "Synthesis finished at [date]" synopsys design compiler tutorial 2021

The final output is a gate-level netlist and an updated SDC file, which are then passed to Place and Route (P&R) tools like .

set_clock_latency -max 0.6 [get_clocks clk] Never trust synthesis without reports

Mapping GTECH to specific cells from your Target Library.

Logic synthesis converts your abstract hardware descriptions (written in Verilog, SystemVerilog, or VHDL) into a physical gate-level realization. Design Compiler performs three primary functions: synopsys design compiler tutorial 2021

This is the most critical user-input step. You provide DC with its goals. These are divided into two categories:
