Logic synthesis transforms an abstract behavioral description (written in Verilog, SystemVerilog, or VHDL) into a structural gate-level implementation. This process is constraint-driven, meaning the tool optimizes the logic to meet specific timing, area, and power goals. Synthesis consists of three main steps:
# Define a clock named 'sys_clk' on port 'clk' with a 10ns period (100 MHz) create_clock -name sys_clk -period 10.0 [get_ports clk] # Model clock jitter, skew, and margin (Timing Uncertainty) set_clock_uncertainty 0.3 [get_clocks sys_clk] # Model the rise and fall transition times of the clock edge set_clock_transition 0.15 [get_clocks sys_clk] Use code with caution.

Before diving into the synthesis commands, you must create a stable and correctly configured working environment. This involves setting up tool-specific configuration files and environment variables. : The command-line interface
