Synopsys Design Compiler Tutorial 2021 Today

set DESIGN_NAME "my_processor_top"

Power Compiler, an option within DC, provided advanced leakage power optimization. In deep sub-micron technologies, "leakage" power (current that flows even when a transistor is off) became a dominant factor. Power Compiler used techniques like multi-threshold voltage cell optimization and power-gating to dramatically reduce total chip power.

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

: The Graphical User Interface (GUI). Beginners often start here to visualize the schematic and timing paths. 3. The Core Synthesis Flow

Started using the dc_shell command. An interactive command-line interface based on Tcl. Ideal for executing commands step-by-step and testing script segments. Never trust synthesis without reports

Any specific you are encountering.

write -format verilog -hierarchy -output outputs/final_netlist.v

Contains visual representations of cells used for generating schematic views (usually .sdb files). Example .synopsys_dc.setup File Constraints create_clock -name clk -period 5 [get_ports clk]

This is where the magic happens. The 2021 release streamlined compile commands.

A typical .synopsys_dc.setup file may look like this:

# .synopsys_dc.setup set search_path [list . ./rtl ./libs ./scripts $search_path] set target_library [list typical.db] set link_library [list * typical.db ram_256x16.db] set symbol_library [list typical.sdb] define_design_lib WORK -path ./work Use code with caution. 3.
