Design Compiler is entirely constraint-driven. Without realistic constraints, the tool may produce an excessively large layout or fail to meet operational speeds. Constraints are specified using Synopsys Design Constraints (SDC) syntax. Clock Constraints

Exporting the Gate-Level Netlist

To help refine this implementation, could you provide more context? Tell me: Your (e.g., 65nm, 28nm, 7nm). Any specific power optimization goals (like clock-gating). # Model the driving strength of an external

Verify if your timing constraints passed or failed, and check the total cell area used.

Or run in batch mode from the Linux shell:

# Define search paths set search_path [concat [list . ./src ./libs] $search_path] # Specify the technology libraries set target_library [list typical.db] set link_library [list * typical.db dw_foundation.sldb] set symbol_library [list typical.sdb] # Define administrative settings set synopsys_program_name "design_compiler" Use code with caution. 3. The Design Compiler User Interfaces Step 1: Reading the RTL Source Code #

To help refine this process for your specific design, let me know: What (e.g., 65nm, 28nm) are you targeting?
