Synopsys Design Compiler Tutorial 2021 Exclusive

After compilation finishes, you must inspect the structural quality of the netlist and save the generated hardware assets.

Synopsys Design Compiler Tutorial 2021: Complete Guide to RTL Synthesis

# 1. Setup source .synopsys_dc.setup

Use set_driving_cell on all input ports. DC 2021 is stricter about floating inputs. synopsys design compiler tutorial 2021

set_output_delay -clock clk -max 2.5 [get_ports data_out*]

The analyze command checks the RTL for syntax errors and builds intermediate files in the WORK directory. The elaborate command builds the generic GTECH architecture and allows parameter overriding.

Real-world chips operate under specific physical conditions. You must define these parameters before optimizing. After compilation finishes, you must inspect the structural

Constraints drive the optimization algorithms. Accurate constraints prevent the tool from under-optimizing or over-optimizing your hardware.

Constraints instruct Design Compiler on how to optimize the logic for real-world hardware environments. Save these rules in a Synopsys Design Constraints ( .sdc ) file format.
