DC parses your HDL and creates an internal "GTECH" (generic technology) representation. In the high-stakes world of ASIC and FPGA
In the high-stakes world of ASIC and FPGA design, the bridge between RTL (Register-Transfer Level) fantasy and gate-level reality is synthesis. For over three decades, Synopsys’ has been that bridge—the de facto standard for logic synthesis. The 2021 release (part of the 2021.03-SP3 family) didn’t reinvent the wheel; instead, it sharpened the axe. This feature explores the critical updates, workflow optimizations, and a hands-on tutorial to get you from Verilog to a timing-closed netlist faster than ever. This feature explores the critical updates
Directories where DC looks for design files and libraries.
Once your constraints are defined, you can compile the design. Modern methodologies use Design Compiler Topographical mode ( compile_ultra ) to incorporate physical wire parasitics early, preventing timing mismatches during physical placement.
