While this tutorial covers the fundamentals, mastering Design Compiler requires deeper study. Here are resources that were popular in 2021 to help you on your journey.
Missing else or default statements in combinatorial always blocks.
The deadline by which the data must arrive to be reliably captured by the next clock edge, incorporating uncertainty margins and output delays.
If you are using -gui , type:
This was the new flagship product introduced in 2020 and fully established in 2021. It was built to handle the most advanced process nodes, down to 5nm and below. Key benefits included:
To make this flow practical and repeatable, everything is scripted in Tcl. A synthesis script, often named run_synthesis.tcl , automates all the steps we discussed. A typical script will:
set compile_ultra_ungroup_dw false # Keep datapath elements grouped synopsys design compiler tutorial 2021
Add explicit default assignments to prevent unwanted latch generation.
. It uses physical information from the floorplan to provide more accurate timing estimates, reducing the "correlation gap" between synthesis and physical placement. Looking for more VLSI tools?
Synopsys Design Compiler has a rich history, with several editions serving different design needs. As of 2021, the most relevant versions for a standard user were: The deadline by which the data must arrive
With your setup ready, you can launch Design Compiler in its shell mode. There are two primary ways:
cd work dc_shell -f ../scripts/synthesis.tcl | tee synthesis.log Use code with caution. Graphical User Interface (GUI) Mode
