Before launching Design Compiler, the environment must be configured correctly. This involves pointing the tool to the technology libraries (standard cell libraries) and setting up the license.
This is the most critical report. It shows the longest path (Critical Path) in the design. synopsys design compiler tutorial 2021

Before diving into the CLI, let’s establish why the 2021 release matters for the modern designer. Before launching Design Compiler, the environment must be
| Action | Command |
|--------|---------|
| Check design | check_design |
| Show clock | report_clock |
| Reset design | remove_design -all |
| Change naming rule | define_name_rules ... |
| Ungroup hierarchies | ungroup -flatten -all |
| Set max area | set_max_area 0 |
| Set max fanout | set_max_fanout 20 [current_design] | Before diving into the CLI, let’s establish why
The standard compile command performs logic optimization and technology mapping.
