You can use read_verilog or the modern analyze and elaborate flow. The latter is preferred as it allows for better error checking and parameter passing.

Defining Design Constraints synopsys design compiler tutorial 2021
The design challenges of the late 2010s and early 2020s forced significant advancements in synthesis tools. The 2021-era Design Compiler was focused on predictability, low power, and deep sub-micron nodes (like 5nm and below).
