WebI read the RTL compiler user mannual. There is only one line explaining the meaning of "area": "The area report gives a summary of the area of each component in the current design. The report gives the number of gates and the area size based on the specified technology library. Levels of hierarchy are indented in the report."

In the second case an additional error message indicating the exact nature of the
WebMar 18, 2024 · Design Compiler tries to optimize both of them as long as the constraints (e.g. dont_touch) and synthesis options (ungrouping, boundary optimization etc.) permit. DC also has an option for the optimization strategy, I'll show below. If it optimizes the design as a whole, is there an advantage to synthesizing smaller modules first? WebI keep trying to solve the real-world problems with these skills in hand, so that I face the different challenges. ... power and timing reports using …
