Design compiler bottom up synthesis

  • What is ungrouping in synthesis?

    Removing a level of hierarchy is called ungrouping.
    Ungrouping removes (or collapses) the level of hierarchy of the identified subdesign and merges the subdesign with the surrounding logic..

  • Elaboration is the process that occurs between parsing and simulation.
    It binds modules to module instances, builds the model hierarchy, computes parameter values, resolves hierarchical names, establishes net connectivity, and prepares all of this for simulation.

How do I synthesize a design and compile?

Refer Chap. 19 for the SDC commands.
To synthesize the design and to compile, use the script shown in Example 1.
The strategy used during the compilation of any design can be top-down or bottom-up compilation.
Each compilation strategy has its own advantages and disadvantages.

How to perform a block-level synthesis?

1.
Perform the synthesis for the different clock groups. 2.
Use the bottom-up synthesis and extract the block-level constraints. 3.
Optimize the design during block-level synthesis to meet the area and speed. 4.
Specify the top-level constraints. 5.
Perform the top-level synthesis and optimize the design to meet the top-level constraints. 6.

What is Synopsys design compiler?

Synopsys Design Compiler is industry leading logic synthesis tool and popular as Synopsys DC.
Most of the leading ASIC design companies uses the Synopsys DC during the logic synthesis and Synopsys PT for the timing analysis and timing closure.
The chapter focuses on the design constraints and optimization using Synopsys DC.
