Design compiler hierarchical synthesis

What are the inputs for synthesis?
What is Synthesis?
Synthesis is the process of converting RTL code, typically written in hardware description languages like Verilog or VHDL, into a gate-level netlist. Inputs : RTL, Technology libraries, Constraints (Environment, clocks, IO delays etc.)Outputs : Netlist , SDC, Reports etc..
What is design environment in synthesis?
Design environment: It consists of Operating Conditions, Wire Load Models and System Interface requirements.
Operating Conditions: It consists of Process, voltage and temperature requirements.
The effect each of these can have on the chip need to be considered during synthesis and timing analysis..
What is grouping and ungrouping in synthesis?
The group and ungroup commands provide the designer with the capability of altering the partitions in DC, after the design hierarchy has already been defined by the previously written HDL code..
What is the RTL synthesis process?
Synthesis is process of transferring higher level of abstraction (RTL) to implementable lower level of abstraction .
It is the process of transforming RTL to gate-level netlist.
Synthesis process can be optimized for Speed(timing)/Area/Testability (DFT)/Power(DFP)/Run time..
Design Compiler\xae RTL synthesis solution enables users to meet today's design challenges with concurrent optimization of timing, area, power and test.
In other words, It is a process of combining pre-existing elements to form something new.
It is the conversion of an idea into an implementation.
Logic Synthesis is combining primitive logic functions to form a design netlist that meets functional and design goals.
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.

This paper will compare area, speed, and compile time for several large designs using a variety of hierarchical compile strategies: top-down compile, top-down

Does design compiler optimize synthesis?

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? .

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.

What is a synthesis compile strategy?

• Compile Strategies Provides information about top-down, bottom-up, and mixed compile strategies Partitioning for Synthesis Partitioning a design effectively can enhance the synthesis results, reduce compile time, and simplify the constraint and script files.

What is the Synopsys design compiler?

About This Manual The Synopsys Design Compiler®tool provides basic synthesis information for users of the Design Compiler tools.
This manual describes synthesis concepts and commands, and presents examples for basic synthesis strategies.
