What is a target library?

Distribution libraries contain all the elements, such as modules and macros, that are used as input for running your system. Target libraries contain all the executable code needed to run the system.

What is Synopsys library Compiler?

Synopsys requires a library file which describes the logic gates available for synthesis operations. This file contains logical descriptions and timing information for a set of logic gates (cells). …

What is Synopsys design vision?

Synopsys Design Vision is a logic synthesis tool. It will take HDL designs and synthesize them to gate-level HDL netlists. It can synthesize to generic gates or to other design libraries such as the vtvt_tsmc libraries or OSU standard cell libraries. The tool exists in a gui and command line version.

How do I use Synopsys compiler?

To compile into an optimized design: click on the Y=A+B icon to select it (the border becomes highlighted)…To view the schematic and plot it:

1. double-click on the Y=A+B icon to see your design’s symbol.
2. double-click on your design’s symbol to see its schematic.
3. select the File->Plot menu item.
4. click on OK.

What is link library and target library?

Target library(liberty file) is used when u need to build (during synthesis)or modify the netlist for the design(during APR). Link library is used to resolve the cell reference when design netlist is freezed.

What is VLSI target library?

link is the command used to resolve the functional references in your design. target_library is for mapping your design…your netlist after synthesis can and shall contain only cells from target library. so target is for mapping and link is for resolving functional references..

What is logic library in VLSI?

VLSI Guide 23:14 Design Setup No comments. Logical Libraries. It provides the timing and functionality information for all the standard cells (AND gate, OR gate, flip flops etc.) Provides the timing informations for hard macros like IP, ROM, RAM etc.

What is library in VLSI?

A library is a collection of cells that forms a consistent hierarchy. To enforce this consistency, Electric stores an entire library in one disk file that is read or written at one time. Only one library is the current one, and this sometimes affects commands that work at the library level.

What is Synopsys SpyGlass?

Synopsys VC SpyGlass integrates advanced algorithms and analysis techniques that provides designers detailed information and insights about their design much earlier in the RTL phase. VC SpyGlass is also natively integrated with Synopsys’ Verdi® automated debug system to accelerate root cause analysis for bugs.

What is link library and target library in VLSI?

What is DesignWare library?

DesignWare is a library that consists of high-level functional modules that allow a designer the flexibility to infer them in VHDL code. Apart from inferring DesignWare components, the designer can also instantiate these components.

What are shared library files?

A shared library is a file containing object code that several a. out files may use simultaneously while executing. When a program is link edited with a shared library, the library code that defines the program’s external references is not copied into the program’s object file. Instead, a special section called .

What is synthetic_library in designdesign compiler?

Design Compiler. The synthetic_library variable specifies the DesignWare library, which contains more complex cells. hardware description language (HDL) such as Verilog or VHDL. libraries during the synthesis process. (GTECH) library and DesignWare library. The GTECH library consists of basic logic gates and flip-flops.

What is the difference between rtlink library and target library?

Link library is used for linking the design. If there are some technology cells instantiated in the RTL such as memories, by providing link library the synthesis is able to map it to library cell and understand the interface Target library is used for technology mapping.

What is the use of link_library?

The link_library defines the i.e., cells in the link_library are not inferred by DC. For example, you may ROMs etc.) in the link_library list. This means that the user would synthesize linking to the pads and macros that are instantiated in the design. synthesize the core logic. shown in Example 3.1.

What is a target library in C++?

The “target library” usually specifies only the library with basic logic gates (the standard cells, not the IO pads or marcos).
