我刚学Verilog,说的自然是砖。说得可能不中听,会引来板砖,所以很机智地没有开放评论。请看代码和注释: //User Defined Primitivesprimitivexor_cell_level(outputc,inputa,inputb);table//truth table//a b c11:0;01:1;10:1;00:0;endtableendprimitive//Switch level is the lowest level of abstraction pr...
the development of language-based methods for design and verification of electronics, from the emergence of the first nonproprietary hardware description languages (HDLs) in the mid-'80s to the current movement to higher levels of abstraction typified by the new languages-SystemC and SystemVerilog. ...
Many expect that the same approach could be effectively adapted at higher levels of abstraction. In the SoCs context, the traditional IC design methodology relying on EDA tools used in a two stages design flow - a VHDL/Verilog RTL specification, followed by logical and physical synthesis - is ...
Check the correctness of RTL against your High-Level models using SLEC. Enabling proof that specification and implementation are identical despite differences in language, timing, or abstraction. High-level Verification Questa HL-SystemC High-level design verification with Questa HL-SYC expansion helps ...
The Catapult High-Level Synthesis Platform empowers designers to use industry-standard ANSI C++ and SystemC to describe functional intent and move up to a more productive abstraction level.
It is apparent to the point of being self-evident that when the source code of a design is created, there will be fewer errors if the source is at a higher abstraction level than if it is at a lower level. However, there is still a process required to verify the transformations which...
Designs at the logic level of abstraction, describe a digital circuit in terms of primitive logic functions such as or, and nor, etc., and allow for the nets interconnecting the logic functions to carry 0,1, x and z values. At the analog-transistor level of modeling, we use an electroni...
Verification environment should be re-usable at different levels of abstraction 3. Technical Details 3.1. Verification Environment Overview: Figure:1 Block Diagram: Verification Environment 3.2. Details of the verification components: The verification environment is built using OVM methodology [1]. OVM en...
The Role of RTL in Integrated Circuit Design The modern integrated circuit (IC) design flow involves taking a specification for what the device needs to do and turning it into a packaged semiconductor chip. The level of abstraction that RTL design delivers enables engineers to concentrate on the...
High-level synthesis is the process of converting a high-abstraction-level description of a design to a register-transfer-level (RTL) description for input to traditionalASIC and FPGA implementationworkflows. This high-level design description can be expressed in high-level languages such as C, C++...
