The IEEE 1800-2005 SystemVerilog standard[1] defines the syntax and simulation semantics of these extensions, but does not define which constructs are synthesizable, or the synthesis rules and semantics. This paper proposes a standard synthesis subset for SystemVerilog. The paper reflects discussions ...
In my previous post aboutSystemVerilog and Verilog X Optimism – You May Not Be Simulating What You Think, I discussed what is Verilog X optimism, and some coding styles that are prone to Verilog X optimism bugs. So how do you avoid potential bugs that Verilog X optimism can introduce? On...
Descriptions of digital circuits expressed in high-level languages such as Verilog are automatically “compiled” into the logic elements needed to implement these functions. This is called logic synthesis and is another example of this process. The entire collection of design elements is then placed...
IEEE defines both Verilog and VHDL as industry standards. Here’s a simple example of an AND gate in both languages. An AND gate has two inputs and one output. If the inputs are both equal to 1, the output is 1. If they are not equal or if both are set to 0, the output is...
Simulation models for the Hard-IP such as the PowerPC processor, MGT, and PCIe leverage this technology. For more information, see theSynthesis and Simulation guideat: http://www.xilinx.com/support/documentation/dt_ise.htm There are special requirements for licensing which are also listed in th...
In the world of FPGA design, understanding the components is crucial. Let’s dive into the intricate elements that make up an FPGA and how they contribute to its functionality. First and foremost, we have the programmable logic blocks (PLBs). These are like the brain cells of the FPGA, ...
Among the challenges of writing HDL is the requirement of being an expert in all of areas of the language. In addition, the VHDL language, which may be used with SystemVerilog components, has its own separate syntax. SystemVerilog and VHDL are both known as compiled languages. In other word...
2.2.2 高层次综合(High-Level Synthesis) 后者,提高设计的抽象程度的例子是高层次综合(High-Level Synthesis,HLS),是指把高层次语言例如C++、Python、Matlab,通过编译器,解析、优化、转化为低层次语言例如Verilog/VHDL。因为大多数应用,在算法层面,已经有许多软件工程师提供了完善且优秀的代码,例如OpenCV、PyTorch等等,...
