Why do we need Verilog?
Verilog is a Hardware Description Language; a textual format for describing electronic circuits and systems. Applied to electronic design, Verilog is intended to be used for verification through simulation, for timing analysis, for test analysis (testability analysis and fault grading) and for logic synthesis.
How is Verilog different from high level language?
Verilog, just like VHDL, is meant to describe hardware. Instead, programming languages such as C or C++ provide a high level description of software programs, that is, a series of instructions that a microprocessor executes.
How does high-level synthesis work?
High level synthesis (HLS) [1], also known as behavioral synthesis and algorithmic synthesis, is a design process in which a high level, functional description of a design is automatically compiled into a RTL implementation that meets certain user specified design constraints.
What is high-level synthesis in VLSI?
High Level Synthesis (HLS) can be defined as the automated designing process that transforms the behavioral or functional description of the design into a digital hardware implementation.
Is Verilog or VHDL easier?
VHDL is strongly typed. This makes it harder to make mistakes as a beginner because the compiler will not allow you to write code that is in valid. Verilog is weakly typed. This makes it easier for someone who knows C well to read and understand what Verilog is doing.
How does Verilog differ from SystemVerilog?
The main difference between Verilog and SystemVerilog is that Verilog is a Hardware Description Language, while SystemVerilog is a Hardware Description and Hardware Verification Language based on Verilog. Verilog is an HDL while SystemVerilog is an HDL as well as HVL. Overall, SystemVerilog is a superset of Verilog.
Can C/C++ do what Verilog does?
So, simply C/C++ cannot do what Verilog does. Verilog is used to describe/design the low level HW. Synthesis is run on this code which directly translates it into gate level circuitry. The most predominant aspect of such a language is concurrence; or parallel execution.
Why is HLS so slow?
The language wars between VHDL and Verilog versus C-based dialect, and then SystemC and SystemVerilog, slowed everything down.” That limited HLS’ potential. “There was another class of HLS that we call application specific instruction set processors (ASIP),” said Paulin.
What is the best approach to implement a new HLS solution?
HLS works well with a modular design approach. It can produce IPs and with the right interface naturally fit into the IP reuse and creation strategy.” Sean Dart, senior group director for R&D in Cadence, focused on the quality and flexibility of implementation.
What is the future of high-level synthesis?
HLS is beginning to solve some problems that were not originally anticipated. High-level synthesis is getting yet another chance to shine, this time from new markets and new technology nodes. But it’s still unclear how fully this technology will be used.
