Verilog, standardized as IEEE 1364, is a hardware description language (HDL) ... A subset of statements in the Verilog language are synthesizable.
Using high-level synthesis, also known as ESL synthesis, the allocation of work to clock cycles and across structural components, such as floating-point ALUs, is done by the compiler using an optimisation procedure, whereas with RTL logic synthesis (even from behavioural Verilog or VHDL, where a thread of execution can make multiple reads and ...
Just-in-Time Verilog simulator and compiler for FPGAs allowing to instantly run both synthesizable and unsynthesizable Verilog on hardware CVC Perl style artistic license [3] Tachyon Design Automation V2001, V2005 CVC is a Verilog HDL compiled simulator. CVC has the ability to simulate in either interpreted or compiled mode. GPL Cver: GPL
Icarus Verilog *BSD, Linux, Mac: GPL-2.0-or-later: Verilog simulator Verilator: Posix: LGPL-3.0-only or Artistic-2.0: Verilator is the fastest free Verilog HDL simulator. It compiles synthesizable Verilog into cycle accurate C++ or SystemC code following 2-state synthesis (zero delay) semantics.
High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior.
Therefore, Verilog is a subset of SystemVerilog. SystemVerilog for verification uses extensive object-oriented programming techniques and is more closely related to Java than Verilog. These constructs are generally not synthesizable. The remainder of this article discusses the features of SystemVerilog not present in Verilog-2005.
A synthesizable CPU core, it was for many years maintained by developers at OpenCores.org, although, since 2015, that activity has now been taken over by the Free and Open Source Silicon Foundation at the librecores.org website. The Verilog RTL description is released under the GNU Lesser General Public License (LGPL).
Register-transfer-level abstraction is used in hardware description languages (HDLs) like Verilog and VHDL to create high-level representations of a circuit, from which lower-level representations and ultimately actual wiring can be derived. Design at the RTL level is typical practice in modern digital design.
