When a wire has multiple drivers, the wire's (readable) value is resolved by a function of the source drivers and their strengths. A subset of statements in the Verilog language are synthesizable. Verilog modules that conform to a synthesizable coding style, known as RTL (register-transfer level), can
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 ...
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.
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.
The functions implemented in Foreign language can be called from SystemVerilog and such functions are called Import functions. Similarly, functions implemented in SystemVerilog can be called from Foreign language (C/C++ or System C); such functions are called Export functions. DPIs allow transfer of data between two domains through function ...
A bus functional model (BFM), also known as a transaction verification model (TVM) is a non-synthesizable software model of an integrated circuit component having one or more external buses. The emphasis of the model is on simulating system bus transactions prior to building and testing the actual hardware.
The netlist is a Boolean-algebra representation of the IP's logical function implemented as generic gates or process-specific standard cells. An IP core implemented as generic gates can be compiled for any process technology. A gate-level netlist is analogous to an assembly code listing in the field of computer programming. A netlist gives the ...
Verilator converts synthesizable Verilog to C++, while C++ library could be compiled into a MEX file using MATLAB interface to C++. This is how Verilog designs can be directly simulated from MATLAB. Using compiled C++ models with MATLAB is faster than using co-simulation interfaces with a separate hardware description language (HDL) simulator ...
