Verilog-1995 and -2001 limit reg variables to behavioral statements such as RTL code. SystemVerilog extends the reg type so it can be driven by a single driver such as gate or module. SystemVerilog names this type "logic" to remind users that it has this extra capability and is not a hardware register. The names "logic" and "reg" are ...
Verilog was later submitted to IEEE and became IEEE Standard 1364-1995, commonly referred to as Verilog-95. In the same time frame Cadence initiated the creation of Verilog-A to put standards support behind its analog simulator Spectre. Verilog-A was never intended to be a standalone language and is a subset of Verilog-AMS which encompassed ...
System Verilog is the first major HDL to offer object orientation and garbage collection. Using the proper subset of hardware description language, a program called a synthesizer, or logic synthesis tool , can infer hardware logic operations from the language statements and produce an equivalent netlist of generic hardware primitives [ jargon ...
This is the technique used by the chip estimation system (CES). Steps: Identify the functional blocks such as counters, decoders, multipliers, memories, etc. Assign a complexity in terms of gate equivalents. The number of GE’s for each unit type are either taken directly as an input from the user or are fed from a library.
SystemVerilog DPI (Direct Programming Interface) is an interface which can be used to interface SystemVerilog with foreign languages. These foreign languages can be C, C++, SystemC as well as others. DPIs consist of two layers: a SystemVerilog layer and a foreign language layer. Both the layers are isolated from each other.
The need for software tools is because of the complexity of the circuitry within the FPGA and the function the designer wishes to perform. FPGA designs are described using logic diagrams containing digital logic and hardware description languages such as VHDL and Verilog. These will then be put through an automated place-and-route procedure to ...
Reconfigurable computing is a computer architecture combining some of the flexibility of software with the high performance of hardware by processing with flexible hardware platforms like field-programmable gate arrays (FPGAs).
An inferior placement assignment will not only affect the chip's performance but might also make it non-manufacturable by producing excessive wire-length, which is beyond available routing resources. Consequently, a placer must perform the assignment while optimizing a number of objectives to ensure that a circuit meets its performance demands.
