A generate–endgenerate construct (similar to VHDL's generate–endgenerate) allows Verilog-2001 to control instance and statement instantiation through normal decision operators (case–if–else). Using generate–endgenerate, Verilog-2001 can instantiate an array of instances, with control over the connectivity of the individual instances.
New integer types: SystemVerilog defines byte, shortint, int and longint as two-state signed integral types having 8, 16, 32, and 64 bits respectively. A bit type is a variable-width two-state type that works much like logic. Two-state types lack the X and Z metavalues of classical Verilog; working with these types may result in faster simulation.
The e language uses an aspect-oriented programming (AOP) approach, which is an extension of the object-oriented programming approach to specifically address the needs required in functional verification.
A bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure . A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly.
The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from OVM (Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) for the e verification language developed by Verisity Design in 2001.
The Verilog Procedural Interface (VPI), originally known as PLI 2.0, is an interface primarily intended for the C programming language.It allows behavioral Verilog code to invoke C functions, and C functions to invoke standard Verilog system tasks.
PLA schematic example. A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits.The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output.
C to HDL tools convert C language or C-like computer code into a hardware description language (HDL) such as VHDL or Verilog.The converted code can then be synthesized and translated into a hardware device such as a field-programmable gate array.
