In the automated design of integrated circuits, signoff (also written as sign-off) checks is the collective name given to a series of verification steps that the design must pass before it can be taped out. This implies an iterative process involving incremental fixes across the board using one or more check types, and then retesting the design.
In 2000, EVE was founded in France. [1]In 2002, EVE launched its flagship ZeBu's first emulation product and SystemC support. [2]In May 2006, EVE introduced a communication link to SystemVerilog simulation, SystemVerilog assertion support, and a register transfer level compiler for mapping an ASIC or System-on-a-chip (SOC) design into ZeBu's arrays of FPGAs.
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.
When a process calls fork, it is deemed the parent process and the newly created process is its child. After the fork, both processes not only run the same program, but they resume execution as though both had called the system call. They can then inspect the call's return value to determine their status, child or parent, and act accordingly.

The fork/join pair are used by Verilog to create parallel processes. All statements (or blocks) between a fork/join pair begin execution simultaneously upon execution flow hitting the fork . Execution continues after the join upon completion of the longest running statement or block between the fork and join .
A formal equivalence check can be performed between any two representations of a design: RTL <> netlist, netlist <> netlist or RTL <> RTL, though the latter is rare compared to the first two. Typically, a formal equivalence checking tool will also indicate with great precision at which point there exists a difference between two representations.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (metal oxide semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunications technologies.
