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 .
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.
Physical verification is a process whereby an integrated circuit layout (IC layout) design is verified via EDA software tools to ensure correct electrical and logical functionality and manufacturability. Verification involves design rule check (DRC), layout versus schematic (LVS), XOR (exclusive OR), antenna checks and electrical rule check ...
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.
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.
For example, Mentor Graphics uses Standard Verification Rule Format (SVRF) language in their DRC rules files and Magma Design Automation is using Tcl-based language. [3] A set of rules for a particular process is referred to as a run-set, rule deck, or just a deck. DRC is a very computationally intense task. [4]
The Open Verification Methodology (OVM) is a documented methodology with a supporting building-block library for the verification of semiconductor chip designs. The initial version, OVM 1.0, was released in January, 2008, [ 1 ] and regular updates have expanded its functionality.
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.
