1. A functional simulation simulates the design description to verify its logical correctness. A circuit represented in the form of logic expressions can be simulated to verify that it will function as expected. The tool that performs this task is called a functional simulator. 2. Functional simulation is necessary for complex designs, because early detection […]

1. A synthesized circuit’s operation may be functionally correct, but it may not meet one or more timing constraints given in its specification. A timing simulation allows us to determine the speed at which the synthesized logic will operate when later programmed into the target PLD. 2, Timing simulations are also referred to as post-

1. A place-and-route (or fitter) tool is software used to automatically map or fit synthesized logic to a target PLD’s architecture. 2. The place operation selects and configures specific logic primitives in the PLD’s architecture for each logic primitive in the technology dependent netlist. 3. The route operation determines the path for each connection between

1. In electronics, logic synthesis is the process by which an abstract form of desired circuit behaviour, typically at RTL level, is turned into a design implementation in terms of logic gates, typically by a computer program called a synthesis tool. 2. The synthesized logic is optimized in terms of area (number of gates) and/or

1. In an event-driven simulation, time is advanced in non-uniform steps whose sizes depend on when event occurs. 2. It responds to each i/p event by executing a sequence of simulation cycles that determine when and to what values the simulated system’s signals change. 3. Advantages: Eliminates the need for the simulator to evaluate the
