Verification Tools

Nora:After the design description is entered and de-linted, then what?
Luigi:Once a design description is “clean,” we need to verify its functions (does it work as expected?). The designer prepares a sequence of inputs to the logic (block or chip) with expected outputs.

The inputs consist of a set of signals going into the logic. A set of output signals comes out of the logic. The digital signals are two level (high or low) electrical voltages. You recall that the two voltages can be called ones and zeros as well.

These input and output data sets are known as test patterns or test vectors. They are prepared manually, or with the help of an EDA test bench tool. A test bench is a software platform that helps to create test patterns ...
