Example text

1 Declaring and Initializing Fixed-Size Arrays Verilog requires that the low and high array limits must be given in the declaration. Since almost all arrays use a low index of 0, SystemVerilog lets you use the shortcut of just giving the array size, which is similar to C’s style. [15] You can create multidimensional fixed-size arrays by specifying the dimensions after the variable name. 5 creates several two-dimensional arrays of integers, 8 entries by 4, and sets the last entry to 1. Multidimensional arrays were introduced in Verilog-2001, but the compact declaration style is new.

Bugs are what you get when there is a discrepancy. The behavior of the device when used outside of its original purpose is not your responsibility, although you want to know where those boundaries lie. The process of verification parallels the design creation process. A designer reads the hardware specification for a block, interprets the human language description, and creates the corresponding logic in a machine-readable form, usually RTL code. To do this, he or she needs to understand the input format, the transformation function, and the format of the output.

With all this action, data alignment and timing bugs are sure to occur. At this level you are able to run sophisticated tests that have the DUT executing multiple operations concurrently so that as many blocks as possible are active. What happens if an MP3 player is playing music and the user tries to download new music from the host computer? Then, during the download, the user presses several of the buttons on the player? You know that when the real device is being used, someone is going to do all this, and so why not try it out before it is built?
