Ifdef Verilog Usage

Verilog for Loop - ChipVerify.

A for loop is the most widely used loop in software, but it is primarily used to replicate hardware logic in Verilog. The idea behind a for loop is to iterate a set of statements given within the loop as long as the given condition is true. This is very similar to the while loop, but is used more in a context where an iterator is available and the condition depends on the value of this iterator..
