Each module can be thought of as a function in C – it’s a set of lower-level routines which can be reused in your main program. The Verilog projects show in detail what is actually in FPGAs and how Verilog works on FPGA. The sensitivity 1. In the example below, mode is a local variable within tb and can be accessed by both programs p1 and p2. It is a language used for describing a digital system such as a network switch, a microprocessor, a memory, or a flip-flop. Courtesy of Arvind L03-3 1. Most digital designs are done at a higher level of abstraction like RTL, although at times it becomes intuitive to build smaller deterministic circuits at a lower level by using combinational elements like and and or. [3] Chi-Lai Huang had earlier worked on a hardware description LALSD, a language developed by Professor S. The designer has to bear in mind how data flows within the design. It behaves the same as SR flip flop except that it eliminates undefined output state (Q = x for S=1, R=1).
