If statement. The if statement in Verilog is a sequential statement that conditionally executes other sequential statements, depending upon the value of some condition. 12. Design, simulate, and verify in Verilog a 4-entry FIFO that can hold 64-bit data. 1 bit and 4 bit comparator verilog code, Read More I recommend Pile of Cores on GitHub. // Verilog硬件设计最高境界:胸中有沟壑,清晰明白每一条语句所代表硬件电路 `timescale 1ns / 100ps // 0. This is a project about VLSI design. Generic FIFO implementation with optional FWFT. This video illustrates how to run a simple example of a TLM fifo D Flip-Flop is a fundamental component in digital logic circuits. Most of my experience is in VHDL.
