Description: Simple digital frequency meter using complex programmable logic device FPGA, VHDL programming integration of all functional modules on a single chip. Functional modules, including time-base pulse generator, counters, and display data latch circuit 4. Design before the design of various functional modules, respectively, and debugging simulation results correctly, and then combine the various functional modules. Finally, for the overall simulation, download, be kind. As a result of the production of digital hardware design, stability, reliability is far higher than the use of single-chip microcomputer or analog means of the system, a simple peripheral circuits. The digital frequency meter to achieve the desired requirements of the variable-range measurement, measuring range 0.1Hz-9999MHz, accuracy up to 0.1Hz.
