The above figure describes the debouncing output result, when the Push Button is pressed. When you pull down the push button from high to low state. It bounce back to high and low few

They are Asynchronous and Synchronous Reset. Asynchronous Reset Asynchronous Reset circuit is independent of free running clock. Which means Reset circuit got no knowledge of Clock input.

It can be configured as different data width 16Kx1, 8Kx8, 4Kx4 and so on. BRAM can be excellent for FIFO implementation. Multiple

Digital Clock Manager DCM integrates advanced clocking capabilities to FPGA global clock distribution network. It eliminates clock deskewing, Phase shifting, and also act as frequency synthesizer multiply/divide input clock. Clock Deskewing The
Last updated on May 17th, 2016 at 08:01 pmWhat is FPGA Configuration? The FPGA is made of SRAM (Volatile Memory) so the data configured inside FPGA lost at power Off state. FPGA Configuration is the process of loading the FPGA chip with Configuration data through external devices during power On state. The Method of Configuring FPGA Can be divided
Last updated on July 21st, 2017 at 06:29 amWhat is FPGA? Field-programmable gate array (FPGA) is a device that has array of Configurable logic gates and can be programmed on-board through dedicated Joint Test Action Group (JTAG) or through any other serial/ Parallel non-volatile Memory. FPGA architecture are based on static random-access memory (SRAM) Volatile memory.
